Why adjust your routine in summer?
UVA rays penetrate the dermis and break down collagen fibers, while UVB rays cause burns and spots. The combination of heat and humidity increases cellular oxidation and alters the lipid barrier. A targeted protocol limits this damage and maintains the skin's physiological balance.
1. Vitamin C: the essential antioxidant shield
- Action : neutralizes free radicals generated by the sun, stimulates collagen synthesis, and slows down tyrosinase, which is responsible for pigment spots.
- Use : prioritize vitamin C derivatives – such as the’ascorbyl glucoside – more stable in high temperatures and light.
- Moment : in the morning before applying sunscreen and in the evening to repair the skin.
2. Antioxidant nutricosmetics: strengthening internal defenses
Supplement topical treatments with an oral antioxidant regimen (vitamin C, vitamin E, carotenoids,…) improves sun tolerance and reduces systemic inflammation induced by UV rays. Studies show more even tanning and a reduction in fine lines after 4 to 8 weeks.
3. Hyaluronic acid: deep hydration despite the heat
Capable of retaining up to 1,000 times its weight in water, the’hyaluronic acid Maintains skin suppleness, limits TEWL (transepidermal water loss), and acts as an anti-wrinkle cushion. High molecular weight forms create a protective film, while fragmented forms penetrate to plump the skin.
4. SPF 50+ broad spectrum: the non-negotiable foundation
SPF 50+ filters more than 98% of UVB rays; make sure the product also has an effective UVA rating (circled UVA logo or PPD≥16).
Apply 2 mg/cm² (= approximately one teaspoon for the face and neck) and reapply every two hours or after swimming or perspiring.
5. Lipid-rich after-sun balm: repair the skin barrier
A balm texture, concentrated in ceramides, fatty acids and cholesterol, Restores the lipid balance of the stratum corneum, calms inflammation, and prolongs tanning by limiting flaking. Clinical data indicate a recovery of barrier function within 24 hours after twice-daily application.
