Reddit take

AI summary of the Reddit excerpts below — not a quote

Sulfur soap is widely recommended by users as an effective and affordable treatment for acne and excessively oily skin. It is valued for its ability to kill bacteria, reduce oil production, and unclog pores, making it a popular choice for both facial breakouts and body acne (specifically back acne). However, its potency comes with a significant risk of skin dehydration and irritation, leading many to suggest it be used in moderation rather than as a standard daily cleanser.

Pros

  • Effective for active acne breakouts and back acne
  • Significantly reduces skin oiliness
  • Helps unclog pores and kill acne-causing bacteria
  • Very affordable compared to other acne treatments

Cons

  • Can be very drying to the skin
  • Potential for irritation, especially with frequent use

Caveats

  • Moderation is key; some users suggest using it only once a week or every three days to avoid over-drying
  • Leaving the soap on the skin for too long can increase the risk of irritation
  • Individual results vary, as some users find it too harsh for their specific skin type

Best for

  • Very oily skin types
  • Treating back acne (bacne)
  • Managing active inflammatory breakouts

Avoid if

  • You have naturally dry or sensitive skin
  • You are looking for a gentle, non-stripping daily cleanser

If i get a breakout *now,* all the fixes like sulfur soap or lion acne cream or whatever, they actually work to fix it.

Sulfur soap and ketoconazole shampoo on my face did help slightly BUT every three days or so - or even once a week is fine because moderation is key.

[This sulfur soap] also helped, but it was more drying for me.

The biggest downside is it can be drying/irritating, especially if you use it daily or leave it on too long.

Yeah, sulfur soap actually can help with back acne it’s been used for years because it reduces oil, kills acne bacteria, and helps unclog pores.

If this doesn't work, you can try to use a salicylic acid cleanser instead of the soap/shower gel you shower with. Or sulfur soap or benzoyl peroxid.

Would sulphur soap work too?
