What it’s used for

Condition	How ammonium lactate helps
Dry, rough skin (e.g., eczema, psoriasis, seborrheic dermatitis)	The lactate ion mildly acidifies the stratum corneum, softening and loosening the “dead” skin layer so it sheds more easily.
Keratoses (e.g., actinic keratosis, seborrheic keratosis)	The same keratolytic action helps remove the thickened, precancerous or benign patches.
Calluses and corns	By softening the thickened skin, the cream can reduce hardness and pain.
Other scaly skin disorders	It is also used for conditions like ichthyosis vulgaris or ichthyosis vulgaris‑like disorders.

Typical use: Apply a thin layer 1–3 × daily to the affected area, keeping it covered (e.g., with a bandage) for a few hours if directed by a healthcare provider.

How it works

• Keratolytic effect: Lactic acid in the formulation dissolves intercellular lipids in the outer skin layer, allowing the stratum corneum to desquamate more readily.
• Moisturizing: Ammonium lactate also acts as a humectant, attracting water to the skin and reducing transepidermal water loss.
• pH adjustment: By slightly lowering the surface pH, it can create a less hospitable environment for some pathogenic organisms (e.g., Candida, Malassezia).

Typical dosing & application

Age group	Typical dose	Frequency	Notes
Adults & adolescents	1 – 2 tsp (~5–10 mg) per area	1–2 × daily (often after bathing)	Avoid covering the area with occlusive dressings unless advised.
Children 6 – 12 yrs	1–2 tsp	1 × daily	Use a thin layer; monitor for irritation.
Children under 6 yrs	Generally not recommended unless directed by a pediatrician.

• Apply to clean, dry skin.
• Leave on for 15–30 min (if using in a wash‑off routine) or overnight (if advised).

• Avoid contact with eyes, mucous membranes, or open wounds—the cream can sting.

Side‑effects & adverse reactions

Common	Rare	Serious
Mild itching, tingling, or burning	Contact dermatitis (rash, eczema flare)	Severe allergic reaction (anaphylaxis)
Dryness or flaking after removal	Systemic absorption (negligible)	Over‑use causing skin thinning

• Sensitivity: Some people react to the lactate or ammonium ion. If itching or burning persists, discontinue use.
• Eye irritation: If accidentally gets into eyes, rinse thoroughly with water for several minutes.

Contraindications & cautions

Category	Key points
Allergy	Known hypersensitivity to lactic acid, ammonium salts, or any other ingredient.
Open wounds or severe skin infections	Use only after a healthcare professional has evaluated the area.
Pregnancy & breastfeeding	No systemic absorption, but topical irritation can still occur. No major safety signals; still, consult a provider.
Children under 6 yrs	Not typically recommended unless directed by a pediatrician.
Concurrent use with other keratolytics	Combining multiple acids (e.g., salicylic acid, urea) may increase irritation.

Drug interactions

• Topical medications: May interfere with absorption of other topical agents (e.g., steroids, calcineurin inhibitors) if applied to the same area.
• Systemic drugs: No clinically relevant interactions are known because the cream is absorbed minimally.

---

Storage & shelf life

• Keep away from moisture and in a cool, dry place (ideal 20–25 °C).
• Shelf life: Usually 2–3 years from manufacture date; check the “best before” or expiration date on the container.
• Do not freeze or expose to extreme heat.

---

Over‑the‑counter status & purchasing

• Available in most pharmacies, supermarkets, and online OTC drug stores.
• Packaging: Typically a 30 mL or 50 mL tube.
• Regulatory status: OTC in the U.S. (under the FDA’s OTC monograph for keratolytics), similar status in the EU and Canada.

---

When to see a professional

• Persistent itching, burning, or rash that worsens after use.
• Signs of infection (redness, swelling, pus, fever).
• Uncertainty about proper dosage or suitable use in children or pregnant/breast‑feeding women.
• Use for extensive or widespread skin areas—your doctor may prefer a different formulation.

Bottom line

Ammonium lactate 12 % cream is a mild, safe, and effective topical keratolytic/emollient for many dry‑skin and scaly‑skin conditions. Use it as directed, watch for irritation, and contact a healthcare provider if you notice anything unusual. It’s not a substitute for prescription steroids or disease‑specific treatments when those are indicated.
