Ammonium lactate is a topical medication used to treat dry, rough, or flaking skin conditions. It functions as a humectant, drawing moisture to the skin's surface, and as an exfoliant, helping to remove dead skin cells [1]. This dual action improves skin texture and hydration [1].
What skin conditions can ammonium lactate treat?
Ammonium lactate is primarily prescribed for conditions characterized by dry, rough, or scaly skin. This includes ichthyosis, a group of genetic skin disorders that cause dry, thickened, or scaly skin, and xerosis, which is severe dry skin [1]. It can also be beneficial for other conditions that result in skin dryness and scaling.
How does ammonium lactate work to improve skin?
The active ingredient, ammonium lactate, is a salt of lactic acid. Lactic acid is an alpha hydroxy acid (AHA) [2]. As a humectant, ammonium lactate attracts water molecules from the environment and binds them to the stratum corneum, the outermost layer of the skin, thereby increasing skin hydration [1]. As an exfoliant, it helps to break down the bonds between dead skin cells, promoting their shedding and revealing smoother, softer skin beneath [1].
Are there different strengths or formulations of ammonium lactate?
Ammonium lactate is available in different concentrations, typically as a lotion or cream. Common strengths include 12% ammonium lactate [1]. The choice of formulation and strength depends on the severity of the skin condition being treated and the prescriber's recommendation.
What are the potential side effects of using ammonium lactate?
When applied topically, ammonium lactate can cause localized side effects. These may include mild stinging, burning, or redness, particularly when first starting treatment or if applied to broken or irritated skin [1]. Sun sensitivity can also increase, so using sun protection is advised [1]. Serious side effects are rare.
How long does it take to see results from ammonium lactate?
The time it takes to observe improvements varies depending on the individual and the skin condition being treated. However, many users report a noticeable softening and smoothing of the skin within a few days to a couple of weeks of consistent application [1]. Continued use is often necessary to maintain these benefits.
