Hibiscus Extract
The antioxidant power
Antioxidant-rich, Hibiscus helps counter the oxidative stress that contributes to brittleness, dullness, and slow recovery. Especially powerful after gel or acrylic removal.

Inside the 12%.
Powered by peptides. Proven to transform.
Every ingredient in Peptide Serum Concentrate was chosen for a reason. Four ingredient stories layer into one supercharged formula, so every drop delivers strength, antioxidant power, and deep hydration at once.
Aloe + Glycerin + D-Panthenol
The moisture trio
Aloe cools and soothes stressed cuticles on contact. Glycerin draws hydration in. D-Panthenol supports the nail's natural moisture barrier so cuticles stay supple, never dry.
Water-Based Gel Technology
The delivery system
A weightless, water-based gel that absorbs in seconds, delivering 12% actives directly to where new nail growth begins. Fast-acting, fully absorbed, never greasy.
Cranberry Peptides
The structural core
Cranberry-derived peptides reinforce nail structure at the base and support flexibility, so nails grow in stronger and bend before they break.

Frequently Asked Questions
How is Peptide Serum Concentrate different from cuticle oil?
Cuticle oil sits on the surface to lock in moisture. Peptide Serum Concentrate is a water-based serum that absorbs in seconds, delivering 12% actives directly to the cuticle base. Oil seals; this rebuilds. They work beautifully together: serum first, oil second.
Can I use it on polished or gel nails?
Yes. Apply one drop to each cuticle area and massage in. If your nails are polished, apply to the cuticle only. The formula is designed to be used around the cuticle area.
How often should I use it, and when will I see results?
Three times a week is the recommended frequency, or daily if your nails are extra dry or recovering from acrylics or gel. Individual results vary; follow the product directions consistently.
