A great choice for combination skin; a few products fit it even better.

## Why this fit

- Offers excellent exfoliation for your acne-prone combination skin, as glycolic acid and salicylic acid effectively decongest pores and regulate oil production, while niacinamide further supports sebum control.
- The keratolytic action of these acids is well-suited for managing oily shine, and the absence of harsh ingredients ensures a safe experience.
- The product is safe for your combination skin, with no risks of irritation due to the absence of prohibited or harsh ingredients.

## What the research says

- Twice daily application of a multitargeted dermocosmetic cream provided comparable efficacy to benzoyl peroxide 5% gel in reducing inflammatory, non-inflammatory, and total lesions in 150 Caucasian subjects with mild-to-moderate acne over 56 days, while demonstrating superior skin tolerability. ([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. ([Journal of Drugs in Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/38051857/))
- 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.

- 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.

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

Glycolic acid, salicylic acid, and capryloyl salicylic acid make this serum a great fit because they effectively decongest pores and control oily shine on combination skin, while niacinamide helps balance oil production.

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

Glycolic acid helps smooth and brighten combination skin by gently loosening dead surface cells to speed up skin renewal. This ingredient is unlikely to cause irritation when used properly, but it needs a reliable sunscreen during the day since it makes skin more sensitive to the sun.
Sources: [Acta Dermato-venereologica, 1995](https://pubmed.ncbi.nlm.nih.gov/8651024/), [Archives of Dermatological Research, 1997](https://pubmed.ncbi.nlm.nih.gov/9248619/)

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

Salicylic acid helps clear clogged pores and balance oily areas while remaining gentle enough for dry spots on combination skin. It reduces breakouts and oiliness effectively with a low likelihood of irritation.
Sources: [Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/37941097/), [Journal of Drugs in Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/38051857/)

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

This serum goes in your evening routine, applied after cleansing and before your moisturizer. Lovi routines start exfoliating treatments once a week, and you may use them more often if your skin tolerates them well.

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

It is best to use this exfoliating serum and retinol on different nights to avoid irritation. If you do use them together, apply this serum first, let it absorb completely, and follow with your retinol product.

### How often should I use this serum?

Start by using this serum once a week in your evening routine, and if your skin tolerates it well and shows good results, you can carefully use it more often. This gradual approach helps manage oily shine and decongest pores safely while keeping the risk of irritation low.
Sources: [Dermatologic Surgery, 2003](https://pubmed.ncbi.nlm.nih.gov/14725662/), [Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/32356917/)

### Can this serum clog pores, cause breakouts or purging for combination skin?

Yes, this serum may cause initial breakouts or purging on combination skin as the acids clear out congested pores and regulate oil production. Reviewers sometimes report moderate initial breakouts, and multi-acid treatments help manage oily shine while safely renewing 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/)
