Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate exfoliation for your dry and flaky skin due to the presence of sulfur and bentonite, which help to dry out blemishes and absorb excess oil.
- While glycerin and aloe vera are included to provide some humectant and soothing action, the drying nature of sulfur and kaolin makes this formula less ideal for your dry skin type.
How to apply
- Use your cleansing mask PM once a week as part of your weekly routine, and increase to twice a week if your dry skin tolerates it well.
- Apply the cleansing mask after cleansing and enzyme powder, but before your hydrating toner, serum, and moisturizer.
- Smooth an even layer of the cleansing mask over your face while gently avoiding any unnecessary rubbing.
- Apply the cleansing mask to clean and dry skin to ensure better comfort for your sensitive skin type.
- Always avoid the eye area and do a patch test before using the cleansing mask for the first time.

Questions and answers
Why does Lovi advise caution with Peter Thomas Roth Therapeutic Sulfur Mask for dry sensitive skin?
Lovi advises caution because sulfur and clays in this mask dry out blemishes and absorb oil, which may make dry sensitive skin feel too dry. A product of this type needs moisturizing and nourishing ingredients that provide excellent hydration and barrier support without any risk of irritation.
Which ingredients make this mask a poor fit for dry sensitive skin?
Sulfur and kaolin clay make this mask a poor fit for dry sensitive skin because they tend to dry out the skin and absorb natural oils. A product of this type needs deeply moisturizing and nourishing ingredients like ceramides and multiple forms of vitamin C that provide excellent hydration and protect the skin barrier without any irritation.
What does Sulfur do for dry sensitive skin?
Sulfur is generally not an ideal choice for dry sensitive skin because it can be drying and irritating. Skin of this type needs gentle, hydrating ingredients and calming agents to maintain comfort and protect the skin barrier.
What does Kaolin Clay do for dry sensitive skin?
Kaolin clay is a weak fit for dry sensitive skin because it can absorb too much natural oil and leave the skin feeling stripped. A product of this type needs added moisturizing ingredients and soothing elements to keep dry skin calm and comfortable.
Where does this mask go in a skincare routine for dry sensitive skin?
This mask may not be a good fit for dry sensitive skin because sulfur and kaolin clay can dry it out. A product of this type needs nourishing oils and gentle hydrators like glycerin and aloe vera to keep this skin soft and comfortable.
Can I use this mask with retinol, and in what order?
You should avoid using this drying sulfur mask alongside retinol because the combination is likely to cause severe irritation and redness on your dry sensitive skin. A product of this type needs nourishing ingredients like glycerin and soothing aloe to keep skin calm and soft.
How often should I use this mask?
This mask is a poor match for your dry sensitive skin because its sulfur and clays tend to dry out and irritate already dry areas. A product of this type needs soothing and hydrating ingredients like glycerin and aloe vera to help keep your skin comfortable and smooth.
Can this mask clog pores, cause breakouts or purging for dry sensitive skin?
This mask is unlikely to clog pores since it contains clays that absorb oil, but it may cause dryness and irritation on dry sensitive skin. A product for this skin type needs gentle, hydrating ingredients like glycerin and soothing aloe vera to keep the skin soft without stripping its natural moisture.
Is this mask fragrance-free and alcohol-free?
It has no drying alcohol and contains fragrance (parfum).
