Salicylic Acid 0.66% Serum

Clear, Smooth, Brighter Skin

This gentle serum is formulated with 0.66% Salicylic Acid (BHA) to help unclog pores, reduce blemishes, and reveal smoother, more even-looking skin. Its lightweight, fast-absorbing texture makes it easy to add to your routine without irritation.

Key Benefits:

  • Helps prevent and reduce blemishes and breakouts
  • Gently exfoliates inside pores to improve texture
  • Supports the appearance of post-acne marks and uneven skin tone
  • Promotes a subtle brightening effect for healthier-looking skin

Why You’ll Love It:

Salicylic Acid is perfect for acne-prone skin. It keeps pores clear, reduces the appearance of blemishes, and supports smoother, brighter skin over time. At 0.66%, it’s gentle enough for regular use, making it a simple yet effective step after cleansing.

Ideal For:

  • Oily or combination skin
  • Skin prone to blackheads, whiteheads, or breakouts
  • Uneven texture or post-acne marks
  • Anyone looking for a gentle exfoliating serum that also supports a brighter complexion

How to Use:

  • Apply a few drops to clean, dry skin.
  • Use 2–3 times per week, either in the morning or at night, before your moisturizer or night cream.
  • If used in the morning, follow with SPF.

Tip: Start slowly to let your skin adjust, then increase frequency as tolerated.

May Help with;

  • Acne / Breakouts:  Salicylic acid is a BHA that penetrates pores to remove excess oil and debris, helping prevent and reduce breakouts.
  • Scars / Marks:  It doesn’t directly fade scars, but by keeping skin clear and exfoliating gently, it can reduce post-acne marks over time and improve skin texture.
  • Brightening / Uneven Tone:  Its mild exfoliating action can help reveal fresher, smoother skin, giving a subtle brightening effect, especially when combined with ingredients like niacinamide or vitamin C.

 

What Is Salicylic Acid Good For?

Helps Defend Against Acne-Causing Bacteria

 

 

Salicylic acid is a popular skincare ingredient known for its effectiveness in managing acne. It works by clearing out blocked pores—removing dead skin cells and excess oil—which creates a less inviting environment for acne-causing bacteria to thrive. While it won’t completely eliminate bacteria on its own, it can significantly reduce breakouts and support clearer skin overall.

 

If you’re prone to blackheads or blemishes, salicylic acid is a go-to ingredient to help keep things under control.

 

Note: It’s not uncommon to see a temporary increase in breakouts when you first introduce salicylic acid into your routine. This is part of a natural process called “purging” (explained below) and usually resolves within a few weeks.

 


 

 

Can You Use Salicylic Acid Every Day?

 

 

Yes, you can use salicylic acid daily, but it’s best to start slowly—especially if your skin is sensitive or new to exfoliating acids.

 

Begin with 1–2 applications per week and gradually build up to daily use if your skin tolerates it well. Regular use helps to prevent clogged pores, reduce oiliness, and maintain a smoother, more refined skin texture.

 


 

 

Does Salicylic Acid Cause Skin Purging?

 

 

Salicylic acid increases the rate of skin cell turnover. As a result, it may cause purging, which is when underlying build-ups like oil, dead skin, and debris surface all at once—leading to a temporary breakout.

 

Unlike irritation or allergic reactions (which often trigger breakouts in new or unusual areas), purging tends to happen in the same spots where you normally experience pimples. The difference is: purging breakouts generally clear up faster and signal that the product is actively working.

 

If you’re concerned about whether you’re experiencing purging or irritation, observe the location, type, and duration of your breakouts. If symptoms persist beyond 6 weeks or worsen, discontinue use and consult a skincare professional.

 


 

 

Can You Use Salicylic Acid with Niacinamide?

 

 

Yes—salicylic acid and niacinamide are a powerful pair! These two ingredients complement each other and are especially effective for oily or acne-prone skin.

 

  • Salicylic acid: penetrates deep into pores to unclog them and reduce oil buildup.

  • Niacinamide: hydrates the skin, soothes inflammation, and supports the skin barrier.

 

 

When used together, they help improve skin clarity while maintaining balance—leaving your complexion refreshed, calm, and moisturised.

 


 

 

Does Salicylic Acid Make Acne Worse Before It Gets Better?

 

 

It can—temporarily. The initial stage of purging may make it seem like your acne is getting worse, but this is just your skin adjusting and detoxifying.

 

This phase shouldn’t last more than 4–6 weeks. After that, you should begin to notice clearer, brighter, and smoother skin. If irritation continues or worsens beyond that point, it’s best to stop using the product and seek professional advice.
