Ingredient review
Lipase
INCI: Lipase
Lipase is a gentle enzyme exfoliant that breaks down sebum and dead skin cells, making it ideal for oily or congested skin without harsh scrubbing.
In plain English
Lipase is an enzyme that acts like a tiny pair of scissors, cutting apart oil and fat molecules on your skin. In skincare, this helps dissolve excess sebum and loosen dead skin cells, leading to a smoother, clearer complexion. Unlike gritty scrubs, lipase works gently without physical abrasion, and it's often paired with other enzymes like protease for a more complete exfoliation.

Quick decision guide
Useful, but context matters
Lipase 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 Lipase.
- 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
Lipase is a naturally occurring enzyme produced by the body and also derived from microbial fermentation (e.g., from Aspergillus niger or Candida rugosa). In cosmetics, it's used to break down triglycerides (fats) into smaller components, aiding in gentle exfoliation and cleansing.
How it works
When applied to the skin, lipase catalyzes the hydrolysis of triglycerides found in sebum and the lipid matrix between dead skin cells. This breaks down oils and helps loosen and remove dead cells from the surface, promoting a smoother texture and clearer pores without the need for harsh physical scrubbing.
Pros
Gentle on skin
Lipase exfoliates by dissolving oils rather than scrubbing, making it suitable for sensitive skin types that react to physical exfoliants or strong acids.
Targets oiliness
By breaking down sebum, lipase can help reduce shine and clogged pores, which is especially beneficial for acne-prone or oily skin.
Cons and cautions
Stability challenges
Lipase is sensitive to pH and temperature; if a product is not well-formulated, the enzyme may lose activity before use, reducing its effectiveness.
Limited research
Compared to AHAs and BHAs, there are fewer studies on lipase's long-term effects and optimal usage in skincare, so its benefits are less established.
Best for
- People with oily or combination skin
- Those looking for a gentle, non-abrasive exfoliant
- Individuals with sensitive skin who react to acids
Use caution if
- People with known allergies to fungal-derived enzymes
- Those with severely compromised skin barriers (use with caution)
Usage tips
Safety summary
Lipase is considered safe for topical cosmetic use at typical concentrations. Mild irritation is possible in sensitive individuals or with prolonged contact. Always follow product instructions.
Research notes
Research supports lipase's ability to break down triglycerides on the skin surface, aiding in gentle exfoliation and sebum control. However, clinical studies on its efficacy compared to traditional exfoliants are limited.
Common label clues
- Typical concentration
- 0.01% to 1%
- Regulatory status
- Lipase is generally recognized as safe for cosmetic use in the US and EU when formulated within recommended concentrations. It is not a drug ingredient.
- Common uses
- Exfoliating cleansers, Enzyme masks, Serums
- Environmental note
- Lipase is typically produced via fermentation, a relatively sustainable process. It is biodegradable and does not contribute to microplastic pollution.
Good to know
- Lipase is often used alongside protease (which breaks down protein) for a more complete enzymatic exfoliation.
- Enzyme exfoliants are generally considered eco-friendly alternatives to plastic microbeads.
