Take a closer look at our formula

Clinically proven actives in precise concentrations, designed for synergistic efficacy.

Stabilized formula Stay-C® 50

Sodium Ascorbyl Phosphate

Primary active — brightening & antioxidant protection

  • Visibly improves skin tone and radiance
  • Supports collagen production for firmer-looking skin
  • Protects against environmental stress and oxidative damage
  • 30% more effective absorption vs. standard L-Ascorbic Acid forms
Clinical note

Our formula uses Sodium Ascorbyl Phosphate (SAP), a stabilized Vitamin C derivative that converts into active ascorbic acid on the skin. Sourced as Stay-C® 50, this high-purity form enhances stability, resists oxidation, and enables gradual release for sustained antioxidant activity. Unlike L-Ascorbic Acid, SAP remains effective at a skin-friendly pH of ~5, minimizing irritation and making it suitable for sensitive skin.

Antioxidant booster

Ferulic Acid

Synergist — enhances & stabilizes actives

  • Doubles the antioxidant efficacy of Vitamins C and E
  • Maximizes brightening and anti-aging effects of the formula
  • Neutralizes free radicals for long-lasting skin defense
  • Helps prevent photoaging and hyperpigmentation
Clinical note

Studies show that combining Ferulic Acid with 15–20% Vitamin C and Vitamin E can increase photoprotection by up to 8× compared to Vitamin C alone. Ferulic Acid also stabilizes Vitamin C molecules, significantly extending the serum's active shelf life and on-skin performance.

Deep hydration complex

Hydration Power Molecule

Hydrator — plumping & skin barrier support

  • Deeply hydrates and visibly plumps skin on contact
  • Strengthens and supports a more resilient skin barrier
  • Reduces the appearance of fine lines caused by dehydration
  • Non-comedogenic — suitable for oily and acne-prone skin
  • Helps Vitamin C penetrate more effectively when skin is hydrated
Clinical note

Hyaluronic acid (HA) is an endogenous glycosaminoglycan naturally present in the skin that plays a key role in maintaining hydration and tissue integrity. Topically applied HA helps attract and retain moisture at the skin’s surface, enhancing hydration, smoothing the appearance of fine lines, and supporting a healthy-looking skin barrier. Its water-binding capacity can improve skin suppleness and overall skin comfort.

Organic

Aloe Vera · Jojoba · Centella Asiatica

Clinically proven actives in precise concentrations, designed for synergistic efficacy

  • Aloe Vera Base – Boosts absorption of all active ingredients for maximum effectiveness
  • Organic Jojoba – Mimics the skin’s natural sebum for lightweight, non-clogging hydration
  • Centella Asiatica – Soothes redness and supports natural skin repair
  • Clean, Purposeful Formula – No synthetic fillers; every ingredient has a functional role
  • Dermatologist-Tested – Gentle and safe for sensitive skin
Clinical note

Centella Asiatica contains asiaticoside and madecassoside — triterpenoid compounds shown to stimulate fibroblasts and accelerate epidermal repair. Combined with Vitamin C, Cica reduces post-active sensitivity while reinforcing the skin's own collagen network over time.
