and vitamin D formation. Getting from 5 to 15 minutes of sunlight on arms, hands and face two to three times weekly will give vitamin D-boosting benefits: strong bones, healing of certain skin conditions, such as acne, psoriasis, and eczema. Matrixyl®synthe’6™, a peptide from the
Matrixyl range, has been demonstrated to boost the effect of luminotherapy on the synthesis of collagen. Six skin explants from different donors underwent experimental ageing by UVA/B irradiation and were maintained alive. They then received eight treatment sessions, over 12 days, by LED projection emitting at 600-650 nm (orange) for ten minutes and an application of a cream containing 2% Matrixyl synthe’6. Collagen production was increased by +12% with Matrixyl synthe’6 versus LED treatment only (p<0.03) and by 20% versus no treatment at all (p<0.01). Matrixyl synthe’6 is an ideal active
ingredient solution to add into luminotherapy cosmetic products or for reasonable sun exposure (daily day cream), to even out skin relief and smoothes wrinkles from the inside.
Conclusion Like skinification for hair care, sun products with added skin care benefits are gaining consumer attraction. From UV protection to skin regeneration, skinification is becoming essential to providing a holistic care to maintain a healthy and radiant skin. Sunscreens are physical or chemical defence
ingredients providing variable UV barrier protection to the skin. Their formulation, as well as consumer expectation and use, have evolved over the years. Consumers are now seeking

multifunctional sun products with added skin care benefits. Claims include anti-pollution, hydration, anti-
blemish, pigmentation prevention, brightening, antioxidant, skin regeneration, boost of natural defence mechanisms, and so on. Skinification is a complementary approach to sun protection above and beyond UV filters.
