- Topical application of precipitated sulphur 2-8% petrolatum achieved a 95% clinical and ectoparasitological cure rate in 40 ambulatory scabies patients without relevant adverse effects.

### Which ingredients make this mask a good fit for oily acne-prone skin?

Colloidal sulfur, retinol, and zinc oxide make this mask a great fit by targeting oil production, clearing pores, and calming breakouts. Aloe barbadensis leaf juice and bisabolol add soothing benefits to keep oily skin comfortable and calm.
Sources: [Journal of Controlled Release, 2025](https://pubmed.ncbi.nlm.nih.gov/40254135/)

### What does Sulfur do for oily acne-prone skin?

Sulfur helps calm breakouts and manage oily skin by treating various skin conditions with rare mild side effects. It works well as a therapeutic agent, though products for this skin type also need ingredients that balance oil and keep pores clear.
Sources: [Journal of Drugs in Dermatology, 2004](https://pubmed.ncbi.nlm.nih.gov/15303787/), [Journal of the American Academy of Dermatology, 1988](https://pubmed.ncbi.nlm.nih.gov/2450900/)

### What does Zinc Oxide do for oily acne-prone skin?

Zinc oxide helps calm oily, acne-prone skin by reducing redness and targeting blemish-causing bacteria. It is unlikely to cause irritation and may help decrease excess oil while supporting clearer skin.
Sources: [Journal of Controlled Release, 2025](https://pubmed.ncbi.nlm.nih.gov/40254135/), [Biomedicines, 2025](https://pubmed.ncbi.nlm.nih.gov/41007718/)

### Where does this mask go in a skincare routine for oily acne-prone skin?

This cleansing mask fits into a weekly routine as a special step after cleansing and an enzyme powder, followed by a hydrating toner, treatment, and moisturizer. It helps manage oil production and breakouts while keeping your skin calm and comfortable.

### Can I use this mask with benzoyl peroxide, and in what order?

You can use this mask in your weekly routine, but it is best to avoid using it on the same days as benzoyl peroxide to lower the likelihood of dryness and irritation. Using strong acne treatments on separate days helps keep your skin calm and comfortable.

### How often should I use this mask?

You can use this mask once a week as part of your weekly routine, and people who tolerate it well and see good results can carefully use it more often. Colloidal sulfur and retinol target oil production and breakouts while keeping your skin calm and comfortable.
