Works for oily skin; other products fit it better.

## Why this fit

- Offers moderate exfoliation for your oily skin due to lactic acid, which helps smooth texture and balance hydration without exacerbating oiliness, complemented by squalane for emollient action.
- While the serum provides general skincare benefits like hydration and cleansing, its primary function of moderate exfoliation is not directly targeted at reducing oily shine.
- The product is safe for your oily skin, with no risks of irritation from harsh ingredients.

## How to apply

- Use this exfoliant product as part of your PM routine once a week. Start slowly and build up frequency only if your skin tolerates it well.
- Apply the exfoliant after cleansing and toner, but right before your moisturizer.
- Gently press 2-3 drops of the exfoliant into your skin and let it absorb fully. Avoid any harsh rubbing to keep your skin calm.
- Apply the exfoliant directly onto completely dry skin to get the best balance and results. Clean, dry skin helps the product work evenly.
- Always avoid the delicate eye area when applying. Be sure to use a broad-spectrum SPF 30+ daily while using exfoliating acids.

## Questions and answers

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

Biossance Squalane + Lactic Acid Resurfacing Night Serum works moderately well for your oily skin, helping smooth texture and balance hydration without exacerbating oiliness, though it does not directly target oily shine. To work best for oily skin, this type of product needs ingredients like niacinamide that control excess oil and reduce shine while keeping the skin comfortable.

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

Lactic acid helps smooth texture and balance hydration on oily skin without making it greasy, while squalane softens the skin. A product of this type for oily skin needs ingredients like niacinamide, ferulic acid, and zinc PCA to control excess oil and reduce shine.

### What does Squalane do for oily skin?

Squalane helps keep oily skin soft and smooth without feeling heavy, though oxidized forms may sometimes trigger irritation. To work well for oily skin, this type of product needs lightweight, non-clogging ingredients that balance moisture without adding excess grease.
Sources: [The Journal of Investigative Dermatology, 2006](https://pubmed.ncbi.nlm.nih.gov/16778793/)

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

Lactic acid helps manage oily skin by significantly reducing oil production and pore size while improving moisture levels. It supports a clearer and smoother look through gentle surface renewal.
Sources: [Frontiers in Physiology, 2026](https://pubmed.ncbi.nlm.nih.gov/42326996/)

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

Apply this serum in the evening after cleansing and toning, followed by your moisturizer. Because oily skin needs a product that directly targets excess oil and shine rather than just moderate exfoliation, an effective routine for this skin type requires oil-reducing and mattifying ingredients.

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

This serum works for your oily skin, but because it provides moderate exfoliation, it is best used on nights when you do not apply retinol to keep your skin calm and comfortable. To better manage oily shine and reduce oiliness, oily skin needs an exfoliant treatment focused specifically on oil control rather than general texture smoothing.

### How often should I use this serum?

Start by using this serum once a week in the evening, and if your skin handles it well and shows good results, you can carefully use it more often. This approach helps you safely introduce the lactic acid and squalane without causing irritation.

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

This serum is unlikely to cause breakouts for oily skin, as it has a low risk of doing so and is safe for your skin type without harsh ingredients. However, because it is an exfoliant, it may occasionally lead to mild purging as it helps smooth texture.

### 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.
