Consider it if you want a fragrance-free BHA exfoliant for pores, blackheads and skin texture, and your skin already tolerates exfoliating acids.

Claims: what the evidence supports

Brand promiseVerdictEvidence
Helps visibly unclog pores and improve the look of blackheadsSupported, within a narrow frameOpened official pages identify a 2% salicylic acid/BHA leave-on exfoliant; PubMed sources on blemish-prone skin support salicylic acid’s keratolytic and comedolytic role, without proving an identical result for every user.
Gradually smooths the look of skin texture with an acidic BHASupported, within a narrow frameThe opened UK page declares salicylic acid 2%, and INCI Decoder cross-checks the formula with salicylic acid, solvents/humectants and green tea; the inference remains ingredient/close-formula evidence.
Fragrance-free, denatured-alcohol-free formula centred on salicylic acid, green tea and humectantsSupported, within a narrow frameINCI Decoder lists Water, Methylpropanediol, Butylene Glycol, Salicylic Acid, Polysorbate 20, Camellia Oleifera Leaf Extract, Sodium Hydroxide and Tetrasodium EDTA, with alcohol-free and fragrance/essential-oil-free signals.
Suitable for daily use on all skinPartially supportedThe product is marketed as a regular exfoliant, but BHA tolerance varies substantially; gradual introduction and frequency adjustment are more cautious than a universal daily-use promise.
Replaces qualified assessment for inflammatory lesions, scars or persistent flaresOut of scopeThe PubMed sources relate to broader dermatology contexts; CosmeticFountain does not publish a lesion-correction claim for this cosmetic.

What the evidence does not show. The evidence does not allow the promise to be extended beyond the measured criteria.

Formulation

An INCI reading and the coherence of the formula with the headline promise. Ingredients can support the plausibility of a formula; they are no substitute for evidence on the finished product.

INCI — key actives and filters

  • Salicylic Acid 2%
  • Methylpropanediol
  • Butylene Glycol
  • Camellia Oleifera Leaf Extract
  • Sodium Hydroxide

Safety and precautions

This dossier supports cautious cosmetic exfoliation and pore-appearance benefits. It does not make the product an answer for inflammatory lesions, scars or skin disease; persistent irritation or a significant reaction calls for stopping and getting appropriate advice.

Pregnancy or breastfeeding: seek professional or pharmacy advice before use, particularly with a device or a potentially irritating active.

Take care if: damaged skin, persistent irritation, photosensitivity, ongoing dermatological care.

Usage advice

Follow the product label. Pair when relevant with simple barrier care and suitable sun protection.
