Sulfur Ointment — Reddit Reviews
by De La Cruz
Updated October 17, 2026
10% sulfur spot treatment Reddit loves for inflamed breakouts; research remains limited.
What the community says
Redditors report faster-shrinking pimples and calmer rosacea or perioral dermatitis after short, 5–10-minute masks. Research found sulfur alone reduced acne spots in one trial, yet evidence remains limited. Expect eggy smell and dryness especially on compromised or sensitive skin, so start slowly.
