As beauty experts advising on skincare routines, we noted back-to-school that opened sunscreens shouldn't carry over year-to-year (see our Wednesday Q&A). But with half a tube left? Don't toss it—repurpose it smartly for zero waste.
Summer often leaves hair dry and damaged. Apply leftover suntan oil to the ends as a deep-conditioning mask. For fine or fragile strands, use before shampooing. Even without active SPF, its nourishing oils hydrate effectively.
Thicker SPF 50 creams form a barrier against pollutants, outperforming lighter moisturizers. Ideal for hands—opt for hydrating formulas. Within 12 months of opening, retain SPF benefits to fend off dark spots. Avoid the face.
Free of SPF concerns, after-sun milk surpasses standard lotions in richness, perfect for combating dry winter skin. Its vacation-fresh scent evokes sunny days—why switch routines prematurely?
