Quick Answer
- Salmon DNA: Purified fish DNA focused on skin repair and skin quality
- Hyaluronic acid skin injectables: Lab-made hyaluronic acid focused on hydration
- Volume: Neither adds volume like a filler
- Results: Hyaluronic acid shows hydration sooner. Salmon DNA builds gradually.
- Fish allergy: Rules out salmon DNA, not hyaluronic acid
What Are the Two Treatments?
Salmon DNA treatment uses purified DNA fragments from salmon or trout, known as PDRN or polynucleotides. The product supports the skin’s own repair process.
Hyaluronic acid skin injectables use a thin, lightly or non-cross-linked form of hyaluronic acid. Hyaluronic acid attracts and holds water in the skin. These injectables spread across the skin in small amounts to improve hydration and glow.
How Do They Work Differently?
- Salmon DNA sends repair signals to skin cells, calms inflammation and supports fibroblasts. Fibroblasts produce collagen and elastin.
- Hyaluronic acid draws water into the skin and holds the water in place. This improves hydration and surface smoothness.
In short, salmon DNA works on skin health. Hyaluronic acid works on skin hydration.

Which Should You Choose?
- Choose salmon DNA if your main concern is crepey or thin skin, sensitivity, redness or recovery after laser.
- Choose hyaluronic acid if your main concern is dehydration and dullness, or if you have a fish allergy.
- Combine both if you want repair and hydration together. Doctors often alternate the two within one plan.
Your doctor recommends a plan after assessing your skin.
