In a clinical study published in a peer-reviewed scientific journal, BOOSTâs formula was tested directly against marine collagen. BOOST improved firmness, elasticity and hydration. Marine collagen did not.
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 it works
The supplement that outperformed collagen powder in a clinical trial.
Collagen powder
Breaks down before it reaches your skin. It dissolves into generic amino acids in your stomach â your body sends them wherever they are needed most, which is rarely your skin.
BOOST
Arrives ready to work in the dermis. Collagen, elastin, and hyaluronic acid already structured the way your skin cells recognise and use them. No reassembly. No detour through digestion.
The Formula
Precision-formulated for skin renewal from within
Aging begins in the dermis, not on the surface. Six clinically chosen actives, each targeting a different stage of the renewal process â working as one complete system.
REGGENERATEâĸ
Rebuilds the structure collagen lives in
Read more
Eggshell membrane delivers collagen, elastin, and hyaluronic acid in the form your skin uses directly. Clinically shown: +44% firmness, +39% elasticity, +40% hydration in 8 weeks.
SkinAx²Ž Lift
Activates your skin's own collagen production
Read more
Grape polyphenols and melon SOD switch on the fibroblasts that build new collagen. Where powder supplies raw material, SkinAx activates the factory that uses it.
Hyaluronic Acid
Fills the space collagen fibres live in
Read more
Low molecular weight HA reaches the dermis, holding water between collagen and elastin fibres. A cream stays on the surface. This goes where hydration is structural, not cosmetic.
Ceramides
Seals the barrier so results hold
Read more
Plant-derived ceramides reinforce the skin barrier from within, reducing moisture loss so improvements happening deeper in the dermis can accumulate over time.
Astaxanthin
Protects what you are building
Read more
One of the most potent antioxidants known. It neutralises UV and environmental stress that degrades collagen faster than your skin can replace it.
Vitamin C
The cofactor collagen cannot form without
Read more
Chemically required to stabilise the collagen triple helix. Without it, the collagen your skin produces is structurally unstable. BOOST includes it to complete the synthesis pathway.
Six actives. One complete system. Two capsules a day.

Two capsules. Not two scoops.
Made in Germany ¡ GMP certified ¡ Third-party lab tested ¡ Contains egg (eggshell membrane). Not suitable for people with an egg allergy.
Your skincare routine works from the outside in. BOOST works from the inside out, targeting the dermis, where collagen, elastin, and hydration are formed and preserved.
Creams, serums, and SPF protect and treat the surface of the skin. But they do not reach the dermis, where skin structure is built. BOOST delivers six clinically studied active ingredients to support firmness, elasticity, deep hydration, and skin barrier integrity from within.
It does not replace your skincare routine. It complements it from within, helping everything you already do work from a stronger foundation.
Clinically shown in a randomized controlled study: +44% firmness, +39% elasticity, +40% hydration in 8 weeks.
Take 2 capsules every morning, with or without food.
Results build over the first 8 weeks as the dermis remodels. To maintain improvements in firmness, elasticity, and hydration, continue taking BOOST daily. As with other nutritional support, lasting results depend on consistent use.
Recommended routine: BOOST in the morning, followed by your antioxidant serum and SPF. Support from within combined with surface protection creates more lasting results.
Contains egg, in the form of eggshell membrane. Not suitable for people with an egg allergy. Formulated for healthy adults. If you are pregnant, breastfeeding, or taking medication, consult your doctor before use.
Dermal matrix
REGGENERATEâĸ eggshell membrane ¡ 300 mg
Provides the complete structure collagen needs to form and last
Collagen powder is broken down into amino acids in the gut. REGGENERATEâĸ provides what the dermis actually needs: natural collagen, elastin, hyaluronic acid, and glycosaminoglycans, in a form the skin recognizes and can use directly. This is the structure collagen fibers rest within. Clinically shown to help support +44% firmness, +39% elasticity, and +40% hydration in 8 weeks.
Contains egg
Collagen synthesis
SkinAx²Ž Lift ¡ 200 mg
Activates collagen production at the cellular level
Collagen powder provides raw material. SkinAx²Ž Lift does something different: it activates the fibroblasts that actually build new collagen. Where powders rely on passive absorption, SkinAx²Ž Lift triggers active synthesis. It also helps protect against collagen breakdown and supports skin radiance and structure.
Dermal hydration
Hyaluronic acid ¡ 120 mg
Fills the space where collagen fibers live
Deep in the dermis, hyaluronic acid binds water between collagen and elastin fibers, giving skin density, resilience, and bounce. A hyaluronic acid cream sits on the surface. BOOST uses low-molecular-weight hyaluronic acid, selected for its ability to reach the dermis. That is where hydration becomes structural, not just cosmetic, and where it lasts.
Barrier integrity
Ceramides ¡ 30 mg
Preserves hydration while structure is rebuilt
The barrier is what prevents the dermis from losing moisture faster than BOOST can rebuild it. Plant-based ceramides replenish the lipid layer from within, reduce water loss, and help preserve the results happening deeper in the skin. A stronger barrier means better results over time.
Antioxidant protection
Astaxanthin ¡ 6 mg
Protects the collagen you build from breaking down
Building collagen matters less if oxidative stress breaks it down faster than the skin can replace it. Astaxanthin is one of the most powerful antioxidants and helps neutralize UV and environmental stress that breaks down collagen fibers. BOOST builds. Astaxanthin protects what is built.
Collagen cofactor
Vitamin C ¡ 80 mg
Without it, collagen cannot form correctly
Vitamin C is not optional for collagen synthesis. It is chemically required as a cofactor for the enzymes that stabilize collagen's triple helix. Without enough vitamin C, the collagen the skin produces becomes structurally unstable. BOOST contains vitamin C to help ensure the entire synthesis process is complete.

Frequently asked questions
How is BOOST different from collagen powder?
Collagen powder adds raw material: amino acids your body must reassemble from scratch. Most of it never reaches your skin. BOOST works on the environment that determines whether collagen can form and last. It rebuilds the dermal matrix: the elastin, hyaluronic acid, and glycosaminoglycans that collagen fibres anchor into.
Can I take BOOST instead of my collagen powder?
Yes. BOOST is designed as a direct replacement, not an addition. It stimulates your skin to produce its own collagen and gives that collagen somewhere to anchor and last. You do not need to take both.
How long until I see results?
The clinical trial ran for 2 months. Consumer perception data shows most women notice improvements to firmness, hydration, and elasticity within 6 to 8 weeks of daily use. Consistency matters more than timing.
What is Reggenerateâĸ and why does it matter?
Reggenerateâĸ (MKAREÂŽ) is a patented eggshell membrane extract studied in a 2025 double-blind randomised controlled trial published in Frontiers in Nutrition. At just 300mg, it outperformed 8g of marine collagen across all three skin measures: firmness (+44.7%), elasticity (+39.3%), and hydration (+40%). It is the primary active in BOOST.
What is SkinAx2 Liftâĸ?
SkinAx2 Liftâĸ is a clinically studied blend of two active compounds: grape polyphenols and melon-derived superoxide dismutase (SOD). Together they support collagen synthesis and protect skin cells from oxidative stress, which breaks down collagen faster than your skin can rebuild it.
How do I take BOOST?
2 capsules daily with water. No scoops, no mixing, no chalky texture. Take them at the same time each day for best results.
Is BOOST suitable for vegans?
No. BOOST contains Reggenerateâĸ, which is derived from eggshell membrane. It is not suitable for vegans or anyone with an egg allergy. Please check the full ingredient label before use.
Where is BOOST made and tested?
BOOST is manufactured in Germany to pharmaceutical-grade standards. Every batch is independently tested by a third-party laboratory for quality, purity, and label accuracy.
What does the subscription include and can I cancel?
