Having had several skin booster sessions and still finding that the skin turns dull again before long is a more common complaint than you might expect. If hydration lifts for a moment while firmness and density stay exactly where they were, it may be the approach rather than the product that needs changing. This article looks at Re2O, an ECM skin booster built on the idea of replenishing the structural components of the skin itself.
What actually happens in aging skin
Collagen and elastin in the dermis decline gradually as the years pass. On the surface, that shows up in turn as reduced firmness, a rougher texture, and fine lines. Most skin boosters to date have approached the problem along one of two paths: applying fine micro-stimulation to prompt collagen synthesis, or filling in hydrating ingredients such as hyaluronic acid. Either way, the strategy comes down to waiting for the material to be rebuilt.
What makes Re2O different
Re2O injects extracellular matrix, or ECM, obtained from human allogeneic dermis. ECM carries the core components that make up the dermis, including collagen, elastin, and hyaluronic acid, with their original binding structure preserved. Filling in a structure that is already assembled, rather than waiting for new collagen to be produced, is where it parts ways with earlier skin boosters.
What the treatment aims to change
The treatment is directed at recovering firmness and skin density, refining texture, softening fine lines, and supplementing volume where the face has hollowed. Because the aim is a dermis that supports the skin on its own rather than a temporary, moisture-led change, it can be worth considering for skin past middle age that needs dermal recovery, or for those who were not satisfied with other skin boosters. The degree of response and how long it lasts vary from person to person.
Two injection methods: by hand and by cannula
At Skinique Clinic, the choice between hand injection and cannula is made through consultation, based on skin condition and the purpose of the treatment, because the strengths of the two methods differ. What follows is an example of a session carried out by hand injection, beginning with numbing cream left in place for a sufficient time.
Before injection, the genuine Re2O is unsealed and mixed in front of the person receiving the treatment. The step exists so that you can see which product is used and how it has been prepared before the session begins.
With the hand injection method, one vial is prepared as 6cc, divided across six syringes, and injected in fine increments area by area.
Discomfort and getting back to your day
Discomfort and bruising during injection differ from person to person and are hard to describe in a single way, but they generally pass at a level that does not greatly disrupt daily life. If anything concerns you, raise it with the medical team beforehand and they can explain how to prepare. Whether pairing it with a lifting treatment that supports collagen renewal, such as Thermage FLX, suits you is something you can discuss at the same time, and detailed costs are listed in the price guide.
Wrapping Up
Re2O is a skin booster that begins from the idea of replenishing the ECM that makes up the dermis directly, instead of waiting for new collagen to form. If loss of firmness and density is your concern, or if the results of other skin boosters left you wanting, it may be one option worth weighing.
