When to Use Peptides?

When should I use peptides? If you're using a peptide serum, apply it post-cleanse and before moisturising, and if you're getting your peptide fix via a moisturiser, ensure that the serum before it (if you're using one), doesn't contain a potentially aggravating active ingredient if your skin is reactive.

Do you use peptides before or after retinol?

Note: Retinols make your skin more sun-sensitive, so apply at bedtime and wear sunscreen during the day; use a peptide cream in the morning after cleansing.

What should you not use peptides with?

Choose your other ingredients wisely.

Peptides work well in tandem with other ingredients, including vitamin C, niacinamide (but don't use niacinamide and vitamin C together!), antioxidants, and hyaluronic acids. Using a peptide with an alpha hydroxy acid (AHA) will actually make the peptides work less efficiently.
