What is Phytantriol?
Phytantriol is a cosmetic ingredient. A conditioning ingredient occasionally named on pore-clogging lists in the low range.
Where Phytantriol shows up
You'll most often find Phytantriol in a range of cosmetic products. Separately from clogging, its irritancy is rated 0/5 — low, so it's unlikely to sting or sensitise on its own.
Is Phytantriol bad for acne-prone skin?
That low score makes Phytantriol a reasonable choice even for acne-prone skin. As always, individual reactions vary, but it is not a likely cause of clogged pores.
Worth flagging: Phytantriol's rating is disputed. Credible sources land on different numbers, which is why we show a range rather than a single score — and why your own experience is the best tiebreaker.
