Read the Label: ARK Skincare Radiance Serum

ARK Skincare

Marketed as a serum for glow-seekers, ARK Skincare’s Radiance Serum claims to create luminous, dewy skin in an instant. The formula is said to soften and brighten while reducing the appearance of sun spots and age spots. 

Key benefits to include:

  • Amino acids brighten and evens skin tone;
  • Red algae gives skin luminosity and reduces the look of sun spots; and
  • Velvet flower seed aids in skin cell repair and regeneration.

Instructions direct users to directly apply 2–3 drops of serum to the skin, or mixed with ARK Moisturizer for a more intensive treatment.

This column will review the ingredient listing for claims substantiation and functionality.

Solvents and Formulating Aids

The water-based formula contains glycol as solvents; butylene glycol, a viscosity enhancing solvent; and propylene glycol, a humectant. Meanwhile, almond oil PEG-8 ssters serves as an emollient and emulsifier; ammonium acryloyldimethyltaurate/VP copolymer is a viscosity increasing agent; sodium hydroxide regulates pH; and disodium EDTA is a chelating agent.


Active ingredients are a stabilized form of vitamin C; ascorbyl glucoside, for even and radiant skin tone; a humectant Glycerin; Palmaria Palmata (red algae) extract rich in antioxidants; 1-Methylhydantoin-2-Imide, an amino acid derivative with skin lightening properties; and soothing Allantoin. Amaranthus Caudatus (velvet flower) seed extract adds soft, smooth feel to the formulation.

Preservatives and Fragrance

Benzyl alcohol, phenoxyethanol and dehydroacetic acid are preservatives. The formula contains fragrance with potential allergens limonene, geraniol and linalool.


In my view, the ingredients support a soft, lustrous and dewy effect of the serum to even out and brighten skin tone, and have a potential reduce the appearance of pigmentation. However, less clearly these support a broad skin cell repair and regeneration claim. The formula contains potential allergens.
