Article, Short-Term Sun Exposure Damages Facial Blood Vessels Furthering Rosacea Symptoms and Damages – How Rosadyn+ Rosacea Support With Rosacea Friendly Sun Protection Can Help You Protect Your Skin:
In this article we warn rosacea sufferers that significant vascular damage can be caused by the sun’s Ultraviolet Rays (UV Rays) more quickly than most think — i.e. with only 20 to 30 minutes of sun exposure. Not only can UV rays cause significant damage to the very superficial vessels of the face, but they can penetrate deep into the mid-dermis and directly damage the structural integrity of much larger feed vessels; in fact, recent studies demonstrate that UV rays reach the subcutaneous fat layer. We will also discuss other adverse effects by UV rays such as stimulating uncontrolled overgrowth of blood vessels (angiogenesis) and triggering blood vessels to grow much closer to the surface. We will discuss various lifestyle actions that may put you at risk for UV-induced vascular damage and review protective gear and lotions that may not be nearly as effective as once thought. Lastly, we will discuss the strong protective actions that oral Rosadyn, a rosacea treatment oriented nutraceutical has on sun exposure and UV damage.
Rosacea And Surprising Side Effects Of Short-Term Exposure To Sun
Sun exposure is near the top of the list of rosacea triggers and causes for rosacea progression according to the National Rosacea Society (NRS). The sun’s damaging UV rays can cause many rosacea symptoms and long-term flares but the damage to blood vessels throughout the face is one of the most important with regards to progression — often causing mild rosacea sufferers to progress quickly into the moderate-to-severe stages.
Most rosacea sufferers are well educated and taught to wear sunblock everyday, especially when planning day-long outdoor activities. However, most rosacea sufferers do not realize that short term exposure to the sun’s UV rays for just 20 to 30 minutes can cause significant, irreversible damage to blood vessels in the face — in turn, exacerbating the entire disease state, the number of rosacea triggers and the duration of triggers. There are many activities that rosacea sufferers do for 20 to 30 minutes when they don’t wear sunscreen because they don’t realize the danger. While UV rays are the strongest between 10 AM and 4 PM, Dermatologist emphasize that they can still cause significant skin and vascular damage between 8 AM and 6 PM, especially in light-skinned people and rosacea sufferers.
Some activities that might catch rosacea sufferers off-guard and cause vascular damage and new telangiectasia (broken blood vessels) to form immediately after the respective activities take place, especially if they are not wearing sunscreen:
- A morning walk around the neighborhood
- Walking your dog at various times throughout the day
- Outdoor lunches at work or on balconies which usually last 30 to 60 minutes in the mid-day sun
- Short morning jogs or late afternoon jogs
- Home “Sun Rooms” — up to 70% of the UV rays penetrate normal glass
- Riding in the car — very few rosacea sufferers realize the damage that occurs when riding in the car and do not know that most of the damaging UV rays easily penetrate the front and side windows
- Outdoor Yoga or Meditation exercises in the morning or at lunchtime
- Brief outdoor meetings with friends
- Business meetings done outside
- Yard-work – especially at supposed “safe times” between 8 AM and 10 AM or 4 PM and 6 PM
- A short stroll with your baby or bicycle riding with your children
- Exposure during winter time, especially with snow on the ground which is a strong reflector of UV rays
T0 make matters worse, a significant number of rosacea sufferers with hyper-reactive skin cannot wear any form of topical sunscreen or sunblock:
- Rosacea sufferers who cannot wear any sunscreen due to hyper-sensitive skin are at the greatest risk for vascular damage and rosacea progression
- Rosacea sufferers in this category often resort to hats or reflective gear, but they still receive significant UV exposure from sunbeams reflecting off of pavement, sidewalks and even grass
- The specially designed protective sungear made by companies like Columbia are of great help but they cannot block all the dangerous rays from rosacea-sensitive skin
What happens to rosacea skin in 20 to 30 minutes?:
- Dermatologists have performed studies on this very subject. They have measured vascular changes, taken biopsies, analyzed skin cell changes, measured chemicals released from skin cells that adversely affect blood vessels and have performed studies with specialized dermatology equipment that mimics the UV rays of the sun so that experiments can be done under controlled conditions in a much safer atmosphere.
- Within 20 to 30 minutes of exposure to the sun’s UV rays, direct UV absorption into the blood vessel wall can cause total collapse of affected blood vessels and cause irreversible damage to the structure of the vessel. This type of damage often results in “broken blood vessels” or telangiectasia
- Short term sun exposure stimulates new growth and overgrowth of facial blood vessels known as angiogenesis. This is central to rosacea progression and once grown are permanent fixtures in the facial skin.
- Short term exposure causes many blood vessels to grow much closer to the surface. Often times it will cause blood vessels to grow into the epidermis which is normally devoid of blood vessels. This is a serious side effect because these superficial blood vessels are now left nearly unprotected and much more prone to environmental damage.
- Short term sun exposure greatly increases the number of mast cells around blood vessels. Mast cells contain dozens of potent dilators – thus, more mast cells usually results in increased facial redness and flushing.
- Short term sun exposure turns on inflammatory enzymes like collagenase and elastase. These two enzymes break down the skin’s architecture and eat away at blood vessels like “PAC MEN”
- Short term sun exposure stimulates damaging enzymes such as Matrix Metalloproteinases, one of the hottest subjects in rosacea research and treatment.
- Each sun exposure thins the protective epidermis, which in turn, results in more damage to blood vessels over time.
See How The Protective Actions of ROSADYN+ Helps With Sun and UV-Induced Rosacea Flares and Sun Damage
Rosadyn contains nutraceutical ingredients that are potent UV protectors that lend significant protection to facial skin and blood vessels: Eastern White Pine Bark, Mediterranean Olive Fruit Extract and Sulforaphane.
While summer is a time for relaxation, vacations at the beach and daily outdoor activities for most people, it can be a trial by fire for many rosacea sufferers. According to a large National Rosacea Society survey of several thousand rosacea sufferers in 2012, sun exposure is the #1 trigger. To make matters worse, heat exposure is listed as the third leading rosacea trigger. That means summertime is a dual threat to most rosacea sufferers and can lead many to stay in doors during the daytime hours. Rosacea sufferers must try to avoid both triggers if they are not actively undergoing treatments that address these strong triggers:
(1) Ultraviolet Rays — the sun’s ultraviolet rays (UV rays) easily penetrate the skin’s epidermis and upper dermal layers where they cause cellular death (sunburn), physically damage blood vessels, activate inflammatory enzymes and free radicals which trigger intense flushing, and cause delayed acne rosacea outbreaks (clusters of papules). It is important to note that UV rays penetrate through windows in the house and cars, so a 20 minute drive for errands can trigger all the above-mentioned side effects.
(2) Exposure to External Heat — Summer heat above 80 degrees Fahrenheit can quickly increase the temperature of facial skin. This temperature increase can trigger release of damaging free radicals, activate sensory nerves that cause burning and stinging sensations, and trigger facial flushing and long-standing facial redness by activating dilator nerves located in the brain’s hypothalamus — the thermoregulatory center — that receives feedback from heat sensing nerves in the facial skin.
(1) Rosadyn+ Incorporates Several Active Ingredients into the Plasma Membranes of Epidermal Cells — several active ingredients in Rosadyn+ incorporate themselves physically into the cell membrane of the skin’s outermost layers and also position themselves in the plasma fluid surrounding the cells. These nutraceuticals physically absorb significant amounts of UV rays (UVA and UVB) before they reach the first cell line in the epidermis — greatly reducing sunburn responses, cellular damage, vascular damage and facial redness.
Mediterranean Olive Fruit Extract — The Oleuropein extract (15%) derived from this particular Olive Fruit is an excellent UV protector. This oral extract has been tested on human skin by irradiating the skin with a machine that transmits UV rays comparable to moderate levels of sun exposure. Before Olive Fruit treatment significant sunburn reactions were noted and cellular damage was significant upon histological examination; however, in follow up studies, after three days of oral treatment with Oleuropein there was no significant sunburn reaction and the tissue was left intact without damage. Olive Fruit Extract appears to act in the dermo-epidermal junction and quench UV rays, free radicals and oxidative stress before they reach underlying cells in the dermis, thus resulting in potent protection of unwanted UV effects. [ref. 1, 2]
Eastern White Pine Bark Extract — Oral Pine bark extract is one of the most effective protectors against the sun’s UV rays. C0untless human clinical studies have demonstrated the protective effect of Pine bark extract against moderate to high levels of sun exposure. [ref. 3, 4] In fact, oral Pine Bark extract even enhances the recovery from a sunburn reaction if one forgets to pre-treat with this supplement. The active ingredient — Proanthocyanidins –is responsible for this protection and the higher concentration in your formula, the stronger the protective actions. Rosadyn+ incorporates the highest pharmaceutical grade concentrations at 95% Proanthocyanidin content. The combination of Mediterranean Olive Fruit Extract and Eastern White Pine Bark Extract makes Rosadyn+ a potent oral UV protector and is especially useful for people with rosacea or skin that burns easily.
(2) Scavenging Dangerous UV-Induced Free Radicals and Turns Off Inflammatory Enzymes — Even if you wear sunscreen, UV radiation from the sun triggers the release of very destructive free radicals in the skin that often cause long-term inflammation and can even cause a simple case of mild rosacea to evolve into moderate-to-severe rosacea after exposure to strong sun for just one long afternoon. Because of this threat, Rosadyn+ has incorporated two of the most powerful antioxidant nutraceuticals into its formula including Maqui Berry Superfruit, which is, by far, the most potent free radical scavenger ever tested. These two Superfruits also turn of key inflammatory enzymes and have potent general anti-inflammatory actions against multiple forms of sun-induced inflammation.
Maqui Berry Superfruit Extract — Oral Maqui Berry Superfruit extract is the most potent free radical scavenger available on the market. It is ideal for rosacea treatment because rosacea is a disorder of uncontrolled free radical production and Maqui Berry incorporates itself into keratinocytes (skin cells) in the epidermis and dermis making it the perfect protector against free radical generation under normal circumstances and during sun exposure. Not only does it quench free radicals before they damage skin cells, blood vessels and nerve endings, but they suppress the activity of key inflammatory enzymes (Matrix Metalloproteinases, Phosphokinase C and Tumor Necrosis Factor) that are normally activated in response to UV exposure — even while wearing appropriate sunscreen. [ref. 5]
Pomegranate Superfruit Extract — Oral Pomegranate Superfruit extract is the second strongest antioxidant according to the universal ORAC measurement. So, not only do Maqui Berry extract and Pomegranate extract exert the strongest possible antioxidant actions in facial skin, but they work synergistically to recycle each other to ensure they continue to work at their peak for extended periods of time. Skin cells irradiated with UV rays release numerous types of free radicals in very high concentrations; these cells also activate the “Master Inflammatory Switch”, an enzyme called NF-Kappa-Beta. In clinical tests, Pomegranate extract was shown to neutralize almost all UV-induced free radicals and suppress the activity of NF-Kappa-Beta. [ref. 6] These actions make Pomegranate extract and Maqui berry extract the perfect nutraceuticals to stave off dangerous UV-induced free radicals and turn off destructive inflammatory enzymes in the skin.
(3) Blocking UV-Induced Acne Rosacea Breakouts — UV exposure not only damages skin cells and causes various grades of sunburn and facial redness, but it often causes acne rosacea outbreaks. With UV radiation exposure though, it often causes inflammatory cells deep in the dermis to migrate slowly up to the skin’s surface to cause clusters of papule outbreaks. This process can take several hours after UV exposure or even occur later, while you are sleeping. For this reason, we incorporated one of the strongest anti-acne, anti-acne rosacea nutraceuticals into Rosadyn+ — Mediterranean Olive Fruit Extract — dubbed “the perfect skin supplement” by Naturopathic Physicians due to its ability to treat and prevent skin eruptions.
Mediterranean Olive Fruit Extract — This special nutraceutical not only blocks UV rays from triggering acne rosacea clusters, but it blocks the migration of acne-causing substances in the dermis. It does this by locating the migration trail of these inflammatory substances, physically attaching to these molecules and removing them through the lymphatic drainage system. [ref. 7] These molecules never have a chance to cause acne rosacea clusters because they are deactivated, never reach the skin’s surface… and for good measure, are permanently removed from the facial skin.
Protecting the Skin from Heat Build Up and Heat-Induced Flushing
(1) Rosadyn+ Reduces Heat Build Up in the Skin — Keu active ingredients in Rosadyn+ incorporate themselves physically into the cell membrane of the skin’s outermost layers which fortifies the membrane and protects each cell from absorbing ambient heat. This reduces heat build up in the skin. One particular nutraceutical also positions itself in the plasma fluid surrounding the cells which keeps large amounts of water moving around each individual cell which greatly reduces heat build up. This two pronged action protects the skin from overheating and triggering heat-induced flushing.
Eastern White Pine Bark Extract — Proanthocyanidins from White Pine Bark Extract are central to reducing heat build up in the skin and subsequent heat-induced flushing. These tiny peptides incorporate themselves into the outer membrane of surface skin cells, strengthening and reinforcing layers of cells. Normally thin cell plasma membranes would absorb heat — which would result in heat build up — however, reinforced membranes reflect heat and force most of the heat back out into the air to naturally dissipate. [ref. 3 and 4] Furthermore, at the clinical doses that we use excess Proanthocyanidins circulate in the extracellular fluid surrounding cells which increases the volume of fluid and the movement of fluid. Both of these actions significantly reduce heat-induced flushing because sensory nerves in the skin do not “sense” heat build up because it has been largely suppressed by Pine Bark’s actions.
(2) Helping Calm Heat-Induced Flushing and Burning/Stinging Sensations — The skin contains many different sets of sensory nerves to feed information back to the brain and elicit the proper reaction. With regards to UV rays, the skin contains sensory nerves that measure heat, burning sensations and stinging sensations. These stimuli are all sent to an area of the brain called the hypothalamus which is a major regulatory center for these sensory nerves. The hypothalamus analyzes these signals and sends back information to each nerve group. Rosadyn+ incorporated two key nutraceuticals that help to modulate these sensory nerves and hypothalamic actions that might not be in the best interest of rosacea skin.
PharmaGABA — This nutraceutical increases concentrations of the neurotransmitter — GABA — in the hypothalamus. GABA has a “calming” effect on the hypothalamus and tempers its response to various triggers. [ref. 8] For example, an ordinary response by the hypothalamus to increased skin heat recorded by sensory nerves would be to send signals for these nerves to release potent dilators to cause facial flushing… which dissipates heat and normalizes skin temperature. PharmaGABA suppresses this response just enough so that the vascular dilation does not provoke a flushing response, but is still able to slowly release skin heat through tiny superficial capillaries. This is a major benefit to all rosacea sufferers and makes summer heat bearable for many to enjoy outdoor activities. Furthermore, when “burning” sensory nerves and “stinging” sensory nerves are activated by high outdoor temperatures, the PharmaGABA suppresses the relay of this information to the hypothalamus so that uncomfortable burning and stinging sensations are greatly suppressed in rosacea-affected skin.
L-Theanine –This nutraceutical also increases GABA concentrations in the hypothalamus. It does this by a different mechanism of action than PharmaGABA — instead of directly supplying GABA to the brain through the blood stream, L-Theanine increases the internal production of GABA directly inside the hypothalamus and sensitizes GABA receptors so that GABA is much more efficient at any dose. [refs. 3, 4] Thus, by increasing hypothalamic levels of GABA, L-Theanine works in a similar fashion to reduce heat-induced flushing, burning sensations and stinging sensations. The incorporation of both PharmaGABA and L-Theanine into Rosadyn+ has tremendous synergistic actions and ensures that a major regulatory center in the brain acts in the best interest of rosacea sufferers.
The new Rosadyn+ formula helps target the reduction of, two of the top triggers for rosacea flares — summer sun (ultraviolet rays) and summer heat. While there are dozens of rosacea triggers, sun and heat routinely cause the most damage to rosacea skin, induce the most intense facial flushing, trigger uncomfortable burning and stinging sensations, and cause delayed acne rosacea outbreaks hours after exposure to the sun and heat. Rosadyn+ was developed, in large part, to target these two triggers and greatly reduce the intensity and duration of rosacea flares by inhibiting the penetration of the sun’s ultraviolet rays into the facial skin and minimize heat build up in the superficial skin layers.
Sun Protection Inside (Rosadyn) and Out – Don’t Forget That Topical Sunblock Too!
While the ingredients discussed above are a key part of a rosacea sufferer’s oral sun defense, we recommend daily that UV protection with sunscreen as well. That said, not all sunscreens are suitable for rosacea skin. In fact, many can cause adverse reactions, such as flushing, breakouts and redness
Often times these reactions stem from the fact that most sunscreens block UV rays with chemical agents. While those that use physical sunblocks, such as zinc oxide, are much better for sensitive skin, they traditionally had the drawback of leaving a visible white film on the skin. However, recent technological advancements have allowed skincare companies to micronize zinc oxide with dimethicone, resulting in a more cosmetically elegant product.
Do you wear sunblock everyday? If you don’t do you find yourself exposing your facial skin and blood vessels to short term sun exposure? Many Rosadyn+ clients have mentioned reduced sunburn responses after 4 to 6 weeks of use – have you noticed a difference?
Thank you for your important feedback and wishing you a rosacea-free future!
