## Questions and answers

### What makes Dr. Dennis Gross Clarifying Colloidal Sulfur Mask a great fit for skin with dark spots?

This mask is a great fit because it features ingredients like retinol and phenylethyl resorcinol that help target dark spots by encouraging cell turnover. It also uses colloidal sulfur and zinc oxide to clear out pores, while glycerin maintains your skin's moisture.
Sources: [Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/32783330/), [The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/)

### Which ingredients make this mask a good fit for skin with dark spots?

Phenylethyl Resorcinol and Retinol make this mask a great fit for skin with dark spots because they target pigmentation by helping cell turnover. Glycerin and sodium PCA also help keep your skin hydrated.
Sources: [Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/32783330/), [The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/)

### What does Sulfur do for skin with dark spots?

Sulfur is unlikely to help fade dark spots on its own, but certain sulfur compounds may improve skin pigmentation and dark patches. To effectively address dark spots, this skin type needs ingredients that target discoloration and even out skin tone.
Sources: [The Journal of Investigative Dermatology, 1987](https://pubmed.ncbi.nlm.nih.gov/3794391/)

### What does Zinc Oxide do for skin with dark spots?

Zinc oxide helps improve dark spots, melasma, and age spots when used regularly in skin preparations. Clinical studies show that preparations containing zinc oxide can successfully reduce unwanted skin darkening and even out skin tone while remaining very gentle and non-irritating.
Sources: [Journal of Drugs in Dermatology, 2026](https://pubmed.ncbi.nlm.nih.gov/41493259/)

### Where does this mask go in a skincare routine for skin with dark spots?

This cleansing mask fits into a weekly routine for skin with dark spots as an extra weekly step after cleansing and enzyme powder. It helps clear away oil and impurities while targeting dark spots.

### Can I use this mask with glycolic acid, and in what order?

It is best not to use this mask at the same time as glycolic acid, as combining exfoliating ingredients may easily cause redness, dryness, or stinging. You can safely use them on alternate days or in separate routines to keep your skin smooth and calm.

### How often should I use this mask?

This mask is a great fit for your skin with dark spots and can be used regularly in your weekly routine. It helps clear pores and target dark spots while keeping your skin calm and hydrated.

### Can this mask clog pores, cause breakouts or purging for skin with dark spots?

This mask is a great fit because colloidal sulfur and zinc oxide absorb excess oil and impurities, while retinol helps promote cell turnover to target dark spots and keep pores clear. Glycerin and sodium PCA maintain hydration without heavy oils, making it unlikely to clog pores.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### Is this mask fragrance-free and alcohol-free?

It has no drying alcohol and contains fragrance (farnesol). Cetearyl alcohol is a fatty alcohol, which soften the skin.
