Frequently Asked Questions

What do peptides do for the skin?

Peptides are amino acid chains that signal the skin to support collagen and elastin, helping it look firmer, smoother and more elastic while softening the appearance of fine lines.

Are peptides good for all ages?

Yes. Peptides work well for preventative care in your 20s and 30s and for visible firming support in your 40s and beyond. They're gentle enough for most skin types.

Can I use peptides with retinol?

Yes. Peptides pair well with retinol and can help support the skin barrier while retinol works. Introduce retinol gradually and always use sunscreen during the day.

How long do peptides take to work?

Peptides work gradually. With consistent daily use, many people notice firmer, smoother skin over 4 to 8 weeks, with continued improvement over a few months.

What's the difference between peptides and collagen?

Collagen is a large protein that supports skin structure, while peptides are smaller fragments that can signal the skin to support its own collagen. They complement each other well.
