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

Works for dry sensitive skin; other serums fit it better.

## Why this fit

- Offers moderate exfoliation and texture improvement for your dry and sensitive skin due to glycolic acid and retinol, which help minimize fine lines and wrinkles. Humectants like Propanediol and barrier-repairing ingredients such as Squalane and Ceramide NP provide some hydration and support, but the formula lacks sufficient emollient and occlusive agents to fully address dryness.
- The serum provides general skincare benefits like hydration and soothing, which you would notice, but these are mostly supportive for your dry or flaky skin and sensitivity.
- The safety profile is excellent, with no risks of irritation for your dry and sensitive skin due to the absence of prohibited or harsh ingredients.

## Why other serums fit dry sensitive skin better

- A formulation containing glycerol (5%) and xylitol (5%) applied twice daily for 14 days increased skin hydration, filaggrin protein quantity, interdigitation index, and biomechanical properties, and decreased transepidermal water loss compared to untreated and vehicle-treated skin in twelve volunteers with dry skin.

## How to apply

- Use this PM routine for your evening skincare. Start using the serum 3 times a week and increase to daily use if your skin feels comfortable.
- Apply the serum after cleansing and toner, but right before your moisturizer. This step locks in deep hydration for dry skin.
- Gently press 2-3 drops of the serum into your skin using your palms. Let it absorb completely for a minute ⏱ before applying your next product.
- Since your skin is sensitive, apply the serum on completely dry skin for better tolerance and less irritation.
- Avoid the sensitive eye area during application. Always do a patch test before your first use to ensure your skin reacts well.

## Questions and answers

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

This serum works moderately well for dry and sensitive skin, providing some hydration and texture improvement while carrying a very low risk of irritation. However, because it lacks sufficient rich softening and sealing agents, a product of this type needs added heavy moisturizers, barrier-supporting lipids, and soothing ingredients to fully lock in moisture and protect dry skin.
Sources: [International Journal of Cosmetic Science, 2024](https://pubmed.ncbi.nlm.nih.gov/37699769/)

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

Propanediol, squalane, and ceramide NP help make this serum a fit for dry sensitive skin by providing hydration and supporting the skin barrier. A treatment of this type needs rich moisturizing ingredients like ceramides and heavy soothing oils to fully comfort and protect dry skin.
Sources: [International Journal of Cosmetic Science, 2024](https://pubmed.ncbi.nlm.nih.gov/37699769/)

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

Glycolic acid can be too harsh for dry sensitive skin because it speeds up skin shedding and may increase water loss. Skin of this type needs gentle hydrating ingredients and soothing agents to keep it smooth and calm without irritation.
Sources: [Acta Dermato-venereologica, 1995](https://pubmed.ncbi.nlm.nih.gov/8651024/), [The British Journal of Dermatology, 1997](https://pubmed.ncbi.nlm.nih.gov/9470910/)

### What does Retinol do for dry sensitive skin?

Retinol is typically too harsh for dry sensitive skin because it easily triggers irritation and redness. Skin of this type needs gentle, hydrating ingredients like glycerin and hyaluronic acid, along with soothing agents, to strengthen the skin barrier while smoothing lines.
Sources: [Toxicology Letters, 2003](https://pubmed.ncbi.nlm.nih.gov/14615068/), [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

This treatment goes in the evening routine after your toner and before your moisturizer. A product of this type for dry sensitive skin needs rich nourishing ingredients and barrier-protecting oils and butters to lock in hydration and prevent dryness.

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

You can use this serum with BHA, but because both ingredients exfoliate, using them together may easily cause irritation on dry and sensitive skin. To stay safe, use them on alternate nights or apply the BHA first, let it absorb completely, and follow with a rich moisturizer containing heavy softening and barrier-protecting ingredients to lock in hydration.

### How often should I use this serum?

Start using this treatment once a week in the evening, and if your dry and sensitive skin tolerates it well and sees good results, you may carefully use it more often. A product of this type needs rich moisturizing oils and heavy protective barriers to fully comfort and soften this skin type.
Sources: [Facial Plastic Surgery, 2014](https://pubmed.ncbi.nlm.nih.gov/24488631/)

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

This serum is unlikely to cause breakouts, as reviewers report such issues in very few cases and the product has a very safe profile. However, it may cause mild purging when you first start using it because it contains exfoliating ingredients like glycolic acid and retinol.
Sources: [International Journal of Cosmetic Science, 2017](https://pubmed.ncbi.nlm.nih.gov/27261203/)

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

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