Product Overview
MBR Tissue Activator Serum is the peptide serum at the heart of the BioChange routine. Applied morning and evening beneath cream, it works on the look of density and elasticity, softening shadowed areas and helping contours read more defined.
The official formula highlights Trylagen™, Hyanify™ (HyaMar) and Ergothioneine (Thiotaine) EGT. Together, these components support the serum’s role in the routine while helping the treated area look and feel well cared for.
Recommended For
Recommended for skin that has started to look flatter and less resilient, particularly around the nasolabial area, the jawline and under the eyes. Follow the official frequency and precautions, particularly if skin is reactive.
Texture and Experience
A clear, concentrated gel-serum that spreads easily, sinks in without tack and layers cleanly beneath cream.
Key Ingredients
- Trylagen™: Triple-acting peptide and amino acid complex that supports the skin’s own firmness across its full cycle, for a better-quality look.
- Hyanify™ (HyaMar): Marine extract that supports the skin’s own hyaluronic acid, for more volume, density and elasticity in the look of the skin, especially around the nasolabial folds.
- Ergothioneine (Thiotaine) EGT: A multi-functional amino acid used in anti-ageing preparations and well tolerated by most skin.

Frequently Asked Questions
Where does it belong in the routine?
Morning and evening on prepared skin, after cleansing and before your cream. Massage it in gently and let it settle.
How does it differ from MBR ContinueLine Cell & Tissue Activator?
Both are density-focused serums. This one sits in the BioChange routine and leads with the Trylagen™ peptide complex; the ContinueLine version is built around Hyalufix™ and a soothing herbal complex.
Which size should I choose?
The 30 ml bottle suits a first course or travel; the 50 ml is the everyday size for continuous use.
Can I use it under SPF and make-up?
Yes. It absorbs quickly and leaves no film, so sun protection and make-up go on without trouble.
Is it enough on its own?
It is a treatment step, not a moisturiser. Always follow with a cream so the serum is sealed in.
