What Does a Peptide Body Serum Actually Do?

Peptides are not just for the face

Peptides are short chains of amino acids used in many skincare formulas. Different peptides have different functions, and results depend on the specific ingredient, concentration, formula and supporting evidence. A peptide label alone is not proof of clinical results.

Why use a body serum?

A body serum is typically designed as a treatment step that can be layered under a moisturizer or oil. The goal may be hydration, a smoother appearance or targeted care for areas such as arms, chest, neck and legs.

How Signal Synq fits in

Signal Synq™ Hydrating Serum is designed for face and body. Its formula features a peptide complex, vegan PDRN and LinoRet-AF (retinyl linoleate), a vitamin A derivative. It is intended for people looking to address the appearance of dry, crepey-looking skin as part of a consistent skincare routine.

Peptide serum versus body lotion

A serum and moisturizer do different jobs. A serum may emphasize specific treatment ingredients, while a body milk or balm helps maintain skin comfort and moisture. Layer Aloura™ Skin Milk or Ekoa™ Longevity Oil over your serum if your skin needs more moisture.

What should shoppers look for?

Look for clear ingredient identification, realistic claims, directions, compatible packaging and reviews from verified purchasers. Be cautious of any product claiming that peptides can completely reverse aging or replace medical treatment.
