Hydrocortisone
Low-potency topical corticosteroid found in anti-itch creams. Ongoing facial use is the most consistent trigger for perioral dermatitis.
What it does
Hydrocortisone is a low-potency corticosteroid that calms itch and inflammation short-term, which is why it shows up in many anti-itch and bite creams. On facial skin it cuts both ways: dermatology reviews consistently identify ongoing topical steroid use as the leading trigger for perioral dermatitis, and stopping after regular use can bring a temporary rebound flare. It is not a routine skincare step — 1% is available over the counter in the US, stronger versions by prescription, and sustained face use belongs under a derm's guidance.
