INGREDIENT EDUCATION
Salicylic Acid: Benefits, Uses, How to Use & Side Effects
Learn what salicylic acid does for skin, why it is commonly used for acne and clogged pores, how to introduce it into your routine, and what to know about dryness and irritation.
INGREDIENT BASICS
What Is Salicylic Acid?
Salicylic acid is a beta hydroxy acid, commonly abbreviated as BHA. It is widely used in skincare products formulated for blemish-prone, oily and congested skin.
Unlike some exfoliating ingredients that primarily work on the skin's surface, salicylic acid is oil-soluble. This property is one reason it is commonly included in products intended to address excess oil and clogged pores.
Salicylic acid is an exfoliating active.
Because it is an active skincare ingredient, using more does not necessarily mean better results. Frequency and product strength should be appropriate for your skin and the product directions.
KEY BENEFITS
What Does Salicylic Acid Do for Skin?
Salicylic acid is especially well known for its use in routines focused on clogged pores, blackheads and acne-prone skin.
Helps Exfoliate
Salicylic acid helps remove dead skin cells and is commonly used as a chemical exfoliating ingredient.
Helps With Clogged Pores
Its oil-soluble nature makes it particularly useful in formulations targeting pore congestion.
Useful for Oily Skin
Salicylic acid is frequently included in skincare designed for skin that produces excess oil.
Supports Acne-Focused Routines
It is commonly used in acne-focused skincare because of its exfoliating and pore-clearing properties.
ACNE & BREAKOUTS
Is Salicylic Acid Good for Acne?
Salicylic acid is a common ingredient in products intended for acne-prone skin. It can help exfoliate and address the buildup associated with clogged pores.
Acne can have multiple contributing factors, however, so one ingredient will not necessarily address every type of breakout. Persistent or severe acne may require professional medical evaluation.
01
Start With the Product Directions
Follow the recommended frequency and application instructions rather than automatically using the product every day.
02
Monitor Your Skin
Watch for excessive dryness, burning, persistent redness or irritation after introducing an exfoliating product.
03
Keep the Rest of the Routine Simple
Avoid adding multiple new active ingredients at the same time, particularly if your skin is sensitive.
CLOGGED PORES
Salicylic Acid for Blackheads & Clogged Pores
Blackheads are open comedones that develop when material accumulates inside a pore. Salicylic acid is commonly used in skincare aimed at this type of congestion.
Blackheads
Salicylic acid can help exfoliate within the pore environment and is commonly found in products targeting blackheads.
Whiteheads
It is also commonly used in routines designed to address closed comedones and other forms of pore congestion.
Enlarged-Looking Pores
Pores can appear more noticeable when congested. Managing excess oil and buildup may improve their appearance.
Oily T-Zone
Salicylic acid is frequently used in products targeting oily areas such as the forehead, nose and chin.
HOW TO USE
How to Use Salicylic Acid in Your Routine
The correct method depends on whether you are using a cleanser, serum, toner, spot product or another formulation. Always follow the instructions on the specific product.
01
Cleanse
Start with a gentle cleanser unless your salicylic acid product is itself a rinse-off cleanser.
02
Apply Salicylic Acid
Apply the product according to its directions. Do not automatically increase the amount or frequency.
03
Moisturise
Use a suitable moisturiser to help keep your routine comfortable, particularly if exfoliation leaves your skin feeling dry.
04
Use Sunscreen During the Day
Broad-spectrum sunscreen is an important part of a daytime skincare routine.
SKIN TYPE GUIDE
Who Can Use Salicylic Acid?

Acne-Prone Skin
Commonly used as part of skincare routines focused on blemishes and comedonal acne.

WHAT TO WATCH FOR
Salicylic Acid Side Effects & Common Mistakes
Exfoliating products can cause irritation when used too often or when combined with too many other strong active ingredients.
- Excessive dryness or tightness.
- Burning or stinging.
- Persistent redness or irritation.
- Using several exfoliating products at the same time.
- Increasing frequency too quickly.
- Scrubbing the skin aggressively while also using chemical exfoliants.
More active does not always mean better.
If your skin becomes persistently irritated, simplify your routine and consider speaking with a qualified healthcare professional if symptoms are severe or do not improve.
