Hyaluronic acid can help rehydrate complexions after a chemical exfoliant like salicylic acid has been applied. This means you can support skin texture and clarity with salicylic acid, followed by hyaluronic acid to nourish and soften the skin.
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].
Retinol and Salicylic Acid
Both of these ingredients are two of the most potent blends in the plethora of skincare products. Combining both of these together will act as a super charged, double intense skin nightmare resulting in severe dryness, sensitivity and an increase in skin photosensitivity.
To support the work of Salicylic acid, bookend its application with a good cleanser and a water-based, non-comedogenic moisturizer. If you've been wearing makeup or SPF, it's best to double cleanse your skin at night – once to whisk away surface-level grime, and second to really get into your pores.
Salicylic Acid + Glycolic Acid
Mixing the two together will strip your skin and most likely cause irritation. Using these acids together can also over exfoliate the skin, which can actually speed up the aging process because it slows cell turnover.
Salicylic acid and niacinamide complement each other and can provide synergistic results when used together. After you cleanse your skin, apply a salicylic acid product. Then, follow that with niacinamide, and finish by moisturizing and adding sun protection.
Using Salicylic Acid with Retinol or Benzoyl Peroxide can dry out the skin, causing flakiness and redness.
Layering of salicylic acid
Always go slow on introducing actives on your skin, go stepwise i.e one at a time. Layering too many products or using too many actives at once is doing more harm than good. Listen to your skin always.
On a little damp skin apply niacinamide serum, and then wait for 1–2 mins for it to totally sink in to your skin. Then go for your salicylic acid serum(ideally in 1 or 2% concentration). Layer it up with a good quality moisturizer according to your skin type.
DON'T MIX: AHA/BHA and niacinamide
Niacinamide is used to treat hyperpigmentation and reduce fine lines and wrinkles, while alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs) are chemical exfoliants. To understand why niacinamide shouldn't be mixed with AHAs and BHAs, you need to consider pH.
The first few days of using salicylic acid to treat your acne may cause the skin to become dry or irritated. To avoid this, use the product lightly at first and gradually increase the amount once you have gotten used to it. Salicylic acid should not be used on broken, red, swollen, itchy, irritated, or infected skin.
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.
What not to mix with Salicylic Acid. Retinol: As Retinol and Salicylic Acid are both exfoliating, drying skincare ingredients, using both together in the same routine could lead to serious irritation.
Use Moisturizer
You should always include a moisturizer in your skincare routine, especially when using an exfoliating ingredient like salicylic acid. This and other cleansing ingredients can strip away the so-called “good oils” that protect your skin and keep it hydrated during the day.
Skin Type Suitability: Salicylic acid is particularly effective for oily and acne-prone skin due to its ability to penetrate and clean out pores. Niacinamide, on the other hand, is suitable for all skin types, including sensitive and dry skin, due to its gentle and soothing properties. 3.
Should you use Salicylic Acid in the morning or night? Salicylic Acid in skincare can be used daily in both morning and in the night. However, when salicylic acid is being used as a part of the AM skincare routine, it is important to end with sunscreen application as the last step of the process.
Should You Use Niacinamide In the AM Or PM? Niacinamide is recommended to be applied up to two times per day. Given this advice, it is typically applied once in the AM and again in the PM before bed. Unlike retinol, niacinamide doesn't increase skin sensitivity and higher chance of reactions from the sun.
Apart from covering off on some different skin concerns, niacinamide and salicylic acid work particularly well together because of the overlapping but complementary effects they have on targeting excess sebum.
