1.Mainly used as a skin conditioner, inhibit angiotensin converting enzyme, enhance ocular lymphatic circulation, and promote water drainage.
2.It has obvious effect on removing dark circles, eye edema and wrinkles.
3.It is suitable for all kinds of eye care and eye bag removal formulas. It is recommended to be added at the stage of cosmetic production.
4.It is an effective angiotensin-converting enzyme (ACE) inhibitor; by inhibiting the activity of AEC, it reduces the constriction of blood vessels around the eyes and promotes blood circulation to remove dark circles.
1.Dipeptide-2 helps reduce puffiness and bags under the eyes. Puffy eyes are due to fluid build-up caused by poor drainage, fragile capillaries, and loss of elasticity. Fluid leaks into surrounding tissues and produces "bags".
2.Targets all three conditions by improving drainage, reducing capillary fragility, and reducing irritation and skin slackening while increasing skin firmness and elasticity.
