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.

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

## Why this fit

- Offers moderate exfoliation and brightening for your combination skin, as Glycolic Acid and Willow Bark Extract help regulate melanogenesis alongside Alpha Arbutin and Kojic Acid. This combination addresses skin tone concerns effectively.
- While the serum provides general hydration and soothing benefits from ingredients like Aloe Barbadensis Leaf Juice and Glycerin, it lacks sufficient concentrations of targeted acne-fighting ingredients like salicylic acid to significantly improve your blemishes and breakouts.
- The product is safe for your combination skin, with no risks of irritation due to the absence of prohibited or harsh ingredients.

## Questions and answers

### How well does Seoul Ceuticals Ultra Brightening Kojic Acid Serum work for acne-prone skin?

This serum works moderately well for acne-prone skin by offering helpful brightening and exfoliation, though it lacks strong acne-fighting ingredients like salicylic acid. A treatment for this skin needs effective ingredients like niacinamide, zinc PCA, or propolis to manage breakouts while maintaining balance.

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

This serum works reasonably well for acne-prone skin because glycolic acid and willow bark extract help clear dark spots and even out your skin tone. However, because it lacks enough targeted acne-fighting ingredients, a product for this skin needs effective additions like niacinamide, propolis, or zinc PCA to truly keep breakouts under control while keeping the skin balanced and hydrated.

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

Kojic acid has antimicrobial properties that may help acne-prone skin, but it is primarily used to fade dark spots rather than treat breakouts directly. A product for this skin type also needs soothing ingredients to calm redness and keep pores clear.
Sources: [Biomedicine & Pharmacotherapy = Biomedecine & Pharmacotherapie, 2019](https://pubmed.ncbi.nlm.nih.gov/30537675/), [Experimental Dermatology, 2022](https://pubmed.ncbi.nlm.nih.gov/35960194/)

### What does Alpha Arbutin do for acne-prone skin?

Alpha arbutin is primarily used to fade dark spots and uneven areas rather than to treat acne-prone skin directly. Because it focuses on reducing pigment rather than clearing blemishes or excess oil, acne-prone skin needs ingredients that unclog pores and calm redness, such as salicylic acid or niacinamide, to properly manage breakouts.

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

This serum goes in the evening routine, as treatments with active ingredients are used then for simplicity and extra safety around sun exposure. Acne-prone skin needs products with higher concentrations of targeted blemish-fighting ingredients like salicylic acid to significantly improve breakouts.

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

You can use this serum with retinol by applying this treatment first and following with your retinol. Because this product provides moderate exfoliation, combining it with retinol may increase the likelihood of dryness or irritation on acne-prone skin.

### How often should I use this serum?

This serum can be used in your evening routine, starting just once a week to see how your skin feels. If your skin tolerates it well and you see good results, you can carefully use it more often. To truly improve blemishes and breakouts on acne-prone skin, a product of this type needs higher concentrations of targeted acne-fighting ingredients like salicylic acid.

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

This serum is unlikely to clog pores or cause severe breakouts, but it also lacks enough strong acne-fighting ingredients like salicylic acid to significantly improve blemishes on acne-prone skin. Products of this type need higher levels of dedicated blemish-clearers and soothing helpers to truly clear up acne-prone skin.

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

Yes, it has no fragrance and no drying alcohol.
