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 products fit it better.

## Why this fit

- Offers moderate exfoliation for your dry skin due to lactic acid, which helps smooth texture, while squalane and glycerin provide general hydration and soothing benefits.
- The formula includes squalane for emollient action, which is moderately suitable for dry skin, but it lacks sufficient humectants to fully address dryness and flakiness.
- The product is generally safe for your dry and sensitive skin, though the presence of lactic acid carries a slight risk of irritation.

## Questions and answers

### How well does Biossance Squalane + Lactic Acid Resurfacing Night Serum work for dry sensitive skin?

Biossance Squalane + Lactic Acid Resurfacing Night Serum works moderately well for dry sensitive skin, offering some smoothing and hydration, but it carries a slight risk of irritation. A product of this type needs maximum beneficial hydrating and nourishing ingredients, ceramides, and multiple forms of vitamin C to provide excellent care without any risk of irritation.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

Squalane and glycerin help smooth and hydrate your dry skin, while lactic acid gently buffs the surface. Because it is only an average fit, an exfoliant treatment for dry sensitive skin needs deep moisturizers and soothing barrier ingredients to keep the skin calm and fully hydrated.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

Squalane helps keep dry sensitive skin soft and smooth by locking in moisture and calming irritation without causing flare-ups. It is unlikely to cause redness or discomfort, making it a gentle choice that supports the skin barrier. This type of skin needs ingredients that deeply hydrate and soothe, such as plant oils and antioxidants.

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

Lactic acid helps hydrate dry skin, but for sensitive skin it may cause stinging and irritation unless it is formulated with soothing ingredients like colloidal oat or tangerine fruit extract to calm discomfort.
Sources: [Journal of Cosmetic Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/36575892/), [Clinical, Cosmetic and Investigational Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/33500646/)

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

This serum goes in the evening routine after cleansing and a soothing toner, followed by a moisturizer. Lovi routines start exfoliating steps like this once a week, and people who tolerate them well and see good results can carefully use them more often. Because your skin is dry and sensitive, a product of this type needs rich hydrators and soothing ingredients to fully address dryness and flakiness while keeping irritation low.

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

It is generally best to avoid using this exfoliating serum in the same routine as retinol, as combining them greatly increases the likelihood of irritation on sensitive skin. Instead, alternate the nights you use each, or use retinol on completely different days to keep your skin calm and smooth.

### How often should I use this serum?

Start using this serum just once a week in the evening, as routines for dry and sensitive skin suggest. If your skin tolerates it well and stays smooth, you may carefully use it more often. A product for this skin needs richer hydrators and soothing ingredients to fully address dryness and flakiness.

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

This serum is unlikely to cause breakouts for dry sensitive skin, though it carries a slight risk of irritation. A product of this type needs richer hydrators and soothing ingredients to fully address dryness and flakiness on sensitive skin.

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

It has no drying alcohol and contains fragrance (linalool). Cetearyl alcohol is a fatty alcohol, which soften the skin.
