When hair follicles (pores) get plugged with dead skin cells and oil, blackheads (open plugged pores), whiteheads (closed plugged pores), or pimples (pustules) often appear.
Salicylic acid penetrates the skin and dissolves dead skin cells that clog the pores. Its effectiveness varies from person to person, depending on the acne condition.
How Does Salicylic Acid Work?
Salicylic acid is a beta hydroxy acid (BHA) known for its ability to penetrate deep into the pores. Making it a powerful ingredient for skin exfoliation. But how exactly does it work? Let’s explore its benefits and how to use it correctly:
- Exfoliating the Skin: Salicylic acid helps remove dead skin cells, preventing them from clogging pores.
- Unclogging Pores: It dissolves excess sebum and debris, reducing the formation of blackheads and whiteheads.
- Fighting Bacteria: Though not an antibacterial agent, it helps create an environment less favourable for acne-causing bacteria.
- Reducing Inflammation: It has anti-inflammatory properties that calm redness and swelling associated with acne.
How to Use Salicylic Acid for Acne
To maximize the benefits of salicylic acid, follow these steps:
- Choose the Right Product: It is available in cleansers, toners, serums, and spot treatment products.
- Start with a Low Concentration: Most products contain 0.5% to 2% salicylic acid. You should always start with a lower concentration if you have sensitive skin.
- Use once or Twice Daily: Apply it as directed, but always avoid overapplication and overuse, which may lead to dryness and irritation.
- Follow with Moisturizer: Since salicylic acid can dry out the skin, use a hydrating moisturizer to maintain balance.
- Apply Sunscreen: Salicylic acid can make your skin more sensitive to the sun, so always use SPF during the day.
Potential Side Effects
Though generally safe, salicylic acid can cause:
- Irritation and redness
- Dryness and peeling
- Increased sun sensitivity
If severe irritation occurs, reduce usage or consult a dermatologist.
What form and dosage of salicylic acid is recommended for acne?
Dosage is generally based on skin type and condition. A doctor might recommend that you apply a limited amount to a small area of affected skin for 2 or 3 days to test your reaction before applying it to the entire area.
According to the National Library of Medicine, adults should use a topical product to clear their acne, such as:
Form Percent of salicylic acid How often to use
Gel 2–7% Once per day
Lotion 2% 1–3 times per day
Ointment 3% As required
Pads 0.5–2% 1–3 times per day
Soap 0.5–3% As required
Solution 0.5–2% 1–3 Times a day
Conclusion
Salicylic acid is an effective acne treatment, particularly for clogged pores and oily skin. When used correctly, it helps prevent breakouts and improves skin texture. However, following proper skincare routines and using it in moderation is essential to avoid irritation. If acne persists, seeking professional advice is recommended.
