Winter air feels gentle, but UV rays penetrate clouds and reflect off snow, doubling exposure risks for aging and damage. Daily broad-spectrum sunscreen shields against UVA-induced wrinkles and UVB burns, even indoors near windows.
Persistent UV Threats
Up to 80% of UV rays pass through clouds, while UVA penetrates glass to cause deep-layer aging like sagging and spots. Snow reflects rays intensely, amplifying damage during walks or vacations sports demand reapplication every 2 hours.
Dryness and Barrier Protection
Cold winds and low humidity weaken the skin barrier, making it prone to dehydration and irritation that UV worsens. Hydrating sunscreens with ceramides or hyaluronic acid lock in moisture while blocking rays, preventing flakiness and dullness.
Pigmentation and Long-Term Health
Uneven tone, dark spots, and hyperpigmentation persist from summer without winter SPF, as rays trigger melanin overproduction year-round. Consistent use reduces skin cancer risk and supports repair, keeping complexion even and radiant.
Application Tips
Choose SPF 30+ broad-spectrum (PA+++), non-comedogenic formulas; apply generously 15 minutes before exposure and reapply after sweating or toweling. Opt for lightweight, antioxidant-enriched versions with vitamin C for glow layer over moisturizer, under makeup.
