the one who seeks beauty that swims deeper

All collagen is not created equal. For skin that wants to feel firmer, smoother, and more supported — marine collagen speaks your body’s language.


The Promise — and Problem — With Collagen

Collagen has become a staple in beauty and wellness circles. But if you’ve ever taken a supplement and wondered why the results didn’t match the claims, you’re not alone.

The truth is: sourcing matters.
Not all collagen delivers the same level of absorption or skin-specific benefits — and many formulas fall short because they’re not optimized for how your body changes with age.

For women over 50, choosing the right type of collagen is the difference between hopeful effort and visible support.

The Difference Begins at the Source

Bovine Collagen

Sourced from cows, bovine collagen is typically composed of Type I and Type III collagen — supportive for joints, bones, and general structure. While it has value, the particle size is larger and the absorption less efficient.

Bovine collagen can be harder to digest and may take longer to translate into visible skin benefits, especially as digestion naturally slows with age.

Marine Collagen

Derived from wild-caught fish, marine collagen is rich in Type I collagen — the most abundant form found in human skin.

Its peptides are smaller and more bioavailable, which means they’re absorbed more easily and work faster to support:

  • Skin elasticity and firmness

  • Hydration and glow

  • Reduction in fine lines and visible aging

And for those navigating hormonal skin changes, this matters. A lot.

Why Marine Collagen Is Ideal for Women Over 50

After menopause, collagen production declines sharply — up to 30% in the first five years alone1. Skin becomes thinner, drier, and less resilient. Supporting collagen levels at this stage isn’t just cosmetic — it’s foundational.

Marine collagen offers two critical advantages:

  1. Faster Absorption: Its smaller peptides bypass digestion more efficiently

  2. Skin Targeted: Type I collagen focuses on skin structure and hydration

Collagène by THREE: A Daily Ritual for Skin Support

Our Collagène formula is more than a trend — it’s a clinical-grade, ocean-sourced ritual that honors skin from the inside out.

Each sachet delivers:

  • 5 grams of hydrolyzed marine collagen for firming and glow

  • Vitamin C to enhance collagen synthesis

  • Hyaluronic acid for deep hydration

  • Biotin + Keratin to support skin, hair, and nails

  • Pomegranate extract to encourage natural collagen production

It’s not just a supplement. It’s a signal to your skin that you’re still listening.

When to Begin

  • If your skin feels thinner, looser, or more delicate than it once did

  • If topical serums no longer feel like enough

  • If you want your glow to come from beneath the surface — where real radiance begins

Feel Radiant in the Skin You’ve Earned

Supporting your skin in your 50s and beyond isn’t about chasing youth.
It’s about honoring change with wisdom — and choosing ingredients that understand the nuance of aging well.
