Introduction
Founded in 2015 by Iranian-American founder Sheena Zadeh, Kosas US has quickly become one of the most recognized names in the modern beauty industry. Known for makeup that doubles as skincare, the brand has earned a cult following thanks to its powerful yet gentle formulas. What began as a solution to Sheena’s personal acne struggles has grown into a global brand celebrated for products that look good, feel good, and actively improve skin health.
Kosas offers a fresh take on cosmetics: playful, vibrant, and effective. At the same time, it challenges the notion that makeup has to damage skin or forgo ingredients to create style.

Customer Reviews

Customers consistently rave about the Revealer Concealer, calling it one of the best brightening concealers on the market. Many say it blends easily, offers natural coverage, and also acts as a skincare product with visible benefits over time. The Wet Lip Oil Gloss is another fan favorite, praised for its moisturizing formula and high-shine, non-sticky finish.

Constructive Feedback
However, some customers have noted that Kosas products can deteriorate quickly. Some have reported strange odors, texture changes, or visible separation within a few months of opening. This is often attributed to the brand’s gentler preservation methods.
Others say that certain products, such as foundation or powder, may not work well on very oily or dry skin. Many users love Kosas, but some find the price too high for the amount of product, especially when it spoils quickly.
