About the Product

Peptides are small proteins that help support your skin's structure and firmness over time. This lightweight, watery serum blends six different peptides to target multiple concerns at once — think fine lines, texture, pores, and overall tone. It absorbs fast and works as a boosting step right after cleansing to help everything you layer on top work better.

Who is This For?

Suitable for all skin types — especially helpful if you're noticing early fine lines, uneven texture, or enlarged pores, but works well for anyone wanting a multi-tasking first step in their routine.

Key Benefits

  • Supports skin firmness and elasticity with six targeted peptides
  • Helps soften the look of fine lines and expression lines
  • Works to minimize pore appearance and balance oil production
  • Evens out skin tone and texture for a smoother finish

Key Ingredients

  • Copper Tripeptide-1 — Supports skin renewal and helps improve firmness
  • Acetyl Hexapeptide-8 — Helps reduce the appearance of expression lines
  • Niacinamide — Minimizes pores, balances oil, and evens skin tone
  • Hyaluronic Acid — Draws in moisture and keeps skin hydrated
  • Panthenol — Soothes and supports your skin barrier
FAQs

Q: When do I apply this in my routine?
A: Use it right after cleansing as your first serum step, morning and night. It's designed to boost absorption of whatever you layer next.

Q: Can I use this with retinol or exfoliating acids?
A: It's best to use them at different times—try this serum in the morning and retinol or acids at night to avoid potential irritation.

Q: Is this serum suitable for oily or acne-prone skin?
A: Yes, the lightweight texture and sebum-regulating ingredients like niacinamide make this serum appropriate for oily and acne-prone skin types.

Q: How long until I see results?
A: Most users notice improved hydration and smoother texture within 2-4 weeks, while benefits like firmer-looking skin and reduced fine lines typically become more visible after 6-8 weeks of consistent use.

Q: What is the difference between this booster serum and a regular serum?
A: This booster serum is designed to be applied as the first step after cleansing to enhance the penetration and effectiveness of products applied afterward, while regular serums typically deliver concentrated active ingredients as a standalone treatment step.

Q: How should I store this serum?
A: Store in a cool, dry place away from direct sunlight. Refrigeration isn't required but can feel refreshing on application.

Q: Who should avoid using this product?
A: Those with a known allergy to any of the listed ingredients should avoid use. If you're pregnant or nursing, consult your dermatologist before adding new peptide products to your routine.

How to Use

Cleanse your face thoroughly and pat dry. Dispense 2-3 pumps or a few drops onto your fingertips. Pat the serum gently over your entire face until absorbed. For enhanced results, apply an additional layer before your next skincare step. Follow with your serum, ampoule, or moisturizer. Use twice daily, morning and evening.
