Even in winter, even under an overcast sky, our skin remains exposed to UVA rays , responsible for skin aging , brown spot formation, and certain forms of rosacea.
UVA: The Rays That Get Through Everything
-
They penetrate clouds, windows, and even some clothing fibers.
-
They are present all day long, all year round.
-
They penetrate deeply into the skin and degrade collagen and elastin.
-
They cause pigmentation spots (solar lentigines) and worsen redness.
Unlike UVB rays, which cause sunburn, UVA rays don't burn — which means you don't feel them… but they act silently.
Risks Associated with Unprotected Daily Exposure
Whether you live in the city or countryside, skin is exposed to UV rays daily. Long-term, this leads to:
1. Brown spots
UVA rays stimulate melanin overproduction, causing pigmentation spots to appear, especially on:
-
cheekbones,
-
forehead,
-
backs of hands,
-
décolletage.
These spots develop gradually, often years before becoming visible.
2. Worsening of Rosacea and Redness
UV rays amplify inflammatory phenomena:
-
increased reactivity,
-
flushing,
-
more visible vascularization,
-
persistent redness.
Sun protection therefore becomes an essential step for skin prone to rosacea or diffuse redness.
3. Premature Skin Aging
UVA rays accelerate skin aging:
-
wrinkles and fine lines,
-
loss of firmness,
-
lack of radiance,
-
thinner, more fragile skin.
According to dermatological studies, 80 to 90% of visible signs of aging are caused by the sun, even without direct exposure.
Why Apply Sunscreen Every Day?
✔ To Prevent Pigmentation Spots
Sun protection blocks the melanin stimulation caused by UVA rays, preventing spot formation and preserving an even complexion.
✔ To Limit Rosacea Flare-ups
Daily SPF reduces inflammation and protects sensitive skin, especially in cold weather when temperature variations weaken the epidermis.
✔ To Preserve Skin's Youthfulness
By limiting sun-related oxidative damage, skin remains firmer, smoother, and more luminous.
✔ To Enhance Anti-Aging Treatments
HP-DNA, peptides, and regenerating actives work even better when skin is protected from UV rays.
