How do I know which SPF to use?
Sunscreens are available in four different levels of protection: low (factor 6 to 10), medium (15 to 25), high (30 to 50) and very high (50+). The higher the protection factor the better your skin is protected, but it’s important to apply the product thoroughly (be careful not to miss any bits) and to reapply it generously every two hours.
What is high-energy visible light and why does my skin need to be protected from it?
The sunlight spectrum consists of UV, visible and infrared light. Visible sunlight can be detected by the human eye, while the others remain invisible. Part of this visible spectrum has a high energy level and is known as high-energy visible light. It is also referred to as HEVIS light, HEV Light, HEVL and sometimes ‘blue light’ or ‘blue violet light’
Like UVA rays, HEVIS light penetrates the deeper layers of skin (the dermis) and can generate free radicals. These free radicals are one of the main causes of photoaging (premature skin aging caused by the sun). They interfere with skin cells and break down the collagen and elastin that gives our skin its plump, youthful appearance. HEVIS light has also been linked to uneven skin pigmentation and melasma.
Many modern sunscreens offer effective protection against UVA and UVB rays, but we recommend that you look out for products that also defend against the negative effects of HEVIS light. These products will give your skin reliable protection from photoaging and, in the long run, can also help to combat visible signs of skin aging such as wrinkles.
Why should I integrate sun face care into my daily routine?
Facial skin is more sensitive to UVA/UVB radiation and HEVIS light than skin on the rest of the body as it is exposed to sun all year round. Sun protection can help you avoid the cellular DNA damage caused by UV, photoaging (premature aging caused by the sun) and hyperpigmentation. It is important to protect facial skin whenever it is exposed to the sun.
What is the difference between Eucerin Sun Photoaging Control Tinted SPF 50+ Medium and Eucerin Sun Fluid Photoaging Control SPF50?
Both formulas offer Eucerin’s Advanced Spectral Technology which combines broadband and photostable UVA and UVB filters1 with Licochalcone A to neutralize the free radicals caused by UV and high-energy visible light. Both formulas also include Hyaluronic Acid which visibly reduces wrinkles.
The main differences between the two products are that:
One offers very high sun protection (SPF 50+) while the other offers high sun protection (SPF 50)
One contains color pigments (Instantly unifies complexion & provide additional defense against HEVIS induced signs of aging) and the other doesn’t.
(1) Meeting the high standards for UVA and UVB protection defined by Cosmetics Europe. The levels of UVA protection are higher than the EU recommendation.
