Ammonium Lactate

What is this medication? Ammonium lactate is a topical medication used primarily to treat dry, scaly skin conditions such as xerosis and ichthyosis vulgaris. It is a combination of lactic acid and ammonium hydroxide, functioning as both a humectant and a keratolytic agent. By increasing the moisture content of the skin and promoting the shedding of dead skin cells, it helps to restore a smoother and softer texture to the affected areas.

This medication is commonly prescribed when over-the-counter moisturizers are insufficient for managing severe dryness or thickening of the skin. It works by attracting water to the skin layers and breaking down the bonds that hold dead skin cells together, allowing them to slough off more easily. Because it contains an alpha-hydroxy acid, it can increase sensitivity to sunlight, so users are often advised to apply sunscreen and wear protective clothing while using this product.
