EVIK™ LyoPearl Ascorbic Acid
A precision freeze-dried skincare bead designed to deliver a high-concentration ascorbic acid formulation in a stable, single-dose format.
How to Use
Each LyoPearl is designed as a simple, single-dose format that dissolves immediately before application.
Dissolve
Place one bead directly onto clean, damp skin or onto a few drops of water or skincare serum in the palm of the hand.
Apply
Gently rub the dissolved bead into the skin until fully absorbed.
Store
After each use, close the vial cap tightly and return the vial to its desiccant pouch. Keep at room temperature, away from moisture and direct sunlight.
Formulation Chemistry
L-ascorbic acid is a weak diprotic acid (pKa1 4.17). On dissolution in water the bead produces a mildly acidic solution consistent with the pH range at which ascorbic acid is most stable and demonstrates optimal skin permeation (pH 2.5–3.5; Pinnell et al., 2001).
The sodium hyaluronate co-active provides an aqueous humectant matrix on dissolution that may support ascorbic acid skin residence time.
The current EVIK™ LyoPearl Ascorbic Acid formula does not include ferulic acid or tocopherol. The literature establishes that ferulic acid provides synergistic photoprotection and stability enhancement for ascorbic acid formulations (Lin et al., 2005).
Custom formulations incorporating ferulic acid, tocopherol, or additional co-actives are available through Evik Diagnostics.
Formulation Highlights
High-concentration L-ascorbic acid at 82.7% dry weight.
Sodium hyaluronate provides a humectant co-active matrix upon dissolution.
Freeze-dried spherical bead format supports a stable, single-dose delivery system.
Custom co-active combinations can be developed according to formulation requirements.
Colour & Storage Indicator
Bead colour should be white to off-white. Any yellowing or browning indicates oxidation. Store with desiccant and discard oxidised beads.
