The Isntree Exfoliating Tonic Chestnut BHA 0.9% Clear is a specialized facial toner designed for effective yet gentle exfoliation. This 200 ml formulation contains 0.9% betaine salicylate, a BHA derivative that penetrates pores and removes dead skin cells without causing excessive irritation. The chestnut extract provides additional antioxidant benefits and soothes the skin during the exfoliation process. This clear, lightweight liquid toner is suitable for various skin types, particularly for those with congestion, uneven texture, or excessive oil production. The alcohol-free formulation maintains the skin's natural pH and offers consistent exfoliation benefits. To use, apply a small amount to a cotton pad and gently swipe over cleansed skin, typically once daily or according to individual skin tolerance. The product comes in a convenient 200 ml bottle with a secure closure to prevent leaks and maintain product integrity. Regular use can improve skin clarity, refine the appearance of pores, and promote a smoother skin texture through gradual, controlled exfoliation. The formulation avoids common irritants and focuses on the exfoliating benefits of BHA in a well-tolerated concentration. This toner represents a balanced approach to chemical exfoliation, combining effective ingredients with consideration for skin comfort and long-term usability.
