The Science

The unique nano gold technology that is present in all Endor Technologies skincare products boosts the natural revitalisation of skin at the cellular level. The nano gold technology is made by uniting tiny fragments of hyaluronic acid with tiny particles of gold that are so small they are able to enter the skin dermis and activate multiple cell receptors, stimulating the natural production of hyaluronic acid, collagen and elastin; which over time results in smoother, firmer, healthier skin reducing cellulite and signs of aging.

Articles & Studies


In Use Efficacy of Serum and Cream Containing HA-Conjugated Gold Nanocomplexes to Increase the Synthesis of the Epidermal Extracellular Matrix and Improve the Skin Condition.

In use double blind, randomized, placebocontrolled efficacy test of a cream to reduce the cellulite effects and increase the skin antioxidants.

In use double blind, randomized, placebocontrolled efficacy test of a serum with gold nanocomplexes combined with radiofrequency to reduce the cellulite effects.

In use, randomized, active-controlled efficacy test of a post-fractional laser cream with gold nanocomplexes to improve wound healing and reduce adverse effects.
