The Ordinary Lactic Acid 5% + HA is a gentle exfoliating serum designed to improve the texture and appearance of the skin. This 30ml formula contains 5% lactic acid, an alpha-hydroxy acid that works to gently exfoliate the skin's surface, removing dead skin cells and promoting cell turnover. It also includes hyaluronic acid, which helps to hydrate and plump the skin, leaving it looking smoother and more radiant. This serum is suitable for all skin types, but particularly beneficial for those with dry or dull skin. With regular use, it can help to improve the appearance of fine lines, uneven skin tone, and texture, leaving the skin looking brighter, smoother, and more youthful. It is recommended for use at night after cleansing and toning, and it is important to wear sunscreen during the day when using this product.
