Ingredient review
Lactamide
INCI: Lactamide
A gentle humectant that helps attract moisture to the skin, similar to lactic acid but without the exfoliating effect.
In plain English
Lactamide is a moisture-attracting ingredient made from lactic acid. Unlike lactic acid, it does not exfoliate or cause tingling, making it a milder option for adding hydration. It works by pulling water from the environment into the outer layer of your skin, helping it feel softer and more supple. You'll often find it in moisturizers and serums aimed at dry or sensitive skin.

Quick decision guide
Useful, but context matters
Lactamide is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Lactamide.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
Lactamide is the amide form of lactic acid, meaning it has been chemically modified to reduce its acidity. It is a small molecule that acts as a humectant, binding water to the skin's surface.
How it works
As a humectant, lactamide draws moisture from the air or deeper layers of the skin into the stratum corneum (the outermost skin layer). It also helps improve the feel of a product, making it spread more smoothly and leaving a non-greasy finish.
Pros
Gentle hydration
Lactamide provides moisture without the stinging or exfoliation that lactic acid can cause, making it suitable for sensitive or compromised skin barriers.
Improves product feel
It helps skincare products spread more smoothly and leaves a soft, non-sticky finish, enhancing the overall user experience.
Cons and cautions
Limited research
Compared to humectants like glycerin or hyaluronic acid, lactamide has fewer studies backing its long-term efficacy and benefits.
Climate dependent
In very dry environments, humectants like lactamide can sometimes draw moisture from deeper skin layers if not paired with an occlusive ingredient, potentially leading to more dryness.
Best for
- People with dry or dehydrated skin looking for a gentle humectant
- Those with sensitive skin who cannot tolerate exfoliating acids
Use caution if
- Anyone with a known allergy to lactic acid derivatives (rare)
Usage tips
Safety summary
Lactamide is considered safe for topical use with a low risk of irritation or allergy. It is non-comedogenic and well-tolerated even by sensitive skin types. As with any ingredient, patch testing is recommended for those with very reactive skin.
Research notes
Lactamide is less studied than other humectants, but existing research supports its role as a mild moisturizer. It is often included in formulations as a secondary humectant to improve skin feel and hydration without exfoliation.
Common label clues
- Typical concentration
- Typically used at 0.5% to 3% in leave-on products
- Regulatory status
- Generally recognized as safe for use in cosmetics at typical concentrations. No specific restrictions by major regulators (FDA, EU CosIng).
- Common uses
- Moisturizers, Serums, Toners, Cleansers
- Environmental note
- Lactamide is typically produced synthetically and is biodegradable, posing low environmental risk at the concentrations used in rinse-off and leave-on products.
Good to know
- Lactamide is sometimes listed as 'Lactamide MEA' on ingredient labels, which is a similar compound used for foam boosting in cleansers.
- It is not the same as lactamide MEA, which is more common in shampoos and body washes.
