Applying salicylic acid to dry skin is the most recommended method by skincare experts. When applied to a clean, dry face, salicylic acid can penetrate effectively without interference from water, which might dilute its strength.
As a general rule, it's always best to apply Salicylic acid after a shower to avoid accidentally washing any of it off with water or steam.
If it's a leave on product like a toner or serum it just means once applied the salicylic acid will be absorbed into the skin and left there. No need to wash off.
Salicylic acid can be drying to the skin, so it's important to moisturize your skin after using it. Look for a moisturizer that is lightweight, non-comedogenic, and free of fragrances and other irritants. Moisturizing after using salicylic acid can help to soothe the skin and prevent dryness and irritation.
Retinoids or retinol and salicylic acid
Generally, it's recommended you don't mix retinol and salicylic acid in your skincare routine due to the risk of redness or potentially irritating side effects [3].
Avoid the eye area and any open wounds or inflamed skin. Wait for the salicylic acid to fully absorb into the skin. This usually takes about 2-3 minutes. Apply your moisturizer to help hydrate the skin and lock in the salicylic acid.
How long should I leave salicylic acid cleanser on my face? This can vary depending on how much time you take to cleanse your skin. For many, the 60 second rule has proven to be the most effective.
If you've recently started using a product containing retinoids or chemical exfoliants such as glycolic or salicylic acid, there's a good chance your skin is feeling the purge. These ingredients work quicker by helping bring impurities to the surface and small red bumps can actually be a sign the product is working.
Can you leave salicylic acid on your face overnight? Yes, you really can! You can use salicylic acid twice a day if required, those with a skin type that is oily and prone to breakouts will benefit from using the BHA most.
Two non-prescription active ingredients that your dermatologist may recommend for treating acne are salicylic acid and benzoyl peroxide.
Wipe the pad gently onto the skin to apply the medication, usually 1 to 3 times a day or as directed by your doctor. Wash hands after use. If using cleansers containing salicylic acid, wet the affected area. Gently rub the cleanser into the skin for 10 to 20 seconds, or as directed.
The exfoliating abilities of salicylic acid might aggravate dryness by removing the skin's natural oils. Individuals with dry skin should instead concentrate on moisturising their skin using hyaluronic acid, ceramides, and glycerin-containing products.
There are several reasons retinol and salicylic acid should not be used at the same time. Since retinol is such a potent ingredient, it already creates the potential for temporary dryness, redness and flaking. When applied at the same time with salicylic acid, the chances of these effects are increased.
Also, do not use this medicine if you are a diabetic or if you have poor blood circulation. Do not use this medicine on warts with hair growing from them or on warts on the face, in or on the genital (sex) organs, or inside the nose or mouth. Also do not use on moles or birthmarks. To do so may cause severe irritation.
When purging your skin, you'll typically see blackheads and small, flesh-coloured bumps rather than inflamed pustules, nodules or deeper cysts. But this is not an absolute rule. Overall, acne caused by skin purging often tends to appear and then disappear much faster than classic breakouts.
Salicylic acid may produce mild side effects, such as skin irritation or peeling. If people experience more severe side effects, they should stop using the product and contact their doctor. When using salicylic acid or other acne treatments, it may take 6-8 weeks to start noticing results.
"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 has salicylic acid in the formula, Dr. Hu advised only using the product three times per week to avoid over-exfoliating the skin and drying it out.
There can always be too much of a good thing and salicylic acid is no different. The main negative side effect when overused is it can irritate and cause excess dryness. If you have sensitive skin, choose your formula carefully as some products contain denatured alcohol, which can be additionally drying.
After applying salicylic acid, don't forget to follow up with a hydrating moisturizer.
Applying salicylic acid to dry skin is the most recommended method by skincare experts. When applied to a clean, dry face, salicylic acid can penetrate effectively without interference from water, which might dilute its strength.
You may increase up to 15 minutes if you experience no irritation. To neutralise the acid (to stop it working) rinse well with plenty of lukewarm water (not hot). If after leaving for 15 minutes you have no problems, you may use overnight under a moisturiser, but we do recommend rinsing to avoid over exfoliation.
