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.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging Lipase.
  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

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

Use enzyme products as directed, typically leaving on for 5–10 minutes before rinsing.
Avoid combining with very low pH products (like strong AHAs) in the same routine, as this can deactivate the enzyme.
Store enzyme products in a cool, dry place to preserve their activity.

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.
