One of the most popular Beta Hydroxy Acids (BHAs), salicylic acid is an ultra-common ingredient in many acne fighting products, and is well-suited for both day and night.
How often should you use salicylic acid? You are able to use salicylic acid twice daily, but only after your skin has built its tolerance. Oily and acne prone skin will benefit from frequent application, however precautionary actions should always be followed when using this potent ingredient.
HOW OFTEN SHOULD YOU USE A SALICYLIC ACID? While the frequency of application will vary from product to product, most will recommend use twice daily.
Having two different cleansers for morning and night sounds unnecessary, but Jaliman says it's good to mix it up. “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.
Use Salicylic Acid in the morning and Retinol at night. Those with more sensitive skin may need to use these products on alternate days, or reduce Salicylic Acid use to once a week or as and when needed.
It is safe to use products with salicylic acid every day, unless it is specified otherwise on the product usage guidelines or by your health care professional. CeraVe's SA Smoothing Cream and SA Smoothing Cleanser are suitable for daily use.
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.
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.
Can I apply moisturizer after using salicylic acid? Yes. Moisturizers can help hydrate and repair skin, making it a good step to do after using an exfoliating treatment with salicylic acid.
"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 get the maximum benefit when you adjust your skin to start using it twice a day. But, if you are sensitive to salicylic acid and using it up regularly left your skin dry, red, and peeling, then use it as a toner and leave it up for up to 30 seconds and then rinse off.
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.
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.
Can I moisturise after salicylic acid? Absolutely, if anything I strongly suggest moisturising after using salicylic acid. Not only will this soothe and calm the skin after applying the potent BHA to your skin.
Wipe the pad over the affected areas. Do not rinse off medicine after treatment.
Yes, you can, BUT you will get better results if you use vitamin C and glycolic acid/salicyclic acid separately. We recommend using vitamin C in the morning and your AHA or BHA at night.
You can test this yourself with a well formulated exfoliant: at night, apply your AHA or BHA as usual after cleansing and toning, and do a "split-test." Wait 20 minutes before applying your serum and/or moisturizer to one side, but the other side of your face, apply those next steps immediately.
Apply 2-3 drops after cleansing & toning. Let the serum absorb fully into the skin before moving on to the next step of your routine. When to use: PM. Start with every alternate day and after 2 weeks of usage, use it everyday.
Using both together will however can become too much for the skin and lead to irritation, rashes, redness, flakiness and all-round discomfort. Much like vitamin C and niacinamide, if you are wanting to use both separate the products completely and apply salicylic acid in the morning and retinol for the evening.
There's certainly no law against using vitamin C products in the evening, but, again, you may get the most benefit from using them in the morning. “In general, vitamin C products should be applied in the morning before heading out for the day, when UV radiation is at its highest,” Dr. Hogan says.
Niacinamide & Salicylic Acid
Niacinamide, a water-soluble form of vitamin B3, and salicylic acid, a beta-hydroxy acid, work particularly well when combined together. Both have anti-aging and anti-acne effects and offer some level of UV protection.
Can niacinamide and salicylic acid be used together? 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.
“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.
