Dermatologists would agree that sunscreen is the most important part of your skin care regimen. Why is that? We know that skin aging is a combination of intrinsic (genetic) factors and extrinsic (environmental) factors. When you consider that photo-aging is not only preventable but also responsible for much of the aging we see on the skin, it’s critical that we educate our clients very early on about daylight exposure.

Sun protection is also crucial to preventing skin cancer. According to The American Cancer Society, skin cancer is the most common cancer in the United States. In fact, more skin cancers are diagnosed in the US each year than all other cancers combined. The number of skin cancer cases has been going up over the past few decades. We must teach our clients about the need to limit daylight exposure and to always protect skin with sunscreen. It’s not just about going in the sun, it’s about daylight! That means sunscreen needs to be used every day – including in winter and on cloudy days!

SPF represents a sunscreen’s ability to shield against the sun’s shortwave Ultraviolet-B (UVB) rays and delay sun-induced burning or erythema. It measures the length of time a product prevents skin reddening from UVB compared to how long the skin takes to redden without protection.

For example, if you normally burn in ten minutes, when you apply a product with SPF15 (assuming you do not sweat or have any activity) and you applied the prerequisite amount to the skin (one full teaspoon just for the face!) you should be able to withstand exposure to the sun for 10 x 15 = 150 minutes.
An SPF15 product blocks about 94% of UVB rays, an SPF30 product blocks 97% of UVB rays, and an SPF45 product blocks about 98% of rays.

Based on their mechanism of action, topical sunscreens can be broadly classified into two groups, chemical absorbers and physical reflectors. Chemical absorbers work by absorbing ultraviolet (UV) radiation and can be further differentiated by the type of radiation they absorb, UVA or UVB, or both UVA and UVB (broad spectrum). Physical reflectors work by reflecting or scattering the UV radiation and will reflect both UVA and UVB.

Dermalogica Daylight Defense products have sophisticated formulations that allows clients to apply sun protection while actively treating underlying skin issues.
In addition, some of our formulas contain advanced ingredient innovations such as Oleosome Technology, a Safflower-derived, sunscreen-filled microcapsule that provides enhanced moisturization while boosting SPF without the irritation. As well as Intelligent Drone Technology which uses targeted capsules to deliver a chromophore into the skin. The chromophore Chlorella Vulgaris is activated by visible light, which provides energy—ultimately helping to boost skin’s natural luminosity.

At Dermalogica, we continually research the latest scientific breakthroughs and ingredient technologies to ensure our SPF formulas are delivering the best results to shield the skin from harmful UV rays and protect against damaging skin-aging free radicals.
