Explore the science behind the glow.

1. Marine Minerals (The Foundation)

Found in: Sea Foam Cleanser, Radiance Gel Face Wash

The Source: Purified minerals extracted from deep-sea waters.
The Benefit: These essential minerals, Magnesium, Calcium, and Potassium, act as natural electrolytes for your skin. They help:

Recharge and strengthen the skin barrier.
Balance natural oil production.
Ensure your skin feels refreshed and soft, never tight or stripped.

2. Sea Peptides (The Plumper)

Found in: Lip Quench Balm

The Source: Bio-available peptides derived from marine proteins.
The Benefit: Unlike traditional waxes that just sit on the surface, sea peptides penetrate the delicate lip area to:

Support natural collagen and moisture retention.
Provide a visible "plumping" effect for a fuller pout.
Smooth out fine lines for a cushiony, hydrated finish.

3. Marine Algae & Kelp (The Hydrators)

Found in: Dew Serum, Tide Cream

The Source: Sustainably harvested brown and green sea algae.
The Benefit: Known as "moisture magnets," these ocean extracts:

Create a weightless, breathable film to lock in 24-hour hydration.
Naturally calm redness and soothe irritation from environmental stress.
Deliver a mineral-rich boost for a healthy, dewy complexion.

4. Hyaluronic Acid (The Moisture Reservoir)

5. Mandelic Acid (The Gentle Refiner)

Found in: Radiance Gel Face Wash

Brightening dark spots and evening out skin tone.
Safe use on sensitive and reactive skin types.
