This fit is calculated for the concerns frequently associated with oily acne-prone skin: shine, breakouts, blemishes, and enlarged pores. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for oily acne-prone skin; other products fit it better.

## Why this fit

- Offers moderate exfoliation for your oily skin, as R-Bacillus Licheniformis Keratinase and pineapple fruit extract effectively smooth texture and promote shedding of corneocytes.
- While cellulose and glycerin provide hydration, these ingredients offer general skincare benefits that are mostly supportive and not directly targeted at your acne, blemishes, and breakouts.
- The product is safe for your oily skin with no risks of irritation due to the absence of prohibited or harsh ingredients.

- Ten days of treatment with a cream containing 20% glycerin significantly increased skin hydration measured by corneometer values in 17 healthy volunteers compared to a placebo cream, but showed no influence on transepidermal water loss or skin sensitivity to an irritating surfactant. ([International Journal of Cosmetic Science, 2001](https://pubmed.ncbi.nlm.nih.gov/18498456/))
- Topical application of 0.1% hyaluronic acid formulations of different molecular weights led to significant improvements in skin hydration and elasticity, with low-molecular-weight formulations also significantly reducing wrinkle depth in seventy-six female subjects compared to a vehicle control. ([Journal of Drugs in Dermatology, 2011](https://pubmed.ncbi.nlm.nih.gov/22052267/))
- Topical application of hyaluronic acid in conjunction with free gingival graft significantly reduced donor site postoperative pain until day 7 compared to normal saline, with no significant differences in graft dimensions or patient satisfaction.

- Enzymatic exfoliation using the keratinase HT1 efficiently decomposed human skin keratin and exfoliated the outermost stratum corneum with less abrasiveness and no damage to the epidermal layer compared with chemical exfoliation. ([Enzyme and Microbial Technology, 2025](https://pubmed.ncbi.nlm.nih.gov/39970752/))

## Why other products fit oily acne-prone skin better

- Adapalene 0.1%-benzoyl peroxide 2.5% fixed-dose combination gel provided significantly greater, synergistic efficacy and a faster onset of action compared with the vehicle, adapalene monotherapy, and benzoyl peroxide monotherapy in patients with acne vulgaris. ([The British Journal of Dermatology, 2009](https://pubmed.ncbi.nlm.nih.gov/19466959/))
- Topical benzoyl peroxide 5% gel treatment improved acne severity, sebum, stratum corneum hydration, and transepidermal water loss, while significantly reducing microbial diversity and the prevalence of Cutibacterium in 33 patients with acne vulgaris.

## What reviewers say

Based on a very large amount of data, this product is highly praised for its gentle, acid-free enzymatic exfoliation that effectively removes dead skin cells without causing irritation, making it ideal for sensitive, dry, and combination skin. Users consistently report that it leaves their complexion feeling baby-soft, smooth, and radiant, while helping to unclog pores and improve overall skin texture. Some users question the efficacy of the visible 'rolling' effect, suggesting it may be due to the cellulose ingredient rather than actual dead skin removal.

- Liked: Gentle exfoliation (mostly mentioned)
- Liked: Leaves skin soft (mostly mentioned)
- Liked: Removes dead skin (often mentioned)
- Liked: Brightens complexion (sometimes noted)
- Disliked: Cellulose gimmick (sometimes noted)
- Disliked: Can cause breakouts (rarely noted)
- Disliked: Difficult to rinse (rarely noted)
- Disliked: High price (rarely noted)

## How to apply

- Use this exfoliant as part of your PM routine once a week to start, increasing frequency only if your skin tolerates it well.
- Apply the exfoliant after cleansing and toning, but before your final moisturizer step.
- Gently press 2-3 drops of the exfoliant into your skin and let it absorb for a minute.
- Apply the product directly onto clean, dry skin for the best results against breakouts.
- Avoid the sensitive eye area and always use a daily SPF since exfoliating makes skin more sensitive to the sun.

## Questions and answers

### How well does Peter Thomas Roth FIRMx Peeling Gel work for oily acne-prone skin?

This exfoliant treatment works moderately well for your oily skin, smoothing texture and helping shed dead cells without causing irritation, though it lacks direct blemish-fighting ingredients. An exfoliant for this skin type needs targeted blemish fighters like niacinamide or benzoyl peroxide, along with oil-controlling and soothing ingredients that manage breakouts while keeping skin comfortable.
Sources: [European Journal of Pharmaceutics and Biopharmaceutics, 2014](https://pubmed.ncbi.nlm.nih.gov/23973717/)

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

R-Bacillus Licheniformis Keratinase and pineapple fruit extract make this exfoliant a good fit for your oily skin by smoothing texture and helping shed dead cells. Glycerin and cellulose provide hydration, but an exfoliant of this type needs ingredients like niacinamide, propolis, benzoyl peroxide, or Vitamin C to actively target breakouts and manage excess oil for this skin.
Sources: [European Journal of Pharmaceutics and Biopharmaceutics, 2014](https://pubmed.ncbi.nlm.nih.gov/23973717/)

### What does Pineapple Extract do for oily acne-prone skin?

Pineapple extract helps balance oily skin and keeps pores clear by reducing excess oil and calming redness. It is unlikely to irritate sensitive acne-prone skin while providing these clarifying benefits.

### What do Pomegranate Enzymes do for oily acne-prone skin?

Pomegranate Enzymes help clear away dead skin and oil that can clog pores, leaving oily acne-prone skin feeling smooth and looking clearer. This gentle exfoliation helps reduce breakouts without causing dryness or irritation.

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

This exfoliant treatment goes in the evening routine once a week to start, as routines begin exfoliating steps slowly and use treatments at night for safety around sun exposure. This product works for oily skin by smoothing texture, but oily acne-prone skin also needs ingredients that directly target breakouts and blemishes.

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

You can use this treatment with retinol by applying the exfoliant first to smooth texture, waiting for it to dry, and then following with your retinol on separate nights or spaced out in your routine to help prevent irritation. This product offers moderate exfoliation for oily skin, but to better fit acne-prone skin, it needs ingredients that directly target breakouts and blemishes.

### How often should I use this exfoliant?

Start using this exfoliant treatment once a week, and if your oily acne-prone skin tolerates it well and shows good results, you can carefully use it more often. While it helps smooth texture, this skin also needs targeted ingredients for breakouts and blemishes.

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

This exfoliant is unlikely to cause breakouts or clog pores on your oily skin because it has a very safe formula with no harsh ingredients. However, a product for this skin needs targeted blemish-fighting ingredients to actively manage breakouts, which this gel mostly lacks.
Sources: [European Journal of Pharmaceutics and Biopharmaceutics, 2014](https://pubmed.ncbi.nlm.nih.gov/23973717/)

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

Yes, it has no fragrance and no drying alcohol.
