Indications

Fine lines and wrinkles around the eyes, temples, and neck
Dull or sagging skin needing improved tone and texture
Thinning skin caused by collagen depletion
Uneven skin surface and enlarged pores

Active Ingredients
Polycaprolactone (PCL)
A biodegradable polymer that stimulates collagen production, improving skin firmness and elasticity over time.
Glutathione
A powerful antioxidant that brightens the skin and reduces pigmentation, promoting a clearer and more radiant complexion.
Glycerin
Provides deep hydration and maintains skin moisture balance, leaving the skin soft and smooth.
Mechanism of Action
Rejuner Black works by combining Polycaprolactone (PCL) and Glutathione to rejuvenate the skin from within through two synergistic processes:
Collagen Stimulation: Once injected, PCL forms a smooth, particle-free colloid that spreads evenly through the dermal layer. The PCL molecules gradually stimulate fibroblasts to produce new collagen, strengthening the skin’s structure and improving elasticity. This neocollagenesis process continues over several months, resulting in long-term lifting and wrinkle reduction.
Skin Brightening and Protection: Glutathione acts as an antioxidant, reducing melanin formation and protecting skin cells from oxidative stress. This brightens dull areas and helps even out overall skin tone.
Together, these actions lead to firmer, smoother, and more radiant skin, with visible rejuvenation that can last up to 24 months.

I used this product a few years ago and since it is a sale on meamo, I purchased the whole box again. I don’t want fillers and don’t really have tear troughs but do have crepey eyes with loss on temples. This was amazing via a cannula..u remember how tight my eyes were and along with a pn products this is going to be great. This is not volumising but it is pcl and correct placement will help to create a scaffold that prevents skin from getting loose. Cannula is the best method imo, quick and easy avoiding Tyndall effects too.
I bought for my undereyes, but I haven’t used it yet. The reviews I’ve seen and heard on this product are fantastic.
Fast shipment! Packaged well!
