Krämer och serum verkar på ytan. BOOST verkar inifrån, i dermis, där kollagen och elastin faktiskt bildas.

Diagram showing how BOOST reaches the dermis through the bloodstream, where collagen and elastin are formed

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.

Clinical evidence

Outperforms collagen.

Collagen supplements require 8–10g daily because most of it never reaches the skin. BOOST uses 300mg of targeted actives that work directly in the dermis — where collagen and elastin are formed.

In a head-to-head clinical trial, BOOST outperformed 8g marine collagen across firmness, elasticity, and hydration.

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 maintained.

Creams, serums, and SPF protect and treat the surface. But they cannot reach the dermal layer where skin structure is built. BOOST delivers six clinically studied actives to exactly that layer, supporting firmness, elasticity, deep hydration, and barrier integrity from within.

It is not a replacement for your skincare routine. It is the inside-out complement that makes everything you already do work from a stronger foundation.

Clinically shown in a randomized controlled trial: +44% firmness, +39% elasticity, +40% hydration in 8 weeks.

Take 2 capsules each morning, with or without food.

Results build over the first 8 weeks as the dermis remodels. To maintain the improvement in firmness, elasticity, and hydration, continue taking BOOST daily. Like any nutritional support, the results are sustained by consistent use.

Suggested routine: BOOST in the morning, followed by your antioxidant serum and SPF. Inside-out support combined with surface protection gives more durable results.

Contains egg (eggshell membrane). Not suitable for egg allergies. Formulated for healthy adults. If you are pregnant, nursing, or taking medication, consult your clinician before use.

Dermal Matrix

REGGENERATE™ Eggshell Membrane · 300 mg

Delivers the complete structure collagen needs to form and last

Collagen powder breaks down into amino acids in the gut. REGGENERATE™ delivers what the dermis actually needs: native collagen, elastin, hyaluronic acid, and glycosaminoglycans, in the form the skin recognises and uses directly. This is the scaffolding collagen fibres live within. Clinically shown to deliver +44% firmness, +39% elasticity, and +40% hydration in 8 weeks.

Contains egg

Collagen Synthesis

SkinAx²® Lift · 200 mg

Activates collagen production at the cellular level

Collagen powder supplies raw material. SkinAx²® Lift does something different: it activates the fibroblasts that actually build new collagen. Where powder relies on passive absorption, SkinAx²® Lift triggers active synthesis. It also protects against collagen degradation and supports skin luminosity and texture.

Dermal Hydration

Hyaluronic Acid · 120 mg

Fills the space collagen fibres live in

Deep in the dermis, hyaluronic acid holds water between collagen and elastin fibres, giving skin its density, sponginess, and bounce. A cream HA sits on the surface. BOOST uses low molecular weight HA, selected for its ability to reach the dermis. This is where hydration is structural, not just cosmetic, and where it lasts.

Barrier Integrity

Ceramides · 30 mg

Keeps hydration in while structure rebuilds

The barrier is what stops the dermis losing moisture faster than BOOST can build it. Plant-derived ceramides replenish the lipid layer from within, reducing water loss so the gains happening deeper in the skin can hold. A stronger barrier means better results over time.

Antioxidant Protection

Astaxanthin · 6 mg

Protects the collagen you are building from breaking down

Building collagen means nothing if oxidative stress degrades it faster than the skin can replace it. Astaxanthin is one of the most potent antioxidants known, neutralising the UV and environmental stress that destroys collagen fibres. BOOST builds. Astaxanthin protects what is being built.

Collagen Cofactor

Vitamin C · 80 mg

Without it, collagen cannot form properly

Vitamin C is not optional for collagen synthesis. It is chemically required as a cofactor for the enzymes that stabilise the collagen triple helix. Without adequate Vitamin C, the collagen the skin produces is structurally unstable. BOOST includes it to ensure the entire synthesis pathway is complete.

Frequently Asked Questions

BOOST is for women who want to support skin firmness, elasticity, and hydration from within - not just on the surface.

It’s especially relevant if you’re looking for a more long-term approach to skin aging, beyond creams and serums, and want to support how your skin is built over time.

It’s also ideal if collagen supplements haven’t delivered noticeable results, or if you’re investing in treatments like microneedling, laser, or peels and want to support how your skin rebuilds.

Collagen powders are broken down during digestion into amino acids and used throughout the body - not specifically for skin.

BOOST works differently.

It combines targeted actives that work in the dermis , where collagen and elastin are formed. This supports the systems that keep skin firm, elastic, and hydrated.

In a head-to-head 8-week clinical trial, BOOST outperformed 8g of marine collagen on elasticity, firmness, and hydration.

Because what is inside it costs more to make.

Most collagen supplements are bulk amino acids - commodity ingredients produced at scale. The cost is low because the formulation is simple.

BOOST is built around two patented actives: REGGENERATE™ and SkinAx²® Lift. Both are licensed, clinically studied compounds that cost significantly more than standard collagen protein. They are not interchangeable with cheaper alternatives. That is by design.

The formula is also a precision blend. Six actives targeting collagen structure, hydration, barrier function, and antioxidant protection in one daily dose. Developing and manufacturing that combination to pharmaceutical-grade standards in Germany adds cost that a single-ingredient powder does not have.

The result: in a head-to-head randomized trial, 300mg of REGGENERATE™ outperformed 8g of marine collagen across firmness, elasticity, and hydration. Two capsules beat two scoops.

You are not paying for more. You are paying for something that works differently.

Yes. BOOST works alongside your skincare, not instead of it.

Creams and serums act on the surface of the skin.

BOOST works from within, supporting the dermis where collagen and elastin are formed. A layer topicals can’t meaningfully reach.

Think of it as supporting the layer your skincare can’t.

Both support skin renewal but through different mechanisms.

Retinol works topically - accelerating cell turnover at the surface.

BOOST works from within - supporting collagen and elastin formation in the dermis and strengthening the skin barrier with ceramides and hyaluronic acid.

Many people use both: retinol handles surface renewal, BOOST handles structural support from within. And because BOOST supports the skin barrier, it can help counteract the dryness and sensitivity retinol sometimes causes.

Yes - microneedling creates a 12-week collagen remodeling phase, where your skin actively rebuilds.

BOOST supports this process from within, helping support collagen, elasticity, and hydration in the dermis - where skin structure is restored after treatment.

BOOST combines REGGENERATE™, SkinAx²® Lift, hyaluronic acid, ceramides, astaxanthin, vitamin C, and zinc.

Together, they support the key systems behind healthy skin - structure, elasticity, hydration, and barrier function.

Clinical results were measured at 8 weeks.

Most users notice improvements in hydration and skin texture within 4 weeks, with visible improvements in glow and overall skin quality by 8 weeks.

Take 2 capsules daily with or without food. Morning is ideal as part of your daily skincare routine, helping support your skin as it faces daily environmental stressors.
