Metrin Revitalizing Glycolic Complex

A targeted AHA glycolic acid serum that helps lift dull, dead skin cells and support a smoother, clearer surface. This formula accelerates the skin’s natural renewal cycle to improve tone, texture, and visible clarity — all while staying gentle enough for regular night-time use.

Benefits

• Supports a brighter, more even complexion
• Refines texture and helps minimise the look of pores
• Reduces dullness caused by slow cell turnover
• Helps soften the appearance of fine lines and early wrinkles
• Clears away buildup to improve overall skin clarity
• Helps other Metrin steps work more effectively
• Aloe, allantoin, and panthenol help calm and comfort the skin

How It Works

Glycolic acid is a small-molecule AHA that loosens the bonds between dead surface cells. This helps the skin shed old, dull layers and encourages fresh cells to surface more smoothly. Younger skin turnover lowers the risk of irritation, and the formula includes aloe, allantoin, and panthenol to support comfort during use.

Regular use promotes clearer pores, a more even tone, and better long-term skin renewal — an important part of skin longevity.

• Uneven texture
