No matter how much you know about skin care, the word “acid” can undoubtedly cause some concern. So when it comes to mixing, applying, and using these acids, it can be a little daunting, especially when it comes to figuring out the best order to use different skin care products.
So, with that in mind, let’s take a look at whether lactic acid can be used after a salicylic acid mask.
Can salicylic acid and lactic acid be used together?
Yes, it is considered safe to use salicylic acid and lactic acid together because they work on different areas of the skin and can target different skin concerns, so they won’t cause irritation or allergic reactions. Both ingredients are chemical peel ingredients that are very effective for achieving a variety of skin effects.
Fortunately, salicylic acid and lactic acid can be used together because of their different molecular sizes. Lactic acid is considered the gentlest of the chemical exfoliating acids, called alpha hydroxy acids (AHAs). This is because its molecular size is very large and it can’t penetrate too deeply into the skin.
Salicylic acid, on the other hand, has a smaller molecular size and is also oil-soluble. This means that it can reach the lower layers and clear the pores of excess sebum, dirt, bacteria, and other impurities.

What should you use after a salicylic acid mask?
Knowing the best order to apply your skincare products can ensure you get the most out of your powerful formulas packed with active ingredients.
You might think that applying a mask at the end of your skincare routine provides the best skin results. In fact, after cleansing your skin, you should apply your mask before the rest of your routine, especially if it contains salicylic acid.
Below is an example of an evening skincare routine that you can adapt to your needs.
Evening Skincare Routine
Cleanser – Removes all traces of makeup and the day’s impurities. For your evening routine, you can also double cleanse to ensure your skin is thoroughly cleansed. Don’t forget to combine your cleanser with a washcloth for best results.
Mask (Best) – Masks should be applied to cleansed skin between the other steps of your skincare routine. Generally, it’s best to use a mask once or twice a week.
Toner – If you’ve already used a salicylic acid-rich mask, you can skip this step. Choose a toner that is rich in PHA or lactic acid to avoid irritating your skin.
Serum – One that contains hyaluronic acid or other humectants to provide extra moisture to the skin.
Oil – This is another best step if you want to recharge your skin overnight. Choose a formula with plant extracts to nourish and regenerate the skin.
Moisturizer – Lock in all the benefits of the previous steps with a layer of moisturizer. In the morning, your skin will appear refreshed, rejuvenated, and revitalized.

Which is Stronger, Salicylic Acid or Lactic Acid?
Of the two acids, salicylic acid is considered stronger and is most beneficial for people with combination, oily, or blemish-prone skin. You’ll find salicylic acid as one of the most commonly used BHAs, often included in effective skincare formulas to fight blemishes, spots, and acne.
Because salicylic acid is related to aspirin, it has anti-inflammatory properties and works to exfoliate the outer surface of the skin. Accumulated dead skin cells, impurities, and bacteria are eliminated, leaving skin clear and refreshed, while salicylic acid also penetrates the underlying layers to open up the pores.
As for lactic acid, this is an AHA known for its gentle effects and is a popular chemical peel for those prone to dryness and light skin. Sensitivity. This is because, as I mentioned before, lactic acid has a very large molecular size, which means it only works on the outer surface of the skin.
As a result, cases of skin irritation are very rare, but it’s still important to do a 24-hour patch test before applying a cream to your entire face. Moisturizer before salicylic acid?
You’ll find salicylic acid in a variety of skin care products, from face washes to serums to essential oils. This can lead to applying salicylic acid to the skin before moisturizer, but if you’re still having issues, just remember the best order to apply moisturizer.
Skin care products should start with the thinnest consistency and gradually move to the thickest. This ensures that active ingredients and formulas can work without encountering the physical hindrance of thick product textures.
How often should a salicylic acid mask be used?
Due to the generally high levels of salicylic acid in masks, it is best to use it only once or twice a week, if necessary. Overuse of formulas containing high amounts of salicylic acid can make the skin dry, tight, and uncomfortable.
You may also notice that the skin barrier is deprived of sebum (the natural oil in the skin), causing the skin to produce too much sebum, which over time can lead to breakouts and acne.
