WHAT ARE THE BENEFITS OF AMMONIUM LACTATE ?

Because of its effects on skin keratinization, ammonium lactate is thought to result in decreased roughness of the skin, fissure development and dryness. It is also thought to reduce thickened skin. Therefore, ammonium lactate can be used for any level of xerosis, though it has been studied mostly in moderate-to-severe xerosis. When combined with other agents (e.g., pramoxine) it can have a synergistic effect for patients with dry, bothersome or itchy skin.

WHAT IS AMMONIUM LACTATE?

Ammonium lactate is a moisturizer that modulates skin keratinization, leading to epidermal proliferation and accelerated dermal cell growth. Ultimately, its presumed mechanism is to create a stimulatory action on keratinocytes and adjust the pH in the skin. Often it is combined with other agents to provide a synergistic effect in patients with xerosis.

IS AMMONIUM LACTATE SAFE FOR ALL SKIN TYPES AND TONES?

Ammonium lactate is likely safe for all skin types and tones based on available data.

CONTRAINDICATIONS

There is minimal data on contraindications for the topical application of ammonium lactate unless there is a known hypersensitivity to the agent or its derivatives. However, it may be associated with skin burning or tingling, so it should be used with caution in patients for whom this may be an issue.
