KNESKO is a gem-infused, high vibrational skincare brand founded by celebrity esthetician Lejla Cas. Each product is developed under Lejla’s creative direction alongside a team of board-certified dermatologists and cosmetic chemists. 

Origin Story

Lejla’s career in the beauty industry led her to the United States in 2007, where she worked in roles ranging from education to product development. While working with globally recognized brands, she also provided her intuitive skincare and makeup services to private clients.

In these hands-on-skin interactions, Lejla realized everyone sought something similar: intentional time to recharge and a skincare routine that was effective, luxurious, and healing. This inspired her to create KNESKO with her husband, Sean Nezhad, in 2012. 

An Industry & Celebrity Favorite

KNESKO has garnered enthusiastic attention from the beauty industry’s most discerning consumers, including estheticians, salon owners, and makeup artists who rely on the product lineup to create a lavish experience and remarkable results for their clientele. 

KNESKO’s gemstone serums, collagen masks, and facial tools are also used in treatment rooms in over 1000 5-star spas and high-end resorts, and are a staple for celebrities such as Halle Berry, Pamela Anderson, Nina Dobrev, and Ashley Graham among others.

“ At KNESKO, we work closely with a team of doctors to harness these incredible properties and create CUTTING-EDGE PRODUCTS THAT ARE AS EFFECTIVE AS THEY ARE OPULENT.

We celebrate precious gemstones and minerals not just for their beauty and healing properties, but for their ability to uniquely optimize our skincare formulations.

These ethically sourced gemstones and minerals—which include gold, diamonds, black pearl, and others—help amplify active ingredients by improving the delivery process, stabilizing ingredients, and making powerful actives more bioavailable. The result is highly effective, cutting-edge formulas that deliver visible results.
