What is Glowin'UP?
Glowin'UP is a dietary supplement from the Nutrivi brand (WellU Group), in the form of a powder dissolved in water, complemented by a capsule containing L-proline. Its main purpose is to support the condition of skin, hair and nails from within — by delivering peptide fractions from marine collagen along with ingredients that support the body's own collagen synthesis in tissue.
What sets Glowin'UP apart from typical collagen supplements available in pharmacies is primarily the form of collagen used (a lyophilizate, not a hydrolysate) and the accompanying premium-grade active ingredients — resveratrol, coenzyme Q10 and Centella asiatica extract.
Glowin'UP uses lyophilized marine collagen, not hydrolyzed collagen. Lyophilization (low-temperature freeze-drying) preserves delicate signalling peptides, which enzymatic hydrolysis can damage. This is the same method used in other WellU products.
The complete Glowin'UP formula — what and why
The manufacturer split Glowin'UP into two elements taken together: a powder (the peptide base and antioxidants) and a capsule (L-proline, an amino acid essential for building collagen). Below are the key ingredients with an explanation of each one's role.
The main active ingredient
Obtained from freshwater fish skins using lyophilization. Contains signalling peptides from lumican, decorin and histone fractions — the same fractions found across the entire WellU line. They stimulate fibroblasts to produce the body's own collagen and elastin.
Building-block amino acids for collagen
Glycine, lysine and proline are the three main amino acids forming collagen's triple helix. Without sufficient amounts of them, the body cannot synthesize new fibres, even if fibroblasts are active.
Supporting collagen synthesis
Centella asiatica is one of the most extensively studied plants in the context of collagen synthesis — it contains asiaticoside, which stimulates fibroblasts. Astragalus membranaceus supports regeneration at the cellular level and is known for its adaptogenic effects.
Antioxidant complex
Free radicals destroy existing collagen fibres faster than the body can produce them. This set of antioxidants neutralizes oxidative stress — particularly coenzyme Q10 (mitochondrial protection) and resveratrol (grape extract, standardized to 50% content).
Vitamin C is essential for the hydroxylation of proline — without it, collagen chains cannot properly form the triple helix. The rosehip extract in Glowin'UP is standardized to 70% vitamin C.
Hydration and condition of skin appendages
Hyaluronic acid binds water in the dermis (1 g of HA can bind up to 6 litres of water). Biotin and horsetail extract (standardized to 70% silica) support keratin — the building block of hair and nails.
How to use Glowin'UP?
The manufacturer recommends dissolving 4.76 g of powder (3 scoops) in 150 ml of water, stirring, and drinking immediately after preparation, then taking 1 capsule with L-proline with water. Important: don't mix with hot or warm water — high temperature destroys delicate signalling peptides and partly converts collagen into gelatine.
Glowin'UP is best taken in the morning on an empty stomach or 30 minutes before a meal — that way amino acids are absorbed without competing with proteins from food. Don't mix it with citrus juice (it destroys resveratrol).
How long does it take to see results?
Collagen is a structural protein — rebuilding it is a biological process that takes time. Based on manufacturer data and general knowledge about collagen supplementation, you can expect:
| Duration of use | Expected effects |
|---|---|
| 2–4 weeks | Improved skin hydration, better elasticity |
| 4–8 weeks | Stronger nails, less hair breakage |
| 8–12 weeks | Visible improvement in skin density and firmness |
| 3–6 months | Full anti-aging effects, improved tone and radiance |
Dietary supplements are not medicine and do not replace a balanced diet. Individual results may vary.
Glowin'UP and Larens cosmeceutics — is it worth combining them?
Yes — and this is exactly the philosophy behind the WellU brands. Glowin'UP delivers marine collagen peptides from within (orally), while Biopeptide Serum Spray or Larens Lifting Face Cream work from the outside — through the skin. Both are built on the same Biopeptide Complex, meaning the fibroblast-stimulating mechanisms complement rather than duplicate each other.
In practice: a morning serving of Glowin'UP + an evening Larens serum is the simplest way to build a routine that combines both channels of action of WellU's marine collagen peptides.
