## What reviewers say

Based on a very large amount of data, this serum is highly rated by users with oily, acne-prone, and textured skin for its ability to rapidly reduce breakouts and smooth skin surface. While effective for many in clearing congestion and tightening pores, a notable minority of users experience purging, stickiness, or irritation due to its potent acid blend.

## 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.

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

This serum is a great fit for oily skin because it contains glycolic acid and salicylic acid, which exfoliate the skin and clear out pores to help control oily shine. Ingredients like niacinamide and capryloyl salicylic acid support this by refining skin texture and helping to manage oil.
Sources: [Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/33617668/), [Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/37941097/)

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

Glycolic acid helps clear away dead skin and excess oil for a smooth, clean feel. It gently removes buildup from the surface, which keeps pores clear and skin looking fresh.
Sources: [Molecules, 2023](https://pubmed.ncbi.nlm.nih.gov/37894698/), [Journal of the European Academy of Dermatology and Venereology, 2011](https://pubmed.ncbi.nlm.nih.gov/21029205/)

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

Salicylic acid helps oily skin by reducing excess oil and keeping pores clear. It may also improve overall skin hydration while managing breakouts.
Sources: [Journal of Cosmetic Dermatology, 2025](https://pubmed.ncbi.nlm.nih.gov/40682377/), [Experimental Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/30972839/)

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

This serum goes in the evening routine after cleansing and before moisturizing, starting at once a week. You may use it more often if your skin tolerates it well and shows good results.

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

You can use this treatment with retinol by applying it in your evening routine, but use them on alternate nights to keep your skin calm and smooth. Because both products work hard to renew your skin, alternating them helps prevent dryness and irritation.
Sources: [Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/33617668/), [BioMed Research International, 2020](https://pubmed.ncbi.nlm.nih.gov/33150170/)

### How often should I use this serum?

Start by using this serum once a week in your evening routine, and if your skin handles it well, you can carefully use it more often. This gradual approach helps you monitor your skin while managing oily shine and refining texture with glycolic acid and salicylic acid.
Sources: [Dermatologic Surgery, 2003](https://pubmed.ncbi.nlm.nih.gov/14725662/), [Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/32356917/)

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

This exfoliant treatment helps clear pores and control oily shine using glycolic acid and salicylic acid. It is unlikely to cause irritation, but some reviewers report initial breakouts as the acids work to clear out the skin.
Sources: [Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/33617668/), [Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/37941097/)
