Isntree Chestnut BHA 2% Clear Liquid (100ml)

The Isntree Chestnut BHA 2% Clear Liquid is a Korean chemical exfoliating toner that combines 2% Salicylic Acid (BHA) with Castanea Crenata Shell Extract to provide an all-in-one pore cleansing and pore-tightening treatment in a single step. Stabilised at pH 4 ± 1, the formula is optimised for maximum BHA efficacy while remaining gentle enough for first-time exfoliant users.

The addition of Chestnut Shell Extract — rich in natural Tannins — takes this beyond a standard BHA toner by simultaneously tightening the pore opening after the BHA has cleared it from the inside. Three forms of Hyaluronic Acid ensure the exfoliation process does not compromise moisture levels, keeping skin balanced and comfortable after every use.

Key Benefits of Isntree Chestnut BHA 2% Clear Liquid

• 2% Salicylic Acid penetrates oil-filled pores to dissolve excess sebum, dead skin cells, and surface congestion without physical scrubbing
• Upcycled Chestnut Shell Extract delivers natural Tannins that visibly tighten the appearance of enlarged pores and restore the skin's oil-water balance
• Triple Hyaluronic Acid complex — Hyaluronic Acid, Sodium Hyaluronate, and Hydrolyzed Hyaluronic Acid — seals in moisture at multiple skin depths to prevent post-exfoliation dryness
• Willow Bark Extract (Salix Alba) provides additional mild exfoliating support alongside BHA, contributing to smoother skin texture with consistent use
• Allantoin soothes and calms the skin surface during and after exfoliation, reducing redness and discomfort associated with active ingredient use
• Stabilised at pH 4 ± 1 to ensure maximum BHA activity — mild enough for beginners yet effective enough for experienced exfoliant users

Skin Types and Concerns

• Oily and combination skin: 2% Salicylic Acid breaks down sebum inside the pore and visibly reduces surface shine, while Tannins help keep oil-water balance in check throughout the day
• Acne-prone skin: BHA's oil-soluble nature allows it to clear the type of pore blockages that lead to blackheads and closed comedones, reducing their formation with regular use
• Sensitive skin: Mild pH formulation, Allantoin, and Dipotassium Glycyrrhizate (Licorice Root) keep the exfoliation experience calm and non-irritating, suitable for those who have previously reacted to stronger exfoliants
• Rough and uneven skin texture: Salicylic Acid and Willow Bark Extract together accelerate cell turnover, progressively smoothing the surface and improving tone with consistent 2 to 3 times per week use
