Overview

A lightweight Korean peptide serum designed as a first-step booster for everyday routines. The generous 150ml format suits anyone wanting softer texture, steadier tone and a calmer-looking complexion without a sticky finish. It works well for mixed or combination skin that needs several concerns addressed in one simple layer.

Key benefits

  • Supports a firmer, smoother appearance over time
  • Softens the look of fine lines and uneven texture
  • Encourages a more even-looking skin tone
  • Feels non-sticky and absorbs quickly under other products
  • Useful as a light booster before serums or moisturiser
