APLB's Mandelic Acid Retinol Ampoule Serum combines the gentle exfoliating properties of mandelic acid with the anti-aging benefits of retinol to promote smoother, brighter skin. Mandelic acid helps to remove dead skin cells and refine texture, while retinol boosts collagen production, reducing the appearance of fine lines and wrinkles. This lightweight serum is ideal for normal to oily skin types.
