• Tea tree oil nanoemulsion containing adapalene gel demonstrated significantly greater reductions in total, inflammatory, and non-inflammatory acne lesions as well as acne severity index compared to adapalene marketed gel in 100 patients with acne vulgaris over 12 weeks.

  Journal of Ocular Pharmacology and Therapeutics, 2019

• Incorporating nanoemulsions into hydrogels with increasing Carbopol 934 proportions from 1% to 3% progressively decreased the percutaneous flux rates of terbinafine and citral, increased drug accumulation in the stratum corneum while decreasing it in the epidermis/dermis compared to nanoemulsions alone, and shifted delivery routes from skin appendages to intercellular paths.

  International Journal of Nanomedicine, 2016

• Topical liquiritin carbomer gel treatment restored skin barrier function, increased barrier proteins and antioxidant enzymes, and decreased inflammatory cytokines and oxidative stress in a mouse model of glucocorticoid-induced skin inflammation.
