Do peptides really work or is it marketing?

They do work. Families such as Matrixyl, Argireline and copper peptides have published clinical studies showing wrinkle reduction, improved firmness and increased collagen. Gradual effect, more subtle than retinol, but cumulative and without contraindications.

How long does a peptide serum take to work?

Visible results between weeks 4 and 8. Argireline may show improvement on expression lines as early as week 4. Matrixyl requires 8-12 weeks for clear firmness results.

Can peptides be combined with retinol or vitamin C?

Yes, with all of them. Among the most compatible actives. With retinol they are synergistic. With vitamin C, space applications by 10-15 minutes to preserve each pH, with no incompatibility described.

Peptides or retinol: which is better?

For maximum anti-ageing efficacy: retinol. For firmness and skin that cannot tolerate irritation: peptides. Ideally combine them.

Can peptides be used during pregnancy?

Yes. Cosmetic peptides are considered safe during pregnancy and breastfeeding, alongside bakuchiol, vitamin C and niacinamide.

Which peptide is best for expression lines?

Argireline (acetyl hexapeptide-8) is the most studied. It inhibits neurotransmitter release driving muscle contraction. SNAP-8 and Leuphasyl work through similar mechanisms.
