Skin prone to blackheads, clogged-looking pores and uneven texture looking for a 2% salicylic acid leave-on exfoliant
Consider it if you want a fragrance-free BHA exfoliant for pores, blackheads and skin texture, and your skin already tolerates exfoliating acids.
Score by pillar
Claims: what the evidence supports
| Brand promise | Verdict | Evidence |
|---|---|---|
| Helps visibly unclog pores and improve the look of blackheads | Supported, within a narrow frame | Opened 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 BHA | Supported, within a narrow frame | The 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 humectants | Supported, within a narrow frame | INCI 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 skin | Partially supported | The 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 flares | Out of scope | The 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.
