## Questions and answers

### What makes Peter Thomas Roth Even Smoother Glycolic Retinol Resurfacing Serum a great fit for skin with dark spots?

This serum is a great fit for skin with dark spots because it combines high concentrations of glycolic acid and retinol to promote cell turnover and fade pigmentation. Niacinamide further helps reduce dark spots by stopping pigment transfer, while soothing ingredients like allantoin and panthenol keep your skin comfortable.
Sources: [The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/)

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

Glycolic acid and retinol are the main ingredients that make this serum a great fit for dark spots because they work together to speed up cell turnover and fade discoloration. Niacinamide also helps by improving skin lightness and reducing dark patches.
Sources: [The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/)

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

Glycolic acid helps fade dark spots by gently removing dull surface layers to reveal a more even tone. This ingredient is unlikely to cause major irritation when used as directed, making it a helpful addition to routines targeting stubborn discoloration.
Sources: [Dermatologic Surgery, 2017](https://pubmed.ncbi.nlm.nih.gov/28114204/), [The Journal of Dermatology, 2007](https://pubmed.ncbi.nlm.nih.gov/17204097/)

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

Retinol helps fade dark spots and uneven pigmentation when used consistently as part of a skincare routine. It works by encouraging skin renewal, which improves overall tone and smoothness over several weeks.
Sources: [Journal of Drugs in Dermatology, 2016](https://pubmed.ncbi.nlm.nih.gov/27050703/), [Journal of Drugs in Dermatology, 2016](https://pubmed.ncbi.nlm.nih.gov/27391637/)

### 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 toning, followed by your moisturizer. It is well-suited for skin with dark spots because glycolic acid and retinol promote cell turnover and fade pigmentation, while niacinamide and ceramides support the skin barrier.
Sources: [Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38406974/)

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

You can use this serum with BHA, but it is best to apply them on alternate nights or separate them into different routines to minimize the risk of irritation. Combining strong exfoliants like glycolic acid and retinol with BHA at the same time may cause excessive dryness or redness on your skin.

### How often should I use this serum?

Start by using this treatment once a week in the evening, and if your skin tolerates it well without irritation, you can carefully use it more often. This gradual approach helps your skin adjust to active ingredients like glycolic acid and retinol while minimizing discomfort.
Sources: [Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38406974/), [The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/)

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

This serum is a great fit for skin with dark spots, and while it helps fade spots by speeding up cell turnover with glycolic acid and retinol, that same process may occasionally cause initial breakouts or purging. Reviewers rarely report breakouts from this formula, and soothing ingredients like niacinamide and panthenol help keep your skin comfortable.
Sources: [The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/)

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

It has no fragrance and contains drying alcohol (alcohol).
