The ISOV G-Tightening Liquid is a professional chemical peel formulated with 40% Glycolic Acid at pH 2.5, designed to deliver rapid epidermal penetration and stimulate advanced skin renewal processes. Due to its low molecular weight, glycolic acid penetrates efficiently through the stratum corneum, breaking down desmosomal bonds and promoting accelerated exfoliation.

This mechanism enables not only surface resurfacing but also deeper stimulation of fibroblast activity, supporting collagen synthesis and contributing to visible skin tightening and improved structural integrity. The result is enhanced firmness, refined texture, and reduction in fine lines and uneven skin tone.

Due to its fast penetration profile, precise control during application is critical. The peel must be neutralised using the ISOV GL-Skin Balance Activator to immediately stop acid activity, ensuring safe treatment depth and preventing over-exfoliation or irritation.

Positioned as a more intensive resurfacing option within the ISOV system, the G-Tightening Liquid is ideal for thicker, resilient skin types and advanced anti-ageing protocols where increased stimulation and tightening effects are required.
