Lovi Assistant explains

  • Offers moderate suitability for normal skin as sulfur and zinc oxide provide anti-inflammatory and antimicrobial benefits to help reduce acne lesions and blemishes. Glycerin and aloe leaf juice offer some hydration and soothing effects, though additional humectants would better support normal skin needs.
  • The formulation provides general skincare benefits like hydration and soothing, which you may notice, but lacks specialized ingredients to directly target your redness and irritation concerns.
  • The product is generally safe for your sensitive skin, with a low risk of irritation primarily from the fragrance component.

How to apply

  • Use this cleansing mask once a week as part of your weekly routine, starting slowly to see how your skin reacts.
  • Apply this product after cleansing and enzyme powder, and before your hydrating toner and moisturizer.
  • Smooth an even layer of the cleansing mask over your face, making sure to gently avoid rubbing.
  • Put the mask on clean and dry skin to keep your sensitive face calm and comfortable.
  • Do a patch test before your first use and avoid getting the mask too close to your eyes.

People Say

This mask is highly praised for its ability to rapidly clear cystic and hormonal acne, absorb excess oil, and reduce redness.

Questions and answers

How well does Peter Thomas Roth Therapeutic Sulfur Mask work for sensitive skin?

This mask works just okay for sensitive skin, as it is generally safe but lacks specialized ingredients to directly target redness and irritation. A product for this skin needs natural extracts, gentle exfoliants, and hydrating components to calm and nourish without causing irritation.

Clinical, Cosmetic and Investigational Dermatology, 2017

Which ingredients make this mask a good fit for sensitive skin?

Glycerin and soothing aloe help provide gentle hydration and comfort, while zinc oxide and sulfur assist with calming benefits. However, a cleansing mask for sensitive skin needs extra hydrating ingredients and soothing plant extracts to better calm redness and irritation.

Journal of Controlled Release, 2025Clinical, Cosmetic and Investigational Dermatology, 2017

What does Sulfur do for sensitive skin?

Topical sulfur helps manage various skin concerns with a low likelihood of irritation, though sensitive skin requires gentle formulations and careful monitoring. This type of skin needs soothing and protective ingredients like ceramides or niacinamide alongside treatments to prevent dryness and redness.

Journal of Drugs in Dermatology, 2004

What does Kaolin Clay do for sensitive skin?

Kaolin clay is a gentle option for sensitive skin because it helps absorb excess oil without causing harsh irritation. This type of ingredient is generally safe for everyday use and may help calm the skin while keeping it comfortable.

International Journal of Toxicology, 2003Archives of Dermatological Research, 2024

Where does this mask go in a skincare routine for sensitive skin?

This cleansing mask is not part of the standard daily or weekly routine for sensitive skin, though it is generally safe with a low risk of irritation from the fragrance. Sensitive skin of this type needs products with extra soothing ingredients and specialized care that directly target redness and irritation without causing disruption.

Can I use this mask with retinol, and in what order?

This mask is generally safe for sensitive skin, but because it lacks specialized ingredients to calm redness and irritation, you should use it on different nights than your retinol to avoid dryness. To help sensitive skin stay calm and smooth, a product of this type needs extra soothing hydrators and barrier-repairing ingredients.

How often should I use this mask?

This mask works safely for your sensitive skin, though other products fit it better. Sensitive skin of this type needs soothing ingredients like aloe and extra hydrators to calm redness and keep skin comfortable.

Can this mask clog pores, cause breakouts or purging for sensitive skin?

This mask is generally safe for sensitive skin, but the clays and sulfur can sometimes be drying and irritating for some people. A mask of this type needs extra soothing ingredients and hydration to keep sensitive skin calm and comfortable.

Is this mask fragrance-free and alcohol-free?

It has no drying alcohol and contains fragrance (parfum).
