This fit is calculated for the concerns frequently associated with dark spots: hyperpigmentation, sun spots, and uneven skin tone. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for skin with dark spots; other cleansing masks fit it better.

## Why this fit

- Offers moderate suitability for normal skin, as sulfur and niacinamide provide mild keratolytic action and seboregulation, which are supportive for your pigmentation concerns by offering general cleansing benefits.
- The formulation includes allantoin and dipotassium glycyrrhizate, which are soothing ingredients that contribute to a good safety profile for your normal skin.
- The product is safe for your normal skin due to the absence of prohibited or harsh ingredients and the presence of soothing components.

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

### 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 Niacinamide do for skin with dark spots?

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

This mask works well as an evening treatment step in your routine to help with cleansing and dark spots. To get better results for dark spots, this type of skin needs products with stronger brightening ingredients that directly target uneven pigment.

### How often should I use this mask?

This product works for your skin with dark spots, though other products fit it better. To care for this skin, a product of this type needs brightening ingredients and gentle exfoliants to help fade dark spots while keeping your skin calm and smooth.

Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Antioxidants, 2021](https://pubmed.ncbi.nlm.nih.gov/34439563/)
