Frequently asked questions

Have a question? Here are the answers our customers ask most,

Asterwood's Copper Peptides Firming Serum contains GHK-Cu (Copper Tripeptide-1) and Hyaluronic Acid in a minimalist 6-ingredient formula — no fillers, fragrances, or unnecessary additives. Copper Tripeptide-1 is a reparative peptide that helps protect skin from damage, encourages collagen production, and draws moisture back to skin. The result is a firmer, more hydrated complexion with visibly fewer fine lines.
Yes — copper peptides are one of the most popular anti-aging ingredients for men because GHK-Cu targets skin elasticity, firmness, and overall skin repair rather than cosmetic concerns alone. Asterwood's formula is fragrance-free and contains only 6 ingredients, making it easy to add to a simple routine. It's a good entry point for anyone new to active skincare.
Asterwood recommends this serum for use day or night. Apply a small amount to clean, dry skin and gently massage in, then follow with moisturizer. It layers well with Hyaluronic Acid and peptide serums like Asterwood's Matrixyl 3000 + Argireline Serum. Avoid using copper peptides at the same time as direct Vitamin C or strong acids — alternate routines (morning vs. evening) for best results.
They work through different mechanisms. Retinol accelerates cell turnover but can cause irritation, peeling, and sun sensitivity. Copper peptides (GHK-Cu) support collagen production and skin repair without those side effects. For people with sensitive skin or those who can't tolerate retinol, copper peptides offer a gentler path to firmer, smoother skin. Some people alternate both in their routine for complementary benefits.
Most users notice improved skin texture and hydration within 4 to 6 weeks of consistent daily use. Visible improvements in firmness and fine lines typically develop over 8 to 12 weeks, since collagen remodeling is a gradual process. Consistency matters more than frequency — daily use will deliver better results than occasional application.
The formula contains only 6 ingredients and is free of parabens, sulfates, dyes, fragrances, and essential oils, making it well-suited for most skin types. Asterwood recommends patch testing on the neck before applying to your face if you have particularly sensitive or reactive skin. If you're looking for a gentler anti-aging option, Asterwood's Bakuchiol Smoothing Serum is a plant-based retinol alternative designed for sensitive skin.
