Alpha hydroxy acids are a group of natural acids found in citrus fruits, sugar cane, tomato juice, apples, grapes, and others. They work by exfoliating the superficial layers of the skin to reveal a visibly smoother and fresher complexion. The product's formula is light and absorbs quickly into the skin. The product targets uneven skin tone, fine lines, and rough skin texture. How to use: Apply 4-5 drops at night on clean and completely dry skin, avoiding the eye contour, and massage gently. After 10-15 minutes, rinse well with water. Wait until the skin dries before applying the next product.
