Generally, it is not recommended to use a Salicylic Acid cleanser or leave-on exfoliant with Retinol since it can lead to dry skin, leading to other irritation. However, for people with oily acne-prone skin or oily mature skin, the combination can be beneficial.
Applying salicylic acid first will create an exfoliating effect that can help retinol penetrate more effectively into the skin, ensuring that you receive maximum benefits like firming, smoothing and brightening.
“Vitamin A derivatives help to clear acne, as they help to regulate skin cell turnover,” says Marisa Garshick, M.D., a dermatologist in New York City. Unlike salicylic acid, which exfoliates dead skin cells and dissolves clogs, and benzoyl peroxide, which kills acne-causing bacteria, retinoids work from the inside out.
The simple answer is yes. They complement each other well. Being oil soluble, salicylic acid can penetrate deeper into the skin layers, but it can also dehydrate and irritate skin.
"If salicylic acid is an ingredient in your cleanser, it is fine to use it every day." However, if you are using an exfoliant that salicylic acid in the formula, Dr. Hu advises only using the product three times per week, to avoid over-exfoliating the skin and drying it out.
“You can use a salicylic acid–based cleanser in the morning to unclog pores and avoid acne and a glycolic acid–based cleanser at night to exfoliate your skin and get rid of dead skin cells,” notes Jailman.
Retinoids work best if you use them daily. Specifically, they should be used at night because some types are deactivated by light and air. It's important to start slowly and allow your skin time to adjust. Using too much too quickly can cause redness, dryness, and irritation.
Don't Mix: Retinol with vitamin C, benzoyl peroxide, and AHA/BHA acids. AHA and BHA acids are exfoliating, which can dry out skin and cause further irritation if your skincare routine already includes retinol. As for benzoyl peroxide and retinol, they cancel each other out.
Is it safe to use retinol every day? For most people, yes — once your skin is used to it, that is. That said, there are some people who may not want to use it frequently or at all.
Layering products correctly is important if you want your products to work. If you place one product on your skin, like a serum, and follow up with another product whose molecules are smaller than the first, like a toner, then the second product cannot penetrate the first layer.
“To compensate for being overly dry, skin will ramp up oil production, which can create a vicious cycle of dryness and acne,” says Sikora. The fix: Use salicylic in the morning and your retinoid at night.
But overall, stick to using water-based products and serums together. AHAs and BHAs, such as glycolic, salicylic, and lactic acids should never be used with Vitamin C. Vitamin C is an acid, too, and is unstable, so the pH balance will be thrown off by layering these ingredients together and might as well be useless.
Perform the nighttime skincare routine as directed above. After applying retinol to your skin (while it's dry) allow it to sit for 10-20 minutes. Mist your face with water or a facial spray, and then apply your hyaluronic acid. (HA serums are most effective when they're applied to damp skin.)
Don't use with: Although salicylic acid can be combined with other exfoliating ingredients, Mudgil says that in order to avoid irritation, it's best to stick to only one exfoliant at a time.
Salicylic acid may be used morning and night. Because it's so gentle, it may also be applied as a midday spot treatment.
Salicylic acid and vitamin C are both effective products on their own but, when combined, they can be even more beneficial. Whether you're looking to brighten your skin, reduce the likelihood of blemishes or just help slow down the skin's natural aging process, these ingredients may be just what you're looking for.
The best product you can use in conjunction with retinol, according to Dr. Zeichner, is a moisturizer, which can help hydrate skin and reduce the risk of irritation from retinol. “Some people even prefer to mix their retinol with a moisturizing cream to dilute it out,” he says.
Although salicylic acid is considered safe overall, it may cause skin irritation when first starting. It may also remove too much oil, resulting in dryness and potential irritation. Other potential side effects include: skin tingling or stinging.
By using a salicylic acid enriched wash after cleansing the skin of any remaining makeup, you are helping to rid the skin of any dead skin cell build-up allowing any nourishing products applied afterwards to absorb quicker into the lower layers of the skin and show results quicker.
Limit to Two Serums Per Routine
Of course it is fine to use the same one consistently but by alternating you can effectively use many different serums. Retinoids and serums can be used together, especially if the serum is soothing or hydrating. Be careful using very aggressive face oil serums with retinoids.
Norwalk, CT, dermatologist Deanne Mraz Robinson, MD, stresses these ingredients are great when they hit your skin solo, but a definite no-no when applied together. “A mixture of retinoids/retinols with alphahydroxy acids, like glycol, can lead to extreme irritation and redness.”
If you have time, you can use hydroxy acids and retinol sequentially. After applying an AHA or BHA product, wait for 30 minutes to allow your skin's pH to return to normal, and then apply the retinol product.
Rouleau says the best time to use a scrub is in the morning. Overnight you've loosened up dead skin cells with your glycolic acid or retinol products, making the morning a perfect time to brush them off.
Should you use retinol under your eyes? Yes, definitely. While it is true that retinol – a form of vitamin A – is a powerful ingredient and the skin under your eyes is delicate, there's no reason why you should miss out on the amazing benefits of retinol.
