The 800Da Secret: Why Molecular Size Decides Whether Collagen Works

Not all collagen is created equal. The difference between collagen that transforms skin and collagen that passes straight through comes down to one number: molecular weight. Gisbuer's BeauTe Up uses 800Da small-molecule fish collagen — the size skin actually wants.

800Da Collagen: The "Soft Gold" of Anti-Aging

Skin needs Type I and Type III collagen — and fish-skin collagen is the closest match to human collagen in amino-acid composition. Its molecular weight is small enough to be absorbed directly through the intestinal wall into the bloodstream, giving it a bioavailability around 15 times higher than other collagens.

With high concentrations of glycine, hydroxyproline and hydroxylysine, 800Da peptides enter the blood directly, stimulate cell activation, and promote the body's own collagen synthesis — for lasting firmness.

Astaxanthin: The Strongest Natural Antioxidant

Astaxanthin is the world's most powerful natural antioxidant, with the ability to enhance cellular regeneration. It controls and neutralizes multiple free radicals — and unlike other antioxidants, it never becomes a pro-oxidant itself. Gisbuer extracts it from natural Haematococcus pluvialis using ultra-fine cell-wall-breaking technology for high-purity release.

Cranberry: The Ruby of Women's Health

Rich in vitamin C, flavonoids and pectin, cranberry supports beauty and digestion while helping flush toxins and excess fat. Known as "the ruby of women's health," it protects intimate wellness, prevents urinary tract infection, fights H. pylori, supports cardiovascular health and aids antioxidation.

Sialic Acid: The Collagen Synthesis Accelerator

Present as N-acetylneuraminic acid, sialic acid promotes collagen production and reduces enzyme activity across corneal, cartilage, skin-fibroblast and epidermal cells — delivering anti-aging and beautifying effects from within.

Who It's For

Designed for adults 18+ — especially busy professionals who can't give up takeout, night-owl workers, and young mothers who want to preserve their collagen against glycation and oxidation. If you have rough, dull, or sagging skin, enlarged pores, visible wrinkles, or brittle nails, BeauTe Up was made for you.
