Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Ammonium lactate is derived from lactic acid and is considered an AHA. It is often used to treat very dry, rough, or itchy skin.
At 12% strength, this ingredient has been shown to do more than just moisturize. Studies show it can increase skin thickness, boost natural hyaluronic acid in skin, and improve overall firmness/elasticity.
You'll likely see this ingredient in eczema treatments. Many OTC products contain this ingredient (up to 10%), but stronger versions (30%) are only available by prescription in many countries.
According to the Cosmetic Use Guidelines (CIR Expert Panel), this ingredient is safe to use at ≤10% with pH ≥3.5, provided sun protection is included. Like all AHAs, ammonium lactate makes your skin more sensitive to the sun (daily sun protection is a mustl). Without it, UV exposure can lead to damage and undo the benefits of treatment.
Be sure to listen to your medical provider when using prescription ammonium lactate.
