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

A great choice for acne-prone skin; a few products fit it even better.

## Why this fit

- Offers excellent exfoliation and pore-refining benefits for your acne-prone skin, as glycolic acid and salicylic acid effectively decongest pores and target blemishes. Niacinamide further supports skin clarity and helps regulate oil production, making it highly suitable for your combination skin type.
- The presence of capryloyl salicylic acid provides a gentler, more targeted exfoliation, complementing the primary acids and enhancing overall efficacy for breakouts.
- The formula is safe for your skin, with no risks of irritation due to the absence of prohibited or harsh ingredients.

## What the research says

- A moisturizer containing licochalcone A, 1,2-decanediol, L-carnitine, and salicylic acid significantly reduced noninflammatory, inflammatory, and total acne lesion counts compared to a vehicle control in Thai patients during a 12-week maintenance phase. ([BioMed Research International, 2020](https://pubmed.ncbi.nlm.nih.gov/33150170/))

([Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/37941097/))
- The use of a salicylic acid-based dermocosmetic significantly reduces the needed quantity of benzoyl peroxide without impacting efficacy in mild to moderate acne, and as maintenance post-benzoyl peroxide allows a significant reduction of acne relapse compared to vehicle.

- Treatment with 2% supramolecular salicylic acid hydrogel resulted in a regression and markedly improvement rate of 51.01% compared to 43.10% for Adapaline gel in patients with mild to moderate facial acne vulgaris, showing no significant difference in efficacy. ([Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38590107/))
- Topical 5% benzoyl peroxide plus salicylic acid achieved the greatest lesion reduction at early 2 to 4 week time points compared to benzoyl peroxide, clindamycin, and combination benzoyl peroxide/clindamycin, while 5% benzoyl peroxide plus salicylic acid and combination benzoyl peroxide/clindamycin showed similar efficacy at 10 to 12 weeks in acne patients.

## 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.

- Liked: Minimizes pores (often mentioned)

## 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.
