RejuvaJoy

Skin Renewal & Radiance, Without Compromise

Beauty-from-within support built entirely from clinically-studied, branded ingredients — dosed the way the research actually intended.

Real skin health starts beneath the surface. The collagen that keeps skin firm, the hyaluronic acid that holds its moisture, the ceramides that lock in hydration, the antioxidants that even out tone, and the soothing lipids that calm reactivity — plus the vitamin C your body needs to build collagen in the first place. Most beauty supplements give you a token scoop of generic collagen and stop there. RejuvaJoy delivers the whole picture — premium, clinically-studied branded actives at the doses the research actually used. No filler. No compromise.

What's Inside — and Why It Matters

Hydrolyzed Collagen Peptides 10 g (VERISOL® by GELITA — Germany) Not generic collagen — VERISOL® is a specific collagen peptide engineered and studied specifically for skin. The rationale is mechanistic: orally-ingested collagen peptides are broken down into characteristic small di- and tri-peptides (like prolyl-hydroxyproline) that are absorbed into the bloodstream, and the thinking is that these peptides act as signalling fragments — effectively mimicking the breakdown products of aged collagen, which prompts the skin's fibroblasts to ramp up their own production of collagen, elastin and hyaluronic acid. VERISOL® has been studied in randomized, placebo-controlled trials on skin elasticity, the appearance of eye wrinkles, and skin moisture, with the research using daily doses in the 2.5 g range over roughly 8 weeks — and at 10 g, RejuvaJoy supplies a generous dose. From the company that pioneered bioactive collagen peptides.

Vitamin C 2,000 mg (Ester-C® by The Ester C Company — USA) Vitamin C isn't optional for skin — it's an essential, non-negotiable cofactor for the enzymes that build collagen. Specifically, the enzymes that stabilise the collagen triple helix (prolyl and lysyl hydroxylase) cannot function without it; deprive the body of vitamin C and it literally cannot form stable, mature collagen. That's why this is the one ingredient here with a genuine EU-authorized claim: vitamin C "contributes to normal collagen formation for the normal function of the skin." It's also a potent antioxidant that helps regenerate other antioxidants and protect skin cells from oxidative stress. Pairing it with collagen peptides is deliberate — you're supplying both the raw building blocks and the cofactor the body needs to assemble them. Ester-C® is a gentle, pH-neutral, non-acidic form, easier on the stomach than ordinary ascorbic acid and known for extended retention.

Hyaluronic Acid 150 mg (Hyabest® by Kewpie — Japan) The molecule that lets skin hold water — a single gram of hyaluronic acid can bind a remarkable amount of it, and it's a major component of the skin's own moisture-retaining matrix. The mechanism for oral HA is an active research area: ingested hyaluronic acid is broken into smaller fragments that are absorbed and distributed through the body, and studies suggest these fragments both contribute to the body's HA pool and may signal skin fibroblasts to produce more of their own HA. Oral HA has been studied for supporting skin hydration and reducing the appearance of the fine, dryness-related lines that show up when skin loses moisture, typically over 8–12 weeks of daily use. Hyabest® by Kewpie is a high-purity, clinically-studied oral hyaluronic acid from a global leader in HA production.

Ceramides 30 mg (Ceramosides® by Seppic — France) A standout, clinically-studied active that works on the skin's barrier. Ceramides are the lipids that hold the outermost skin layer together — picture the skin barrier as a brick wall, with skin cells as the bricks and ceramides as the mortar holding them in place. Ceramides naturally decline with age, which is part of why mature skin loses water and feels drier and tighter. Ceramosides® is a wheat-derived ceramide complex shown in clinical research to improve skin moisture and elasticity at a 30 mg daily dose, with studies also reporting improvement in the appearance of wrinkles — the mechanism being that supplying ceramides helps rebuild that "mortar" from within, so the barrier holds water more effectively and the skin's surface stays smoother. A genuinely barrier-targeted active, at the exact 30 mg dose used in its research.

Fermented Wild Bilberry Extract 100 mg (Sepitone™ by Seppic — France) A radiance-and-tone active, and one of the more distinctive inclusions here. Sepitone™ is a fermented wild bilberry extract, exceptionally rich in proanthocyanidins — the deep-coloured polyphenol antioxidants that berries are prized for. The rationale is antioxidant and microcirculatory: proanthocyanidins are potent quenchers of the oxidative stress that dulls and ages skin, and the research literature links them to benefits for collagen, skin elasticity and blood circulation. In Seppic's clinical work, Sepitone™ was studied in randomized, double-blind, placebo-controlled trials — first in 60 women with dull skin, where it was associated with improvements in skin colour, evenness of tone, skin roughness and the harmonisation of skin microcirculation; and in a later trial in women aged 35–65 with visible signs of ageing, where it was reported to reduce wrinkle depth by around 14% and improve skin firmness and elasticity by around 13%. A glow-and-evenness active that complements the formula's structural and hydration ingredients.

Coriander Seed Extract 200 mg (Sepibliss™ powder by Seppic — France) A newer, genuinely differentiated active — the first nutraceutical ingredient developed specifically for sensitive, reactive skin, and one of the better-characterised in terms of mechanism. Sepibliss™ is derived from coriander seed and built around an unusual fatty acid it's exceptionally rich in: petroselinic acid. In laboratory research, coriander seed oil was shown to act on two specific pathways behind sensitive skin — calming inflammatory signalling (the NF-κB pathway) and dialing down the over-firing of the nerve-sensation receptors (the TRPA1 pathway) that drive stinging and discomfort. That mechanism then held up in people: in a randomized, double-blind, placebo-controlled trial in 60 women with sensitive skin taking a 200 mg daily dose for 56 days, the coriander group showed reduced skin reactivity to mechanical and chemical stress, with further Seppic research reporting soothing and protective effects. Included here in the powder form, so it blends cleanly with the other actives. A soothing, resilience-building active that most beauty formulas don't address at all. (Note: coriander has a pending EU skin-related health claim, not yet authorized.)

Why RejuvaJoy Is Different

✓ 100% branded actives — VERISOL®, Ester-C®, Hyabest®, Ceramosides®, Sepitone®, Sepibliss™ ✓ Clinically-relevant doses — a full 10 g of collagen, and the exact 30 mg / 100 mg / 200 mg doses used in the ceramide, bilberry and coriander research ✓ The complete picture — build (collagen + vitamin C), hydrate (HA + ceramides), brighten (bilberry), and soothe (coriander) ✓ Two dimensions most formulas ignore — radiance/even tone, and support for sensitive, reactive skin ✓ No proprietary blends — every milligram is on the label

The Synergy That Sets It Apart

RejuvaJoy supports skin the way skin is actually built and maintained. VERISOL® collagen peptides supply the signalling peptides that prompt firmness and elasticity — and Ester-C® provides the vitamin C the body requires to turn those into stable collagen, so the two work as a deliberate pair. Hyabest® hyaluronic acid and Ceramosides® ceramides then handle moisture from two directions: HA holds water within the skin, while ceramides rebuild the barrier "mortar" that stops it escaping. Sepitone® bilberry layers in antioxidant and microcirculatory support for tone and radiance, and Sepibliss™ coriander calms the inflammatory and nerve-signalling pathways behind sensitive, reactive skin. Build, hydrate, brighten, and soothe — in one daily formula.

Who It's For

Anyone who wants to support their skin from the inside out — firmness, hydration, radiance, resilience, and calm. People noticing the first signs of aging and wanting to act early, those further along who want meaningful research-backed support, anyone chasing a brighter, more even complexion, and — distinctively — anyone with sensitive or reactive skinwho's been left out by formulas that only chase wrinkles. Anyone who's bought a pretty collagen tub, checked the dose, and realized it was a fraction of what the studies actually used.

Simple to Take. Built to Last.

Take daily as directed. Skin renewal is a gradual process tied to the skin's own renewal cycle — the clinical studies behind these ingredients ran over 8 weeks and beyond of consistent daily use. Make RejuvaJoy part of your routine and give it time to show.

Beautiful skin is built from within. Give it everything it needs.
