Made in Germany ¡ GMP certified ¡ Third-party lab tested ¡ Contains egg (eggshell membrane). Not suitable for those with an egg allergy.
Inside-out skin renewal. Clinically proven.
BOOST works where creams cannot reach, inside the living layers of the skin.
Two capsules each morning deliver clinically studied actives to the epidermis and dermis, the layers that support collagen formation, hydration and skin structure, while helping reinforce the surface barrier and antioxidant defenses.
The result is stronger foundations for firmer, smoother, more luminous skin.
What BOOST supports
As an all-in-one inside-out solution, BOOST supports key pillars of skin health:
- Collagen formation. Supports firmness and elasticity
- Hydration balance. Helps replenish moisture and reduce water loss (TEWL)
- Barrier strength. Reinforces the skinâs protective layer
- Antioxidant defense. Helps protect against daily oxidative stress
What you can expect
In a randomized controlled trial, users saw +39% elasticity, +44% firmness and +40% hydration in 8 weeks.
With consistent daily use, skin feels more hydrated.
Elasticity and firmness improve, fine lines appear softer, and tone looks more even over time.
How it fits into your routine
BOOST is designed to work with your routine, not replace it.
BOOST â antioxidant serum â SPF
Build from within. Protect at the surface.
Recommended Use
How to take
Take 2 capsules each morning.
You can take BOOST with or without food. For better uptake of fat-soluble actives such as astaxanthin and ceramides, take it with a small amount of healthy fat such as yogurt, avocado, or nut butter.
Why morning
Daytime exposure includes UV, pollution, and blue light.
A morning dose helps support antioxidant defenses ahead of these stressors. [5â7]
Pair with your routine
Use BOOST alongside your skincare:
BOOST â antioxidant serum â SPF
Inside-out support combined with surface protection supports more durable results.
Daily routine (AM)
Eat a meal with protein and healthy fat
Keep added sugar low
Follow with serum and SPF
System approach
For a full inside-out routine:
- BOOST (AM) supports collagen, hydration, and barrier function
- VITALIZE (AM) supports cellular energy pathways
- RENEW (PM) supports overnight repair
Good to know
Contains egg (eggshell membrane).
Formulated for healthy adults. If you are pregnant, nursing, or taking medication, consult your clinician before use.
Do not exceed the recommended daily dose.
Food supplements should not replace a varied diet and healthy lifestyle.
Keep out of reach of children.
Store in a cool, dry place away from sunlight.
Clinically studied ingredients targeting the dermis
BOOST is built around ingredients that act within the dermis, where collagen, hydration and skin structure are formed.

- Dermal water binding
- Skin hydration and elasticity
- Barrier function
Strengthen the skin barrier
Ceramides - 30 mg
Plant-derived ceramides that help replenish the skin's lipid layer.
Supports:
- Barrier integrity
- Reduction in TEWL
- Protection of collagen and dermal structures
Protect against oxidative stress
Astaxanthin - 6 mg
Carotenoid antioxidant that helps protect skin from environmental stressors.

Why it builds over time
By acting within the dermis, BOOST supports ongoing collagen maintenance, hydration dynamics and barrier integrity.
The 8-week trial reflects the time needed for meaningful dermal remodelling. This is not a surface fix.
With consistent daily use, improvements build progressively over time.

Frontiers in Nutrition ¡ 2025 ¡ Double-blind RCT
Clinically proven to outperform marine collagen
In an independent randomized controlled trial, 2 capsules of BOOST were tested against 8g of marine collagen daily over 8 weeks. BOOST improved firmness, elasticity, and hydration. Marine collagen did not.
Marine collagen showed no meaningful improvement in firmness or hydration. Elasticity improved by 6.5% â compared to +39% for BOOST.

Why inside-out works differently
Topicals work on the surface. Skin structure is built deeper.
Creams and serums act on the epidermis - the outer layer of skin. That's as far as they go.
Collagen and elastin are formed in the dermis, deeper in the skin. No topical can reach it. That's not a formula problem. It's a physical limitation of the skin.
BOOST works from within. Delivered through the bloodstream, it reaches the dermis directly, where skin structure is actually built.
