Multi-target skincare in one step.
This powerful booster serum combines six types of peptides with hydrating and barrier-supporting ingredients to improve overall skin condition — including pores, texture, tone, firmness and sebum. Designed to be used as the first step after cleansing, it prepares your skin for the rest of your routine while delivering visible improvements in smoothness, clarity and radiance.

Key Benefits

• Enhances skin firmness and improves the appearance of fine lines

• Reduces visible pores, refines skin texture and supports clearer skin

• Improves skin tone, brightness and overall radiance

• Balances sebum, calms redness and supports barrier health

• Lightweight, non-sticky texture that layers well with other products

Key Ingredients

• 6 Peptide Complex — including SH-Polypeptide-121 (collagen-boosting), Copper Tripeptide-1 (retexturizing), Dipeptide Diaminobutyroyl Benzylamide Diacetate (sebum & pore care), Oligopeptide-68 (brightening), Palmitoyl Tripeptide-8 (soothing), and Acetyl Hexapeptide-8 (firming)

• Niacinamide — brightens skin tone, refines texture and supports barrier function

• Sodium Hyaluronate & Hydrators — deeply hydrate and plump skin

• Allantoin & Soothing Agents — calm sensitivity and promote skin recovery

How to Use

1. After cleansing, apply 2–3 pumps (or appropriate amount) of the serum onto clean skin.

2. Use it as the first step in your skincare routine (before other serums/creams).

3. Gently pat until absorbed, then follow with your usual treatments and moisturizer.

4. Use daily, morning and/or evening for best results.

Tips & Cautions

• Suitable for most skin types, but always patch-test new products.

• Because this acts as a booster step, ensure you follow with a moisturizer to lock in the benefits.

• Avoid using it with too many strong actives at once if your skin is sensitive.

• Store in a cool, dry place away from direct sunlight and high heat.
