This fit is calculated for the concerns frequently associated with dry skin: flakiness, tightness, dehydration, fine lines, and wrinkles. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for dry skin; other serums fit it better.

## Why this fit

- Offers moderate suitability for dry skin as humectants like Propanediol and Squalane provide some hydration, but the inclusion of glycolic acid and retinol in concentrations geared towards resurfacing may not fully address your dry or flaky skin concerns.
- While ingredients like Jojoba Seed Oil and Pumpkin Seed Oil offer nourishment, the formula lacks sufficient emollient and occlusive properties to provide comprehensive moisturization for dry skin.
- The product is safe for your dry skin, with no risks of irritation due to the absence of harsh ingredients and the presence of soothing components like niacinamide and allantoin.

## Questions and answers

### How well does Peter Thomas Roth Even Smoother Glycolic Retinol Resurfacing Serum work for dry skin?

This serum works moderately well for dry skin, as ingredients like squalane and propanediol offer some hydration, but its resurfacing components may not fully address dryness or flakiness. A product for this skin needs rich, deeply nourishing ingredients that target hydration and strengthen the skin barrier with soothing components, ceramides, and peptides.
Sources: [International Journal of Cosmetic Science, 2024](https://pubmed.ncbi.nlm.nih.gov/37699769/), [Scientific Reports, 2020](https://pubmed.ncbi.nlm.nih.gov/33037252/)

### Which ingredients make this serum a good fit for dry skin?

Humectants like propanediol and squalane help keep dry skin hydrated, while jojoba seed oil and pumpkin seed oil provide nourishment. However, a product of this type needs richer softening and sealing ingredients like ceramides, peptides, and barrier-supporting components to fully address dry skin needs.
Sources: [International Journal of Cosmetic Science, 2024](https://pubmed.ncbi.nlm.nih.gov/37699769/), [Scientific Reports, 2020](https://pubmed.ncbi.nlm.nih.gov/33037252/)

### What does Glycolic Acid do for dry skin?

Glycolic acid can make dry skin smooth by helping shed dead surface flakes, but because it tends to dry out the skin further, it needs to be paired with rich hydrating and soothing ingredients.
Sources: [Acta Dermato-venereologica, 1995](https://pubmed.ncbi.nlm.nih.gov/8651024/), [Archives of Dermatological Research, 1997](https://pubmed.ncbi.nlm.nih.gov/9248619/)

### What does Retinol do for dry skin?

Retinol is generally best avoided on dry skin because it tends to cause irritation and increase moisture loss. This type of skin needs soothing ingredients like ceramides and rich hydrators such as glycerin or hyaluronic acid to repair the barrier and keep it soft and comfortable.
Sources: [Dermatology, 1999](https://pubmed.ncbi.nlm.nih.gov/10473963/), [Toxicology Letters, 2003](https://pubmed.ncbi.nlm.nih.gov/14615068/)

### Where does this serum go in a skincare routine for dry skin?

This treatment goes in the evening routine after cleansing and before moisturizing. A product of this type needs rich, nourishing ingredients that soften and lock in moisture to properly care for dry skin.

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

You can use this serum with BHA, but alternate them or use BHA in the morning and this serum at night to avoid overwhelming your skin. Because this serum combines exfoliating acids and retinol, it is best to pair it with rich, deeply nourishing moisturizers containing ceramides and rich butters to keep dry skin soft and smooth.

### How often should I use this serum?

Start using this treatment once a week in the evening, and if your skin feels comfortable and you see good results, you can carefully use it more often. A product of this type for dry skin needs rich oils, butters, and heavy sealing ingredients to deeply soften and lock in moisture.

### Can this serum clog pores, cause breakouts or purging for dry skin?

Peter Thomas Roth Even Smoother Glycolic Retinol Resurfacing Serum is unlikely to clog pores or cause breakouts for dry skin, though reviews show a low chance of breakouts. This product of this type needs rich nourishing ingredients and heavy sealing properties to keep dry skin feeling soft and smooth without causing congestion.

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

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