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

Works for mature skin; other products fit it better.

## Why this fit

- Offers moderate exfoliation for your normal skin due to lactic acid, which helps regulate desquamation and smooth texture, while squalane provides emollient action.
- While the formula is safe and hydrating for your normal skin, the concentration of lactic acid is not significant enough to provide substantial resurfacing for your wrinkles and fine lines.
- The product is safe for your normal skin, with squalane offering soothing benefits and no harsh ingredients present.

## Questions and answers

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

Biossance Squalane + Lactic Acid Resurfacing Night Serum works moderately well for mature skin, providing gentle smoothing and hydration, but the lactic acid concentration is not significant enough to substantially target fine lines and wrinkles. Mature skin needs an exceptionally safe product that effectively targets wrinkles with high-quality anti-aging ingredients, rich in antioxidants, peptides, and humectants to improve elasticity and moisture retention.
Sources: [Scientific Reports, 2020](https://pubmed.ncbi.nlm.nih.gov/33037252/), [Molecules, 2025](https://pubmed.ncbi.nlm.nih.gov/40363772/)

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

Lactic acid and squalane make this serum a fit for mature skin by helping smooth texture and keep it soft with moisture. Because this product is an average fit, an exfoliant treatment for mature skin needs powerful anti-aging ingredients like high-quality antioxidants, peptides, and humectants to effectively target fine lines and improve elasticity.
Sources: [Scientific Reports, 2020](https://pubmed.ncbi.nlm.nih.gov/33037252/), [Molecules, 2025](https://pubmed.ncbi.nlm.nih.gov/40363772/)

### What does Squalane do for mature skin?

Squalane helps keep mature skin feeling soft and smooth by boosting moisture and protecting the skin barrier. It also provides antioxidant support that helps improve the look of fine lines and wrinkles over time.
Sources: [Journal of Nanobiotechnology, 2025](https://pubmed.ncbi.nlm.nih.gov/40001122/), [Journal of Nanoscience and Nanotechnology, 2010](https://pubmed.ncbi.nlm.nih.gov/21137794/)

### What does Lactic Acid do for mature skin?

Lactic acid helps mature skin by boosting firmness and smoothing out rough texture through increased collagen production. It also helps lock in moisture and brightens dark spots for a more youthful appearance.
Sources: [International Journal of Biological Macromolecules, 2024](https://pubmed.ncbi.nlm.nih.gov/39102921/), [Frontiers in Medicine, 2021](https://pubmed.ncbi.nlm.nih.gov/33681250/)

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

This serum goes in the evening routine after cleansing and before moisturizing, starting once a week and using it more often if tolerated well. Mature skin needs stronger treatments with higher concentrations of active ingredients like lactic acid to effectively smooth fine lines and wrinkles.

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

This serum is safe to use on your mature skin, but layering it with a strong retinol may easily cause irritation. When using both in the evening, apply this lactic acid treatment first, let it absorb, and follow with your moisturizer before adding a retinol on alternate nights.

### How often should I use this serum?

Start by using this treatment once a week in your evening routine, and carefully increase the frequency if your skin tolerates it well and sees good results.

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

This serum is unlikely to cause breakouts or clog pores on mature skin since it has a safe formula with low user complaints and soothing squalane. However, because it contains lactic acid, it may cause mild skin clearing or irritation when you first start using it.

### 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.
