Our formula approach

Formula clarity, without the complicated language.

Signal Serum is designed for skin that feels dry, looks dull or appears less even than usual. Its formula combines 200,000 ppm—equivalent to 20%—salmon-derived PDRN with 2% niacinamide, targeted peptides and a multi-hydration complex.

Here, we explain what each part is included to support, what the concentration means and where a cosmetic serum fits in a consistent routine.

Consumer-reported results

A focused routine can feel different after 28 days.

PDRN, explained

What is PDRN in Signal Serum?

PDRN is commonly used as an abbreviation for polydeoxyribonucleotide. In the Signal Serum ingredient declaration, the salmon-derived material is listed as Sodium DNA. UNA discloses that this ingredient is present at 200,000 ppm, equivalent to 20% of the finished formula.

This is a cosmetic formula; we do not present topical PDRN as a medical treatment.

Why the formula is paired

One formula, designed around the way skin can feel and look.

Hydration and comfort: humectants, multi-weight hydration and comfort-supporting ingredients help skin feel replenished and comfortable.

Fresh-looking radiance: salmon-derived PDRN, niacinamide and complementary formula support help dull-looking skin appear fresher.

More even-looking tone: 2% niacinamide and hydration support help maintain a brighter, balanced-looking appearance with consistent cosmetic use.
