Syner-C+ by HydroPeptide is a multi-action vitamin C serum for skin with dark spots, dullness and uneven tone. Its formula helps reduce the appearance of existing discoloration while promoting a brighter, more even-looking complexion.

The serum contains 20% 3-O-ethyl ascorbic acid, a stable form of vitamin C that helps improve the appearance of hyperpigmentation and provides antioxidant support. This is particularly useful when skin looks dull and needs both a more even tone and renewed radiance.

Vitamin C is complemented by 1% tranexamic acid and 0.5% arbutin, which help reduce the appearance of dark spots. 5% niacinamide supports a more even-looking tone while helping maintain the skin barrier and hydration. Together, these ingredients address several aspects of visible discoloration.

The patented 5% Micellar CellRenew-16 complex supports moisture retention and helps skin look firmer. This makes the serum relevant when loss of firmness is a concern alongside dark spots.

The formula is designed to improve the skin’s overall appearance, addressing general dullness and uneven tone as well as individual spots. When used in the morning, its antioxidant action complements daily sun protection, though the serum does not replace sunscreen.

In a brand study involving 25 participants, after 12 weeks of use, overall skin tone evenness improved by 27%, visible brightness by 29%, and skin clarity by 31%. These figures describe the study group and reflect the results of consistent use.

Who is Syner-C+ for: dry and normal skin with dark spots, dullness, uneven tone or visible loss of firmness.
