INCI: Papain, Beta-Glucan
A dual-action ingredient that gently exfoliates dead skin cells while helping to calm and hydrate the skin.
In plain English

Papain Beta-Glucan can be useful, but watch for some irritation potential.
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 Papain Beta-Glucan.
- 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
moderateCan bother some users, especially with frequent use, damaged skin, or strong companion ingredients.
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
A combination of papain, a proteolytic enzyme derived from papaya fruit, and beta-glucan, a polysaccharide typically sourced from oats, yeast, or mushrooms. Papain dissolves keratin proteins on the skin's surface, while beta-glucan forms a hydrating film and has calming properties.
How it works
Papain works by breaking down the protein bonds that hold dead skin cells together, allowing them to be gently sloughed away. Beta-glucan sits on the skin's surface, attracting water and forming a protective layer that reduces moisture loss and soothes irritation. Together, they provide mild exfoliation with added hydration and comfort.
Pros
Gentle exfoliation
Papain dissolves dead skin cells without the need for abrasive particles or strong acids, making it suitable for regular use on many skin types.
Soothing hydration
Beta-glucan helps calm the skin and lock in moisture, which can reduce the risk of irritation that sometimes accompanies exfoliation.
Cons and cautions
Potential irritation
Enzymes like papain can cause stinging, redness, or allergic reactions in some people, especially if left on the skin too long or used at high concentrations.
Variable effectiveness
Papain's activity depends heavily on the product's pH and formulation; if not properly stabilized, it may not exfoliate effectively.
Best for
- People with dull or uneven skin texture looking for mild exfoliation
- Those with dry or sensitive skin who want a gentle alternative to acid exfoliants
Use caution if
- Individuals with known allergies to papaya or yeast-derived ingredients
Usage tips
Safety summary
Papain Beta-Glucan is considered safe for most people when used in properly formulated cosmetic products. However, papain can cause allergic reactions in individuals with latex or papaya sensitivity. Patch testing is recommended, especially for those with sensitive skin.
Research notes
Research supports papain's ability to gently exfoliate by breaking down keratin, and beta-glucan's role in skin hydration and soothing. However, most studies are small or ingredient-specific rather than on the combination. Evidence is moderate and formulation-dependent.
Common label clues
- Typical concentration
- 0.1% to 1% for papain; 0.1% to 2% for beta-glucan
- Regulatory status
- Papain and beta-glucan are generally recognized as safe for cosmetic use in the US and EU when used as directed. Papain is regulated as a cosmetic ingredient, not a drug, so it cannot claim to treat skin conditions.
- Common uses
- Exfoliating serums, Soothing masks, Brightening treatments
- Environmental note
- Papain is derived from papaya, a renewable plant source. Beta-glucan can be sustainably sourced from oats or yeast fermentation. Both are biodegradable.
Good to know
- Papain is often used in fruit enzyme masks and gentle exfoliating cleansers.
- Beta-glucan is also found in many soothing moisturizers and is considered a gentle alternative to hyaluronic acid for hydration.
