Boasting skincare and suncare in one step, the Lancaster Beauty Sun Perfect Unifying Serum SPF50 features a featherlight formula designed to protect skin while enhancing natural radiance. Infused with Full Light Technology and a Sun Repair System, the silky serum helps shield against UVB, UVA, visible light and infrared rays. Niacinamide and vitamin C lend their brightening and hydrating benefits, helping to visibly refine the look of uneven skin tone and textural irregularities. The ultra-light formula absorbs quickly, making it the perfect final step before makeup or providing a radiant finish when worn on its own.
