## 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. ([BioMed Research International, 2020](https://pubmed.ncbi.nlm.nih.gov/33150170/))
- Dipropylene glycol, propylene glycol, and butylene glycol increased molecular mobility in stratum corneum lipids and affected keratin filaments, with butylene glycol and propylene glycol providing significant permeation enhancement. ([Journal of Controlled Release, 2022](https://pubmed.ncbi.nlm.nih.gov/35150813/))
- Cryotherapy with liquid nitrogen achieved a higher cure rate (39%) than salicylic acid (24%) and a wait-and-see approach (16%) for cutaneous warts at 13 weeks in primary care patients. ([CMAJ, 2010](https://pubmed.ncbi.nlm.nih.gov/20837684/))
- 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. ([Journal of the American Academy of Dermatology, 2010](https://pubmed.ncbi.nlm.nih.gov/20488582/))
- Treatment with a combination of propylene glycol, ethanol, water, and shampoo was found effective, easy to use, and cosmetically attractive with no observed side effects in patients with dandruff. ([Cutis, 1988](https://pubmed.ncbi.nlm.nih.gov/2970946/))
- A moisturizer containing glycerol and propylene glycol reduced transepidermal water loss, decreased epidermal thickness, increased stratum corneum thickness, and reduced dermal inflammatory infiltrate compared to untreated disrupted skin in six healthy beagle dogs.

## Questions and answers

### How well does The Inkey List Beta Hydroxy Acid work for oily skin?

The Inkey List Beta Hydroxy Acid Serum works moderately well for oily skin, as salicylic acid helps manage excess shine and clear pores. However, to truly thrive, oily skin needs products rich in sebum-controlling ingredients like niacinamide and zinc PCA, along with soothing extracts and lightweight hydrators.

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

Salicylic acid makes this serum a good fit for oily skin by helping manage excess sebum and decongest the pores. To fit this skin type even better, products of this type need ingredients like niacinamide to control oil, zinc PCA for enlarged pores, and soothing extracts that keep the skin comfortable and glowing.

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

### What does Water do for oily skin?

Water helps keep oily skin hydrated without adding grease or clogging pores. Keeping oily skin properly hydrated may also help balance oil production and reduce unwanted shine.

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

This serum goes in your evening routine, applied after cleansing and before your moisturizer. Oily skin works best with an exfoliant like this used once a week to start, which you can carefully increase if your skin tolerates it well.

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

This serum can be used alongside retinol by applying the serum first to help clear your pores and manage excess shine, then following with retinol once your skin has adjusted. To keep your skin feeling calm and smooth, a product of this type for oily skin needs gentle exfoliating ingredients like salicylic acid combined with hydrating components that prevent dryness.

### How often should I use this serum?

Start using this serum once a week in your evening routine, and if your skin tolerates it well and you see good results, you can carefully use it more often. An oily skin type of fit needs ingredients like salicylic acid to manage excess sebum, decongest pores, and reduce oily shine.

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

This serum is unlikely to clog pores or cause breakouts for oily skin, as salicylic acid helps clear out oil and clear the pores. Oily skin often does better with formulas that combine salicylic acid with soothing ingredients or targeted oil-control agents.
