If you have problems with oily or acne, then salicylic acid is your go-to ingredient right next to benzoyl peroxide because of its ability to treat acne, unclog pores, and exfoliate. As a beginner who hasn’t used salicylic acid before, you should start slowly with the lowest concentration of salicylic acid because it can be irritating to the skin.
The lowest concentration ranges in products on the market range from 0.5% to 2% and doing a patch test is highly recommended. In this post, you will learn how to use salicylic acid serum on face as a beginner.
Now let’s get to what salicylic acid truly is, why do dermatologists recommend this golden ingredient for acne and oily skin? I will take you through what salicylic acid is, how to use salicylic acid for beginners in your skincare routine, what to use after salicylic acid, when to use salicylic acid, the best percentage of salicylic acid for beginners and more.
What Is Salicylic Acid?
Salicylic acid is a Beta Hydroxyl acid (BHA) that penetrates deep into the pores of your skin. It works by dissolving the debris that clogs pores, including excess oil, dead skin cells, and impurities. This makes it particularly effective for oily and acne-prone skin, but it can also benefit other skin types when used correctly.
It commonly used as a chemical peel by dermatologists usually at a percentage of 20% – 30%. At this concentration, is used to fade hyperpigmentation, decrease skin roughness and reduce fine lines. But the concentration you will find in over-the-counter ranges from 0.5% to 2% which is also highly effective to unclog pores and increase skin cell turnover making it very useful in acne treatment.
| Salicylic Acid | What this percentage does to the skin |
| 0.5-2% | A gentle formulation that exfoliates the skin, increases cell turnover, unclogs pores, reduces redness and improves skin tone |
| 3-5% | A light peeling product that removes dead skin cells and facilitates penetration of other ingredients into the skin. |
| 10-30% | A peeling agent useful in fading pigmentation, decrease surface roughness and reduce fine lines. |
Salicylic acid is a fat-soluble chemical exfoliant that is originally derived from willow bark trees or wintergreen leaves but nowadays it is mostly synthesized in the lab. It is oil soluble which enables it to penetrate deep into the hair follicles and exfoliate the pores, thereby you start seeing improvements in blackheads, whiteheads and large pores. Salicylic acid also has mild anti-inflammatory and keratolytic properties for people with acne and rosacea.
There was a particular study where low-strength glycolic and salicylic acids were compared for the treatment of blackheads. Scientists compared the efficacy of 8% glycolic acid with 2% salicylic acid for treating blackheads. It was found out that glycolic acid did not decrease the density of the blackhead while salicylic acid did.
Fun Fact:
- Oil-soluble ingredients penetrate deeper into the skin while water-soluble ingredients stay on the skin temporarily and evaporate into the skin.
- Studies show that salicylic acid at 2% is photoprotective and does not increase sun sensitivity meaning it has a profound filter effect when you apply it prior to going out in the sun. Hey, still use your sunscreen!
| Salicylic Acid (BHA) | Glycolic acid, lactic etc (AHA) | |
| Treating Acne | Yes | Yes |
| Useful for dry skin | Maybe | Yes |
| Goes deep into pores | Yes | No |
| Anti-inflammatory | Yes | Maybe |
| Increase cell turnover | Yes | Yes |
| Useful in pregnancy/breastfeeding | No | Yes |
| Boost collagen | No | Yes |
Benefits of Salicylic Acid Serum
- Unclogs Pores: Salicylic acid is oil-soluble, allowing it to penetrate and exfoliate inside the pores, which helps prevent and treat blackheads and whiteheads.
- Reduces Acne: By clearing out clogged pores and reducing inflammation, salicylic acid is effective in treating and preventing acne breakouts.
- Exfoliates Dead Skin Cells: Salicylic acid gently exfoliates the surface of the skin, promoting cell turnover and revealing brighter, smoother skin.
- Reduces Oiliness: It helps regulate the skin’s oil production, making it an excellent choice for those with oily or combination skin.
- Calms Inflammation: Salicylic acid has anti-inflammatory properties, which can help reduce the redness and swelling associated with acne.
How To Use Salicylic Acid Serum In Your Skincare Routine
- Patch Test First: Before applying salicylic acid serum to your entire face, it’s important to do a patch test. Apply a small amount to a discreet area, like behind your ear or on your wrist, and wait 24 hours to ensure there’s no adverse reaction. Start with the lowest concentration of salicylic acid exfoliant and observe your skin response. If there are no irritations within 24 hours of concentration then can start applying it every other day till your skin gets used to this new serum.
- Cleanse Your Face: Start with a gentle cleanser suited to your skin type. This helps remove dirt, oil, and makeup, allowing the salicylic acid serum to penetrate more effectively.
- Apply a Toner (Optional): If you use a toner in your skincare routine, apply it after cleansing. Make sure to choose an alcohol-free toner that won’t dry out your skin.
- Apply Salicylic Acid Serum: Dispense a few drops of the serum onto your fingertips and gently massage it into your face, focusing on areas prone to breakouts or oiliness. Avoid the eye area, as salicylic acid can be too harsh for the delicate skin around the eyes.
- Allow it to Absorb: Give the serum a few minutes to absorb into your skin before moving on to the next step in your routine.
- Follow with Moisturizer: Since salicylic acid can be drying, it’s important to apply a moisturizer after using the serum. Choose a hydrating, non-comedogenic moisturizer that won’t clog your pores.
- Apply Sunscreen (Morning Routine): If you’re using salicylic acid in the morning, always follow up with sunscreen. Salicylic acid can make your skin more sensitive to the sun, so SPF is essential.
If you are treating acne, you should apply salicylic acid in the morning and retinol in the evening till the blemish starts to fade. But remember, less is more, always use a pea-sized amount for your face to avoid irritation and don’t scrub your face with it. Let the products do its thing. Most over-the-counter salicylic acids are found in 0.5-2% concentrations
If you observe any irritation, try to use a much lower concentration
Percentage Of Salicylic Acid For Beginners
Most over-the-counter salicylic acid range from 0.5% to 2%. If you want to get the maximum effect, I generally like going for the 2%. As a beginner, start slowly and build your way up. Salicylic acid comes in many forms such as cleansers, fash wash, toners, and moisturizers. It takes up to 6-8 weeks before seeing any improvement at all, Don’t believe the unrealistic changes and take your time!
How Often Should You Use Salicylic Acid Serum?
Start by using salicylic acid serum 2-3 times a week to see how your skin reacts. If your skin tolerates it well, you can gradually increase the frequency. However, be cautious not to overuse it, as too much salicylic acid can lead to dryness, irritation, and increased sensitivity.
Side Effects Of Salicylic Acid
Combination with other actives
If you are already using enough actives and want to introduce salicylic acid into the mix, you need to proceed with caution and salicylic acid can cause more tingle and sensitivity when used with other actives.
Allergy
if you are allergic to aspirin or salicylate. You should never apply salicylic acid if you are allergic to wintergreen, peppermint, spearmint and willow bark extract. Also, if you are allergic to aspirin, avoid salicylic acid.
Check your formulation
Also, choose your formula carefully. Some products may contain denatured alcohol as part of the formula to help solubilize the salicylic acid and that can make it extra drying. Sometimes dryness may not necessarily come from salicylic acid but from other ingredients present in the formula. So always look out for formulas that are more hydrating and absence of alcohol.
Not allergic and usage in pregnancy
If you are not allergic to any salicylic acid ingredients then the side effects might be mild dryness and the irritation profile is pretty low. Salicylic acid is known to be well tolerated. However, if you are a breastfeeding mum or pregnant or allergic to aspirin, salicylic acid is not for you.
Is Salicylic Acid Worth The Hype?
Definitely a YES! It is an excellent exfoliant particularly good for those with oily to combination skin types. It is an excellent ingredient for those with acne-prone skin. I recommend a leave-on preparation with 1 to 2% salicylic acid. Also, look for those with alcohol-free preparation.

Tips for Using Salicylic Acid Serum
- Don’t Overdo It: Less is more when it comes to salicylic acid. Overuse can irritate your skin and disrupt its natural barrier.
- Combine Wisely: Be cautious when combining salicylic acid with other active ingredients like retinol, benzoyl peroxide, or vitamin C, as this can increase the risk of irritation.
- Hydrate: Salicylic acid can be drying, so make sure you’re keeping your skin well-hydrated with a good moisturizer.
- Listen to Your Skin: If you notice excessive dryness, peeling, or irritation, reduce the frequency of use or switch to a lower concentration of salicylic acid.
Who Should Avoid Salicylic Acid?
While salicylic acid is beneficial for many, it’s not suitable for everyone. If you have very dry, sensitive, or rosacea-prone skin, or are allergic to aspirin, salicylic acid may exacerbate these conditions. Pregnant or breastfeeding women should consult a doctor before using salicylic acid, as high concentrations may not be recommended.
