Ammonium lactate lotion is a topical product used to moisturize and soften very dry, rough, or flaky skin. It combines lactic acid (a mild keratolytic that helps shed dead skin cells) with a moisturizing salt (ammonium lactate), so it both hydrates the skin and gently smooths scales.
Common uses
- Very dry skin (xerosis) on arms, legs, elbows, knees, hands, and feet
- Conditions with dry, scaly skin such as ichthyosis or some forms of eczema
- Softening rough, calloused skin (often on feet or hands)
How to use (typical, but follow your product label)
- Apply a thin layer to clean, dry skin 1–3 times daily or as directed.
- Do not apply to broken or irritated skin, and avoid the eyes, lips, and mucous membranes.
- If irritation occurs (burning, stinging, redness), wash off and discontinue use. If it persists, consult a clinician.
- If you’re using other skin products, space applications apart as directed.
Precautions
- Not all products have the same strength; read the label for the exact concentration.
- Avoid if you’re allergic to lactic acid or any ingredient in the product.
- Talk to a clinician if you have diabetes, poor circulation, or are applying to large areas of skin, or if you’re pregnant or breastfeeding.
If you have a specific condition (e.g., very dry hands vs. a facial moisturizer) or you’re considering it for a child, I can tailor the guidance.
