Peptides

Shop peptide skincare at Rover Island. Peptides are short chains of amino acids used in serums, creams and eye care for skin that looks firmer and smoother, and they are gentle enough for most skin types. Find them in ranges such as medicube PDRN Pink, numbuzin No.9 and No.2, Dr. Althea, Pyunkang Yul and Cetaphil Deep Hydration.

What Are Peptides in Skincare?

Peptides are short chains of amino acids, the building blocks of proteins such as collagen. In skincare they help skin look firmer and smoother, and they are often combined with PDRN, NAD+, ceramides or retinoids.

Why People Choose Them

Peptides are gentle, so they suit people who want to focus on firmness and fine lines without the adjustment period that retinol can bring. They work well morning and night.

How to Use Peptides

  • In a serum: after toner and before moisturizer.
  • In a cream: as your last step at night or under sunscreen in the morning.
  • Around the eyes: use an eye cream or patches made for that area.

Good Pairings

Retinol at night, vitamin C in the morning and hyaluronic acid for hydration. Avoid applying them in the same step as strong exfoliating acids.
