Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate pore cleansing for your dry skin due to sulfur and kaolin, but the formulation's bentonite and kaolin can exacerbate dryness, counteracting the benefits of glycerin and aloe vera.
- While the product is free from harsh irritants and contains soothing aloe barbadensis leaf juice, its drying ingredients make it unsuitable for your dry skin type.
How to apply
- Use this cleansing mask PM as part of your weekly routine, starting 1x/week and increasing slowly if needed. Always follow with a rich moisturizer to prevent dryness.
- Apply the cleansing mask after using your cleanser and enzyme powder, but before your hydrating toner and moisturizer. This ensures the mask works effectively on your dry skin.
- Smooth an even layer of the cleansing mask over your face while avoiding any rubbing. Let it sit for the recommended time before gently rinsing it off.
- Apply the cleansing mask to clean, dry skin for the best comfort. Since your skin is dry, this method helps prevent any potential irritation.
- Avoid the sensitive eye area during application. Do a patch test before your first use to ensure your skin tolerates the product well.

Questions and answers
Why does Lovi advise caution with Peter Thomas Roth Therapeutic Sulfur Mask for dry skin?
Which ingredients make this mask a poor fit for dry skin?
The sulfur, bentonite clay, and kaolin clay in this mask can make it a poor fit by worsening dryness on dry skin. A cleansing mask for dry skin needs gentle hydrating ingredients and soothing agents like glycerin and aloe vera to leave the skin soft and comfortable.
What does Kaolin Clay do for dry skin?
Kaolin clay helps absorb excess oil and impurities while maintaining skin balance, making it suitable for dry skin when used gently. A quality product for dry skin needs soothing ingredients and extra moisture to prevent any tightness and keep the skin soft.
International Journal of Pharmaceutics, 2017Skin Research and Technology, 2023
Where does this mask go in a skincare routine for dry skin?
This mask is a poor match for dry skin because its clays and sulfur tend to dry the skin out further, so dry skin needs a nourishing mask instead.
Can I use this mask with retinol, and in what order?
You should not use this mask on dry skin, as its clay ingredients may worsen dryness and irritation, especially when paired with retinol. A product of this type needs rich, gentle moisturizers and barrier-repair ingredients like glycerin, ceramides, and soothing plant extracts to keep dry skin comfortable and protected.
How often should I use this mask?
This mask is a poor match for dry skin because its clays and sulfur can dry out your face further, making it unsuitable for regular use. Dry skin needs a product of this type that brings gentle cleansing along with nourishing and hydrating ingredients like glycerin and aloe vera.
Can this mask clog pores, cause breakouts or purging for dry skin?
This mask is unlikely to clog pores, but its drying ingredients can worsen flakiness on dry skin. To properly care for dry skin, this type of product needs hydrating ingredients like glycerin and soothing elements like aloe vera without the heavy clays.
Is this mask fragrance-free and alcohol-free?
It has no drying alcohol and contains fragrance (parfum).
