Ingredient review

Amylase

INCI: AMYLASE

Amylase is a gentle enzyme exfoliant that dissolves dead skin cells by breaking down surface starches, making skin smoother without harsh scrubbing.

In plain English

Amylase is a type of enzyme (a protein that speeds up chemical reactions) that breaks down starches into simple sugars. In skincare, it works on the outer layer of your skin to gently dissolve dead skin cells and buildup, leaving your face feeling smoother and looking brighter. Unlike gritty scrubs or strong acids, amylase is very mild and unlikely to cause irritation, making it a good option for sensitive skin.

Quick decision guide

Useful, but context matters

Amylase 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.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging Amylase.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. 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

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

Amylase is an enzyme naturally produced by the body (in saliva and pancreas) to digest starches. In cosmetics, it is typically produced via fermentation (biotech) and used as a gentle exfoliant.

How it works

Amylase works by targeting and breaking down alpha-1,4 glycosidic bonds in starches and polysaccharides present on the skin's surface. This loosens and removes dead skin cells and debris without the need for physical scrubbing or strong chemical peels.

Pros

Very gentle on skin

Amylase exfoliates without the sting or irritation common with AHAs or BHAs, making it suitable for sensitive or compromised skin barriers.

Biodegradable and eco-friendly

As a natural enzyme, amylase breaks down easily in the environment, unlike plastic microbeads used in some scrubs.

Cons and cautions

Limited exfoliation scope

Amylase only targets starches, so it may not effectively remove oil-based buildup or unclog pores as well as salicylic acid.

Stability challenges

Enzymes can lose activity if exposed to high heat, extreme pH, or certain preservatives, so product formulation and storage matter.

Best for

  • People with sensitive or reactive skin looking for mild exfoliation
  • Those who want to avoid physical scrubs or strong chemical exfoliants

Use caution if

  • Individuals with known allergies to enzymes or fungal-derived ingredients

Usage tips

Use enzyme products on damp skin for better activation.
Follow with a moisturizer to support skin barrier after exfoliation.
Do not mix with strong acids or high-pH cleansers in the same routine.

Safety summary

Amylase is considered safe for topical use in cosmetics at typical concentrations. Allergic reactions are rare but possible, especially in individuals with enzyme sensitivities. Avoid contact with eyes and broken skin.

Research notes

Studies confirm amylase's ability to gently exfoliate by breaking down surface starches. Evidence is moderate, with most data coming from cosmetic ingredient testing rather than large-scale clinical trials.

Common label clues

Typical concentration
0.1% to 1% in rinse-off products
Regulatory status
Approved for cosmetic use in the EU, US, and many other regions. No specific restrictions at typical use levels.
Common uses
Exfoliating cleansers, Enzyme masks, Peeling treatments
Environmental note
Amylase is produced via fermentation, a relatively low-impact biotech process, and is biodegradable.

Good to know

  • Amylase is often combined with other enzymes like protease or lipase for broader exfoliation.
  • Enzyme exfoliants are generally safe for weekly use, but always patch test first.
