There’s a certain amount of science involved when it comes to building the perfect skincare regimen. Some products are better kept separate, unless you’re actively looking for irritation. But did you know there are a few powerful skincare ingredients that can be mixed and layered without causing negative reactions? Read on.
1. Hyaluronic Acid + Hydroxy Acids
Hyaluronic acid functions as a “humectant” and is a great follow-up to chemical exfoliating ingredients like AHAs and BHAs because they clear pores and pave the way for all the hydration you get from the hyaluronic acid.
2. Vitamin C + Vitamin E
Vitamin C works as an antioxidant to stop the free radicals that trigger wrinkling, sagging, and other aging changes. Like vitamin C, vitamin E’s main function in skin care is to protect against sun damage. Combined, they provide 4x more protection against free radicals.

3. Hyaluronic Acid + Retinol
Both of these ingredients are powerful anti-agers so using them together can really amp up their effectiveness. A study published in 2011 Journal of Cosmetic Dermatology found that using retinal and hyaluronic acid together significantly improves overall photoaging, ptosis and hyper-pigmentation.
4. AHAs + BHAs
According to a 2009 study, AHAs and BHAs yield fuller skin when used together. To make them work together, either use AHAs and BHAs on alternating days, or you can apply an AHA to dry areas and a BHA to oily areas of your skin.
5. Sunscreen and All of the Above
Since retinol, AHAs, salicylic acid, etc. can all cause increased sun sensitivity, don’t forget to apply a broad-spectrum (SPF 30+ ) sunscreen to protect the new healthy skin that is being created. The key is to layer the sunscreen OVER the product with active ingredients.
