TOSOWOONG Copper Peptide Face Serum 33ml – 1,000ppm GHK-Cu, 12-Peptide Anti-Aging Hydrating Serum

TOSOWOONG Copper Peptide Face Serum is a lightweight Korean skin serum featuring 1,000ppm high-purity GHK-Cu and a 12-peptide complex to help visibly firm, hydrate, and smooth aging skin.

This serum blends a concentrated copper tripeptide (GHK-Cu) with multiple supportive peptides, hyaluronic acid, and a multi-collagen complex to target the common signs of aging: fine lines, loss of elasticity, and surface roughness. The formula is designed for daily use under moisturizers or oils and is presented in a 33 ml (1.11 fl. oz.) bottle suitable for a regular anti-aging routine. Lightweight and fast-absorbing, it layers well with serums and sunscreens typical in Korean skincare regimens.

How does the copper peptide in this serum work on mature skin?

The serum contains low-molecular-weight Copper Tripeptide-1 (GHK-Cu) at high purity and concentration, formulated to reach deeper skin layers more effectively. Rather than promising cures, the ingredient aims to support skin’s natural structural proteins and resilience for a firmer appearance over time.

• 1,000ppm GHK-Cu (high-purity copper tripeptide)
• Low molecular weight for better skin penetration
• Designed to promote collagen and elastin support
• Gentle concentration suited for repeated daily use

What results can I expect and when will I notice changes?

Visible improvements depend on skin type and consistency of use; many users report smoother texture and better hydration within a few weeks of regular application. Over longer periods, the peptide-rich blend targets the visual signs of sagging and fine lines while maintaining skin’s moisture and plumpness.

• Short-term: increased hydration and a dewy finish
• Medium-term: smoother skin texture and reduced look of fine lines
• Long-term: improved firmness and elasticity appearance with continuous use

How should I incorporate this serum into my routine?

Apply the serum after cleansing and any water-based toners or essences, then follow with moisturizers and sunscreen in the morning or heavier creams at night. A pea-sized amount is enough for face and neck; gently pat the formula into skin until fully absorbed to maximize peptide delivery without pilling.

• Use morning and/or night after cleansing and hydrating steps
• Apply a pea-sized portion to face and neck; pat to absorb
• Layer under moisturizers and SPF for daytime protection
• Avoid mixing with high-strength vitamin C at the same moment; separate applications if desired

Is this copper peptide serum suitable for sensitive or oily skin?

The lightweight, non-greasy texture is formulated to work across sensitive, oily, dry, and combination skin types. The concentration aims to balance effectiveness with tolerability, but patch testing is recommended if you have known sensitivities or are using active prescriptions.

• Light texture absorbs quickly without leaving heavy residue
• Formulated to hydrate without clogging pores
• Suitable for layering into multi-step skincare routines
• Patch test if you have reactive skin or use retinoids
