Ammonium lactate is a substance with applications in both medicine and cosmetics. Here's a breakdown of its properties and uses:

Medical Uses:

• Keratolytic (dissolves keratin): Ammonium lactate is most commonly used topically as a keratolytic agent. Keratin is a protein that forms the outer layer of our skin. Ammonium lactate helps break down excess keratin, which can be beneficial in treating several skin conditions:
  • Ichthyosis: This is a group of inherited skin diseases characterized by dry, thickened, and scaly skin. Ammonium lactate helps soften and remove these scales, improving the appearance and texture of the skin.
  • Psoriasis: In some cases, topical ammonium lactate can be used to help manage psoriasis by reducing scaling and improving skin smoothness.
  • Keratosis Pilaris (KP): This common skin condition causes small, rough bumps on the upper arms, thighs, and buttocks. Ammonium lactate can help exfoliate and smooth these areas.

Cosmetic Uses:

• Exfoliant: Due to its mild keratolytic properties, ammonium lactate can also be found in some skincare products as an exfoliant. It helps remove dead skin cells, promoting smoother and brighter skin.
• Moisturizing: Ammonium lactate can also attract and retain moisture in the skin, offering some hydrating benefits.

Safety:

• Ammonium lactate is generally safe for topical use when used as directed. However, irritation can occur in some people, especially with higher concentrations or prolonged use.
• It's always best to do a patch test on a small area of your skin before applying it more widely.
