How to boost the effectiveness of any sunscreen.

Ever feel like you lather on the sunscreen but somehow you can just feel your skin prematurely aging in spite of your best efforts to protect it? First, remember, sunscreen alone is not enough. Second, sunscreen must be applied BEFORE you go outside so it can chemically bond with your skin. This is a case where “a little dab’ll do ya” will not be the protection you need and a giant hat becomes your skin’s best friend.

So what happens when your skin isn’t properly protected? Besides the obvious redness of a sunburn, from a cellular point of view, the creation of a free radical hailstorm is what happens.

Free radicals! What pesky little buggers they are! Latching on to your collagen layer and damaging it like some freaky kudzu vine smothering a tree.

These unstable molecules are formed when UVA and UVB rays contact your skin. They need to stabilize themselves so they look for a nice big attractive molecule to hook up with – that’s where your collagen molecule comes in. Yep- free radicals are swiping right every single time a collagen molecule shows up nearby.

So why is that a problem? When free radicals hook up with your collagen molecules, they damage them. The result is thin, crepe-y looking skin.

“Hanson found that the stratum corneum – the skin’s main protective barrier against environmental assault – generated a tremendous number of free radicals when exposed to ultraviolet light. “These free radicals caused considerable damage to both the cytoplasm and the lipid matrix,” she said. “The cytoplasm of the lower epidermis was also dramatically damaged.”

So what can you do about it? Well, first, as we have mentioned many times (think broken record), use a good physical sunscreen so the UV radiation doesn’t come into contact with your skin.

Can we ever be sure that we’ve completely covered every square inch of skin? Nope.

That’s where antioxidants (sunscreen super-boosters) enter the scene. Where your sunscreen fails to protect and block UV radiation, antioxidants step in as your plan B, kicking butt on the free radicals that are formed.

Which antioxidants boost your sunscreen protection the most? Studies show that vitamin C is the hands-down winner but vitamin E is powerful as well – and both perform better with a helping of ferulic acid.

“CONCLUSION: CEFer (C, E, and Ferulic Acid) provided substantial UV photoprotection for skin. It is particularly effective for reducing thymine dimer mutations known to be associated with skin cancer. Its mechanism of action is different from sunscreens and would be expected to supplement the sun protection provided by sunscreens.

So YES, never forget your sunscreen but make sure you’ve got some antioxidant back-up to keep the free radicals out of your life along with the wrinkles and brown spots and lack of elasticity that come with them.

We offer a variety of antioxidant products that will act as your security detail when the cray-cray free radicals come calling: Vitamin C+ Firming serum. F*a*C*E Synergy serum (C, E and Ferulic Acid, Niacinamide), CSRx Antioxidant Defense Complex, all of our Transforming Infusion product line plus Antioxidant Perfecting Cleanser and Toner.

Each of these layer perfectly under sunscreen. No balling up or weird texture changes – just a big added boost of free radical protection.

“Theoretically, supplementing sunscreens with antioxidants could boost the body’s natural defense against the formation of UVA-induced free radicals; therefore serving as a second layer of protection against UV radiation that passes through the first layer of UV protection.””

Remember to apply your antioxidant favorite first then your favorite physical sunscreen BEFORE you go out in the sun so it can properly bond with your skin.

As always, comments and questions are welcomed and appreciated.

UV Rays continue to damage DNA hours after exposure.

Damage After Dark—UV Effects Continue Long After Exposure

NOTE from Cellular Skin Rx: Damage from UV rays can be mitigated even after a burn by applying Vitamin E oil and CSRx Antioxidant Defense Complex to the skin. Both absorb the free radicals that continue to be present and actively damaging DNA for hours after the initial exposure. Ever notice how once you feel burned, it seems like the burn is way worse hours later or in the middle of the night? That is the effect of the UV radiation absorbed by the skin continuing to radiate throughout the dermal layers. Thankfully, CSRx Antioxidant Defense Complex and simple Vitamin E oil that can be purchased at any drugstore stop this inflammatory cascade and absorb free radicals before they can do maximum damage to the skin. Aloe vera might make you feel better but it does nothing to stop the inflammatory/DNA damage cascade that starts once your skin has been over-exposed to UV rays.

Much of the damage that ultraviolet radiation (UV) does to skin occurs hours after sun exposure, a team of Yale-led researchers concluded in a study that was published online February 19 by the journal Science.

Exposure to UV light from the sun or from tanning beds can damage the DNA in melanocytes, the cells that make the melanin that gives skin its color. This damage is a major cause of skin cancer, the most common form of cancer in the United States. In the past, experts believed that melanin protected the skin by blocking harmful UV light. But there was also evidence from studies suggesting that melanin was associated with skin cell damage.

In the current study, Douglas E. Brash, clinical professor of therapeutic radiology and dermatology at Yale School of Medical, and his co-authors first exposed mouse and human melanocyte cells to radiation from a UV lamp. The radiation caused a type of DNA damage known as a cyclobutane dimer (CPD), in which two DNA “letters” attach and bend the DNA, preventing the information it contains from being read correctly. To the researchers’ surprise, the melanocytes not only generated CPDs immediately but continued to do so hours after UV exposure ended. Cells without melanin generated CPDs only during the UV exposure.

This finding showed that melanin had both carcinogenic and protective effects. “If you look inside adult skin, melanin does protect against CPDs. It does act as a shield,” said Brash, also a member of Yale Cancer Center. “But it is doing both good and bad things.”

The researchers next tested the extent of damage that occurred after sun exposure by preventing normal DNA repair in mouse samples. They found that half of the CPDs in melanocytes were “dark CPDs”—CPDs created in the dark.

In searching for an explanation of these results, Sanjay Premi, associate research scientist in the Brash laboratory, discovered that the UV light activated two enzymes that combined to “excite” an electron in melanin. The energy generated from this process—known as chemiexc­itation—was transferred to DNA in the dark, creating the same DNA damage that sunlight caused in daytime. Chemiexc­itation has previously been seen only in lower plants and animals.

While noting that news of the carcinogenic effect of melanin is disconce­rting, the researchers also pointed to a ray of hope: The slowness of chemiexc­itation may allow time for new preventive tools, such as an “evening-after” sunscreen designed to block the energy transfer.
