## What the research says

- Treatment with 45% mandelic acid peel showed nearly equal overall efficacy as 30% salicylic acid peel in patients with mild-to-moderate facial acne vulgaris, but with fewer adverse effects. ([Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31553119/))

## How to apply

- Use this exfoliant PM once a week to start, and gradually increase if your combination skin tolerates it well. Always apply SPF the next morning to protect your clear skin.
- Apply the exfoliant after cleansing and toning, but right before your moisturizer step. This ensures the treatment targets blemishes effectively.
- Gently press 2-3 drops of the exfoliant into your skin without rubbing. Let it absorb for a minute before moving to the next step.
- Apply the exfoliant on clean, dry skin to help control breakouts safely. Since your skin is not sensitive, this dry application method ensures good product absorption.
- Avoid the sensitive eye area and do a patch test before your first use. Do not mix this exfoliant with other strong acids in the same routine.

### Which ingredients make this serum a good fit for acne-prone skin?

Mandelic acid and niacinamide make this serum a great fit for your acne-prone skin by gently smoothing texture and helping regulate oil production. Additionally, soothing ingredients like green tea extract and sodium hyaluronate help keep your skin calm and hydrated.
Sources: [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31553119/), [Journal of the American Academy of Dermatology, 2001](https://pubmed.ncbi.nlm.nih.gov/11209110/)

### What does Mandelic Acid do for acne-prone skin?

Mandelic acid helps clear acne and smooth the skin by gently exfoliating and calming breakouts with fewer side effects than many other acids. It is unlikely to cause heavy irritation, and combining it with other treatments may improve stubborn acne and dark spots even further.
Sources: [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31553119/)

### What does Niacinamide do for acne-prone skin?

Niacinamide helps acne-prone skin by reducing both inflamed and uninflamed breakouts and calming redness. It is also very helpful for keeping oily skin balanced by cutting down on excess oil production, and it is well tolerated by most people.
Sources: [Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38299457/), [Cureus, 2024](https://pubmed.ncbi.nlm.nih.gov/38725769/)

### Where does this serum go in a skincare routine for acne-prone skin?

This serum goes in your evening routine as a treatment step, applied after cleansing and before your moisturizer. You can start using it once a week, and if your skin tolerates it well, you may carefully use it more often.

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

You can use this serum with retinol by applying them on alternate nights or spacing them out to avoid dryness and irritation. Using strong exfoliating acids and retinol together is more likely to cause redness and peeling on acne-prone skin unless you build up tolerance slowly.

### How often should I use this serum?

Start by using this treatment once a week in the evening, and if your skin tolerates it well with good results, you may carefully use it more often. Chemical exfoliants help smooth texture and manage breakouts, while hydrating and soothing ingredients support overall skin comfort.

### Can this serum clog pores, cause breakouts or purging for acne-prone skin?

This serum is a great fit for acne-prone skin because mandelic acid provides gentle chemical exfoliation to keep pores clear while niacinamide helps regulate oil production. It is unlikely to cause harsh irritation or breakouts thanks to soothing ingredients like green tea extract and sodium hyaluronate.
Sources: [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31553119/)

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