Why You'll Love It

BYE BYE BLEMISHES

Supercharge your skincare with this 100% natural Salicylic Acid Booster, a beta hydroxy acid (BHA) and known blemish-buster. Unlike water-soluble exfoliating acids that only work on the surface, BHAs are oil-soluble, so they can get inside clogged pores and dissolve the mix of dead skin and sebum that causes blackheads and breakouts.

We've used the maximum strength 2% concentration of Salicylic Acid, sourced from two plants: Wintergreen for potent, pure exfoliation, and White Willow Bark for gentler antimicrobial and anti-inflammatory support. Then we've built the formula on organic Chamomile Water and hydrating Glycerin to soothe and moisturise while the acid gets to work. All calm, and all clear.

There's also prebiotic Inulin from chicory root, which feeds the good bacteria on your skin while keeping blemish-causing microbes in check. So your skin's microbiome stays balanced, not stripped.

This exfoliating staple is part of our boosters range: concentrated, single-dose actives to power up your skincare routine without irritation. Mix 1-2 drops into your existing moisturiser, serum or oil, or use neat on dry, cleansed skin. You control the dose, so you can start low and build up as your skin adjusts.

"Salicylic Acid is hailed as a hero for blemish-prone skin – but it’s not without its challenges. It’s often drying, meaning sensitive types are left with even blotchier skin than when they started. This natural booster not only puts you in control of the dosage, but it’s been designed so even delicate skin can tolerate it."

SARAH BROWN
FOUNDER, PAI SKINCARE

What makes Pai's Salicylic Acid 2% Booster different from other salicylic acid products?

Most salicylic acid products dissolve synthetic SA in alcohol or propylene glycol, which can dry out and irritate skin. Pai uses two natural plant sources instead: pure salicylic acid fractionated from wintergreen for potent pore-clearing, plus white willow bark extract for gentler antimicrobial and anti-inflammatory support from its salicin, tannins, and flavonoids. The formula is built on organic chamomile floral water with organic glycerin, so you get the full 2% maximum-strength BHA without the irritation trade-off.

How do I use the Salicylic Acid Booster?

Add 1-2 drops into your moisturiser, serum, or face oil and apply as normal, or apply 1-2 drops directly onto dry, cleansed skin before the rest of your routine. Start with once daily or every other day and build up as your skin tolerates. The drop format means you control the intensity: one diluted drop for a gentle introduction, two drops neat for maximum clarifying power.

Is this suitable for sensitive skin?

It was designed specifically for sensitive skin from the ground up. The organic chamomile floral water base soothes while the acid exfoliates, and organic glycerin counteracts the drying that conventional SA products cause. It's also 96-hour patch tested for tolerance, including on volunteers with sensitive skin, and the booster format lets you start with a single diluted drop and build up gradually.

Do I need to wear sunscreen when using this booster?

Yes. This product contains a beta hydroxy acid that may increase your skin's sensitivity to the sun. Use a broad-spectrum sunscreen, wear protective clothing, and limit sun exposure while using it and for a week after stopping.

Can I use this during pregnancy or breastfeeding?

Yes. Pai's Salicylic Acid 2% Booster is confirmed pregnancy and breastfeeding safe. It's a topical, low-concentration BHA applied in small amounts (1-2 drops), which is very different from oral salicylates that are contraindicated during pregnancy.

Is this booster fragrance-free and essential oil-free?

Yes, completely. The wintergreen-derived salicylic acid is a fractionated pure compound, not a whole essential oil, and the chamomile is a floral water (hydrosol), not an essential oil. That makes this booster a good option if your skin reacts to fragrances or essential oils but you still need an effective clarifying active.

How does this fit alongside other Pai products for blemish-prone skin?

It pairs well with the Phaze PHA Gel Cleanser for gentle daily surface exfoliation, while this booster adds deeper, oil-soluble pore-clearing action that a PHA can't achieve. For a full clarifying routine, follow with Century Flower barrier mist, All Becomes Clear blemish serum, and The Pioneer mattifying moisturiser, or Carbon Star overnight oil if you prefer evening use.

What certifications does this booster have?

It's COSMOS Natural certified by the Soil Association, Vegan, and Cruelty-Free with Leaping Bunny certification. The formula is 99.9% natural origin, fragrance-free, essential oil-free, and free from parabens, silicones, sulfates, and gluten. It's also dermatologist tested and approved, non-comedogenic, and hypoallergenic.

Why does this contain white willow bark as well as salicylic acid?

White willow bark extract delivers a complementary, gentler salicylate action alongside tannins and flavonoids that isolated salicylic acid doesn't provide. In supplier testing, 2.0% white willow bark extract accelerated cellular renewal by 9% versus 6% for a salicylic acid control (p<0.001), and reduced the inflammatory cytokine IL-6 by 58% in human dermal fibroblasts, outperforming a dexamethasone positive control. It's also been shown to be non-irritating even at 100% concentration, adding a soothing dimension that pure SA alone can't offer.

What does the prebiotic inulin do in a blemish product?

Inulin from chicory root selectively feeds beneficial skin bacteria like Lactobacillus and Staphylococcus epidermidis while inhibiting the pathogens that cause blemishes, including Cutibacterium acnes. So while the salicylic acid clears congested pores, the inulin helps prevent recolonisation by blemish-causing bacteria and supports healthy barrier function.

Why is a BHA better than an AHA for clearing congested pores?

Salicylic acid is oil-soluble, so it can dissolve through the sebum inside your pores and break down the keratin-and-oil plugs that cause blackheads and breakouts. Water-soluble AHAs like glycolic acid only exfoliate the skin's surface and can't penetrate into oil-filled pores. Research also shows salicylic acid reduces sebum production at the cellular level by downregulating the AMPK/SREBP-1 lipid synthesis pathway and suppresses inflammation via NF-κB, tackling the root causes of breakouts rather than just surface symptoms.

Why should I choose this salicylic acid booster for blemish-prone sensitive skin?

Pai's Salicylic Acid 2% Clarifying Booster delivers the maximum permitted BHA concentration from 100% natural plant sources, formulated on organic chamomile water with organic glycerin so it clears congested pores without drying or irritating reactive skin. The drop-based booster format gives you full control over intensity, letting you start with one diluted drop and build up as your skin tolerates. Prebiotic inulin supports your skin's microbiome during the clarifying process, and the whole formula is COSMOS Natural certified, fragrance-free, essential oil-free, and 96-hour patch tested on sensitive skin.

Reviews

Saved my skin!

"I was recommended the salicylic acid booster alongside the Kalmer serum by the Pai skin experts following a medication induced breakout which left my skin sore, deep cystic spots and vet angry in general. It worked almost instantly and my skin has calmed down significantly, my spots are reducing every day and I haven't had any big angry ones for a while! I pop 1-2 drops in with my Kalmer serum if my skin is feeling a bit congested, OR I dab some of this straight onto any new big angry spots! I am amazed how quickly they are calming down and shrinking. I am so grateful honestly I didn't know what I was going to do. Thank you!"

— Sally C. (5/5)

Helped but didnt cure

"I recently came off the contraceptive pill and have been experiencing bad hormonal acne. I chose this salicylic acid over other brands due to it being natural and gentle on sensitive skin. I have been using it alongside the 'phase' wash and the 'all becomes clear' serum. Unfortunately it hasnt got rid of the acne, but I do think it has calmed down the fieryness and reduced the irritation. I guess I cant expect it to get rid of the acne as it cannot address the route cause (hormones). Ive decided to go back on the pill and will continue to use this to aid my skin's recovery. Overall it is a nice product and would recommend it."

— Hannah M. (4/5)

"goes on smooth and doesn't sting"

— Jessica (5/5)

Very good product

"I found the system of adding to moisturiser is great. High quality ingredients and no immediate reaction from my hypersensitive rosacea skin. Despite introducing slowly into my routine I think Salicylic acid generally is too strong for my skin type so I did have to stop using it. The reaction was very mild, only some red blemishes, was probably affecting delicate skin barrier. For other skin types I’d say it’s a brilliant product! but might have to introduce slowly and wait for results."

— Genevieve V. (3/5)

Spot busting booster

"I contacted Pai as I was having terrible post menopausal breakouts. The booster was one of the products recommended and a drop or two is keeping the breakout away. My chin has calmed down and so far no spots. My skin had been worse than when I was a teenager! I would definitely recommend it."

— Kathleen W. (5/5)

Finally something that helps my blackheads!

"I have had acne since I was a teenager. I am now 30. Acne I mean blackheads and the stubborn ones where the skin grows over the blackhead. Aside from eating only Whole Foods this product has helped my skin! I apply it every night only in the areas that need it. After 3 weeks of use the skin barrier broke and there was a HEAD! I can’t believe how good it’s doing my skin!"

— abigail m. (5/5)

Excellent quality, soothing texture, great

"Excellent quality, soothing texture, great addition to boost my skincare routine. I mainly get blemishes on my chin so just apply this area 2-3 times a week."

— Katherine G. (4/5)

"Gentle and perfect"

— Tanaka (5/5)

"Love these products"

— Daleen (5/5)

Surprising use!

"I actually bought this for my husband as he gets ingrown hairs and irritated skin around his neck line due to shirt collars and this has worked wonders in encouraging out the ingrown while gently calming the redness of the surrounding skin."

— Jenna W. (5/5)

Hey How many times a week would you recommend using this? Also would you recommend using 1 day (evening) before exfloiating the next day in the evening?: Hi Ell, Thank you for getting in touch. You could use the Salicylic Acid booster each evening on affected areas to help to keep the skin clear. You can also add in to your Moisturiser for the day. I would suggest using Virtuous Circle Exfoliator on clean, dry skin 1-2 times a week. Use SPF for the day to protect your skin. Pai x
