Also known as: Elravie Re2O, ECM skin booster, hADM booster
Re2O is made by L&C Bio from human acellular dermal matrix (hADM) processed into micro-particles, supplementing ECM components such as collagen and elastin directly in the dermis. Most boosters signal the skin to make collagen; Re2O supplies the scaffold itself. A finer version, Re2O Fine, is used for the under-eye area and neck.

Overview
What is Re2O (ECM booster)?
The dermis is held together by the extracellular matrix — collagen, elastin and hyaluronic acid. When this framework thins, skin loses density and fine lines appear.
Because Re2O is derived from human tissue, we explain this clearly before you decide. It is often chosen by people whose skin hasn’t responded much to other boosters.
How it works
How it works
Collagen, elastin and related components added directly.
The matrix is gradually replaced by your own tissue.
Standard for the face; Re2O Fine for the under-eye and neck.

Doctor’s note
Re2O works differently from other boosters. It isn’t for everyone; it’s for skin that has become thin.
