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 serums fit it better.

## Why this fit

- Offers moderate benefits for pigmentation due to Isobutylamido Thiazolyl Resorcinol and Glycyrrhiza Inflata Root Extract, which inhibit melanin production, and provides mild exfoliation and humectant action for your normal skin with salicylic acid and glycerin.
- The formula is safe for your normal skin as it lacks harsh ingredients and has no risk of irritation.
- While effective for acne and pigmentation, the serum could offer more emollient ingredients for optimal nourishment of your normal skin.

## Questions and answers

### How well does Eucerin Triple Effect Serum work for skin with dark spots?

This serum works moderately well for dark spots on your normal skin, helping to fade discoloration while gently clearing pores and keeping the skin calm. It is safe and unlikely to cause irritation, but a product for this skin needs richer nourishing ingredients to provide optimal softness and care.
Sources: [International Journal of Cosmetic Science, 2021](https://pubmed.ncbi.nlm.nih.gov/33559186/)

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

This serum helps fade dark spots with Isobutylamido Thiazolyl Resorcinol and Glycyrrhiza Inflata Root Extract, which slow down the production of pigment in your skin. To be a better fit for this skin type, a product of this type needs richer softening and nourishing ingredients for optimal care.

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

Thiamidol helps fade dark spots and prevents new ones from forming by targeting the root cause of uneven skin tone. It is a safe and effective option that significantly improves dark spots without causing major side effects.
Sources: [International Journal of Cosmetic Science, 2020](https://pubmed.ncbi.nlm.nih.gov/32390164/), [Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/32757247/)

### What does Salicylic Acid do for skin with dark spots?

Salicylic acid helps fade dark spots and uneven skin tone left behind after breakouts. It gently clears away surface buildup, which may improve the look of dark marks and support a smoother, more even complexion over time.
Sources: [Dermatologic Surgery, 2009](https://pubmed.ncbi.nlm.nih.gov/19400885/), [Dermatologic Surgery, 1999](https://pubmed.ncbi.nlm.nih.gov/9935087/)

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

This serum goes in the evening routine, as treatments with active ingredients are placed at night for simplicity and extra safety around sun exposure. A product of this type for skin with dark spots needs ingredients that lighten dark spots and gentle exfoliants, along with rich softening ingredients for optimal nourishment.

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

You can use this treatment in your evening routine, applying it before your moisturizer and keeping retinol for a different night to avoid irritation. This serum works for skin with dark spots, but to be a great fit for your normal skin, it needs extra nourishing, softening ingredients.

### How often should I use this serum?

Apply this serum in your evening routine, starting just once a week and gradually using it more often if your skin handles it well. This routine timing keeps things simple and extra safe around sun exposure, while ingredients like Thiamidol work over time to help fade dark spots. Skin with dark spots of this type also needs soothing and softening ingredients for rich nourishment.

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

This serum is unlikely to clog pores or cause breakouts on your skin with dark spots, as it contains salicylic acid which helps keep pores clear. However, because it gently exfoliates, you might experience mild purging when you first start using it.
Sources: [International Journal of Cosmetic Science, 2021](https://pubmed.ncbi.nlm.nih.gov/33559186/)

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

It contains fragrance (parfum) and drying alcohol (alcohol denat).
