Snow reflects up to 80% of UV radiation, intensifying sun exposure. This can accelerate photoaging, making daily broad-spectrum SPF 30+ essential even in winter.
Retinoids (retinol, prescription-strength tretinoin) are the gold standard for stimulating collagen. Peptides help support skin structure, and antioxidants like Vitamin C protect against further damage.
A broad-spectrum sunscreen with SPF 30 or higher, applied daily. It is your primary defense against the UV rays that cause both hyperpigmentation and collagen degradation.
For sensitive skin, apply moisturizer first to buffer potential irritation. For faster absorption, apply retinol to clean, dry skin before moisturizing.
