This multi-tasking booster serum is designed to support skin’s overall condition by combining 6 functional peptides with skin-revitalising ingredients. Formulated to target firmness, texture, pores, and tone, it serves as a powerful first step in your routine to maximise the absorption and efficacy of follow-up products.

The 6-peptide complex works to promote collagen production, minimise the look of pores, and refine skin texture, while niacinamide helps brighten dull areas and even tone. Hyaluronic acid and allantoin provide hydration and soothing care, making this formula ideal even for sensitive or irritation-prone skin.
