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 suitability for your combination skin, as Glycerin and Macadamia Ternifolia Seed Oil provide hydration and emollient benefits, while Retinal and Bakuchiol offer anti-aging effects. The formula includes soothing Panax Ginseng Root Extract and Bakuchiol, which are beneficial for your skin's sensitivity.
- Niacinamide and Glycerin support your skin's barrier function and provide moisture, which is helpful for acne and breakouts, though the product may not offer optimal oil control for your combination skin.
- The product is safe for your combination skin, with no risks of irritation due to the absence of harsh ingredients and the inclusion of soothing components.

## Questions and answers

### How well does K-SECRET Retinal Serum work for acne-prone skin?

This serum works moderately well for acne-prone skin, providing helpful moisture and soothing plant extracts while lacking optimal oil control. Acne-prone skin needs ingredients like niacinamide and zinc PCA to target breakouts and control oil while keeping skin balanced.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

This serum works for acne-prone skin because Niacinamide and glycerin support the skin barrier and provide moisture. To fit this skin type best, a product also needs ingredients like propolis or zinc PCA that help control oil while keeping skin balanced.

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

Retinal helps clear acne-prone skin by reducing blemishes, clogged pores, and redness while improving overall skin texture. Side effects are very uncommon when using this ingredient.
Sources: [International Journal of Cosmetic Science, 2026](https://pubmed.ncbi.nlm.nih.gov/42572367/), [Clinical and Experimental Dermatology, 1999](https://pubmed.ncbi.nlm.nih.gov/10564319/)

### What does Ginseng Root Extract do for acne-prone skin?

Ginseng Root Extract helps acne-prone skin by reducing oxidized sebum, calming redness, and fighting blemish-causing bacteria. This ingredient may improve early to middle-stage acne symptoms while supporting skin barrier repair and reducing inflammation.
Sources: [Journal of Cosmetic Dermatology, 2025](https://pubmed.ncbi.nlm.nih.gov/40762221/), [Phytotherapy Research, 2019](https://pubmed.ncbi.nlm.nih.gov/30506753/)

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

This serum goes in the evening routine after cleansing and before moisturizing, as Lovi routines put treatments in the evening for simplicity and extra safety around sun exposure. Because this product offers an average fit for acne-prone skin, a product of this type needs stronger oil control and pore-clearing ingredients to manage breakouts more effectively.

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

This serum works for your acne-prone skin, though other products fit it better because this formula may not offer optimal oil control. To use it with an AHA, alternate nights or apply your AHA in the morning and this treatment at night to help prevent irritation. Acne-prone skin of this type needs targeted oil-balancing ingredients and lightweight hydrators to keep breakouts clear and skin balanced.
Sources: [Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38102855/), [American Family Physician, 2012](https://pubmed.ncbi.nlm.nih.gov/23062156/)

### How often should I use this serum?

This serum can be used in your evening routine, starting once a week and slowly increasing the frequency if your skin tolerates it well. This gradual approach helps your skin adjust to the active ingredients while keeping irritation unlikely.

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

This serum works for acne-prone skin, though initial breakouts are a low risk with this product. It may help balance skin with soothing ingredients and barrier support, but a product for this skin type typically needs stronger oil control and lightweight, non-clogging hydration.

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

Yes, it has no fragrance and no drying alcohol.
