## Questions and answers

### How well does La Roche-Posay Pure Niacinamide 10 Serum work for skin with dark spots?

This serum works for skin with dark spots by using niacinamide and phenylethyl resorcinol to offer mild brightening and hydration. Because other products fit this skin better, a treatment of this type needs a blend of effective antioxidants and soothing ingredients for significant dark spot benefits without irritation.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/32783330/)

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

Niacinamide and phenylethyl resorcinol make this serum a good fit for dark spots by helping fade discoloration and brighten your skin. To better fit dark spots, a product of this type needs a blend of effective antioxidants and soothing ingredients that provide significant benefits for pigmentation.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/32783330/)

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

Niacinamide helps fade dark spots and uneven pigmentation by slowing down the transfer of pigment in the skin. It is generally well tolerated and may improve overall skin brightness with consistent use.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Antioxidants, 2021](https://pubmed.ncbi.nlm.nih.gov/34439563/)

### What does Thermal Water do for skin with dark spots?

Thermal water helps calm and soothe the skin, but it is not a targeted treatment for fading dark spots. Skin with dark spots needs brightening ingredients like vitamin C or niacinamide to help even out skin tone.

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

This treatment serum goes in the evening routine after cleansing and before moisturizing, which keeps things simple and safe around sun exposure. Skin with dark spots works well with treatments that combine targeted brightening ingredients like niacinamide and phenylethyl resorcinol with extra hydrators like glycerin.

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

You can use this serum with retinol by applying the serum first, letting it absorb, and then following with your retinol. Because this product works for dark spots as an average fit, skin with dark spots generally needs targeted brightening ingredients like vitamin C or alpha arbutin alongside stronger pigment-fading agents to achieve the best results.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/32783330/)

### How often should I use this serum?

This serum works well in the evening for your skin with dark spots, though skin with dark spots generally needs targeted brighteners with potent antioxidants and direct pigment inhibitors to get the best results.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/32783330/)

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

This serum is unlikely to cause breakouts for skin with dark spots, as reviews show a low risk and the formula lacks harsh ingredients. However, because this is only an average fit for your skin, darker spots need a treatment with stronger targeted brightening ingredients and antioxidants.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/32783330/)

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

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