£12.00 / 30ml
What you get: A lightweight, non-drying beta hydroxy acid (BHA) exfoliating serum with 2% Salicylic Acid that penetrates deep into pores to unclog blackheads and reduce blemishes, plus 1% Hyaluronic Acid to maintain skin hydration and prevent dryness.


Why it works: 2% Salicylic Acid (BHA) gently but effectively dissolves the buildup that causes blackheads and blemishes by exfoliating inside pores. 1% Hyaluronic Acid helps maintain skin's moisture barrier, preventing the dryness often associated with exfoliating acids.


How it feels: Ultra-lightweight, fast-absorbing serum texture that layers beautifully under other skincare. A targeted treatment for congested, blemish-prone skin that leaves skin feeling balanced and refined without tightness or irritation.


When to use: Apply to cleansed skin morning and/or evening. Use 1-2 drops, gently patting into face and neck. Follow with your preferred serums and moisturiser. Always apply SPF as the final step in your AM routine when using exfoliating acids.

Suitable for:

  • Normal skin
  • Oily skin
  • Combination skin
  • Pregnancy & breastfeeding

Targets:

  • Blemishes & congestion
  • Excess oil
  • Blackheads

Understanding Beta Hydroxy Acids

What makes BHA special? Unlike AHAs that work on the skin's surface, Beta Hydroxy Acid (Salicylic Acid) is oil-soluble, allowing it to penetrate into pores and work from within. 2% Salicylic Acid is the optimal concentration for effective exfoliation without irritation. Higher concentrations are typically reserved for professional treatments.

Why We Added Hyaluronic Acid 1% low-molecular-weight Hyaluronic Acid prevents the dryness often associated with exfoliating acids, making this suitable for daily use.

Perfect Partners:

  • Salicylic Acid Cleanser (double the pore-clearing power)

  • Omega Water Cream (oil-free moisture for blemish-prone skin)

  • Niacinamide Serum (reduces oil production and calms irritation)

Reviews Summary
Customers say this serum effectively reduces blackheads and minimizes pore appearance, particularly around the nose area. The watery texture absorbs quickly without feeling sticky or heavy, though some note initial stickiness before drying. Many appreciate that it doesn't dry out their skin while providing gentle exfoliation. Users report clearer, smoother skin texture and reduced breakouts with consistent use. Several mention it works well in combination with other skincare products. Common feedback includes the small bottle size running out quickly. While most see positive results within weeks, some experience initial purging or breakouts. A few users report no noticeable improvements or skin irritation.

    Ok so far

    I’ve not been using this long so can’t really comment on results. It is easy to use and hasn’t caused a reaction with my sensitive skin. I’ll continue to use as part of my evening skin care routine.

    Excellent

    I have sensitive skin which became a bit congested over the summer. I was wary trying this but I have to say I had no reaction or sensitivity and my skin is becoming so much better.

    Not for me.

    I bought this for blackheads and ended up with pimples!

    Hi Tann, thank you for your honest feedback - we're sorry this wasn't the result you were hoping for.
    This may actually be purging. BHA works deep inside the pore to clear congestion, which can bring blockages that were already forming to the surface faster than usual - so they appear as spots before they clear. It typically settles within 4–6 weeks, and skin is usually clearer on the other side of it.
    That said, every skin is different - if this feels more like irritation than purging, please stop using it and reach out to our Customer Experience Team on help@theinkeylist.com. They'd love to help you figure out what's going on and find the best route to tackling blackheads. 💙
