Papain
Papain is an enzyme from unripe papaya that digests surface keratin to lift away dead skin cells, giving an exfoliation mechanism that's mechanically different from an acid's — no pH-dependent penetration, no acid tingle. It's a reasonable alternative for someone who wants exfoliation but reacts badly to AHAs or BHAs.
How it works
A proteolytic enzyme from unripe papaya that digests surface keratin proteins to lift dead skin cells, giving an exfoliation mechanism distinct from acid-based chemical exfoliants.
In practice, it's typically used in a mask format a few times a week rather than as a daily leave-on step — more a periodic resurfacing treatment than an everyday acid.
How to introduce it
Wait about 10 minutes before the next step. Judging Papain before week 6 means judging it before it's had time to actually work — most of what reads as "this isn't doing anything" in the first couple of weeks is just too early to tell.
- Rinse-off use only, on clean skin — not left on overnight.
- Do not apply to broken or actively irritated skin.
Who should be careful
Papain is rated moderate risk. Patch test on your inner forearm 48 hours before first facial use, especially if your skin reacts easily to new products.
Common in these product forms
Among the products Skinzy tracks in India that contain Papain, it most often shows up as a serum or a treatment.
Questions people ask
An enzyme exfoliant from papaya that lifts dead skin without an acid's pH-driven penetration — a gentler mechanical alternative.
Most people see a fair result around 6 weeks of consistent use — judging earlier usually means judging too soon.
