Kosas – Cashback, Rebates & Rewards

Like many others, my face and neck broke out in a severe, itchy rash from using the 'Revealer Skin-Improving Foundation SPF 25'. If you go to the Kosas website and read the 1 star reviews you'll see at least 176 other customers had the same issue as me. I spent 4 months with this problem coming and going, not knowing it was the foundation. I had repeat DR appointments, blood tests, with no clear reason to why it was happening. Kosas claim "We take this very seriously as performed safety testing with a 3rd party lab" but provide no evidence of the claims and no supporting information on when the tests are run. They have since ghosted me despite telling me they had escalated my case with senior management LOL. The foundation only started giving me this reaction 1 year into use (it was still in date for another 6 months). They clearly are not testing it during the products lifespan. Negligent company selling dangerous products. They refuse to confront the fact their products are causing genuine harm.

Unfortunately the lowest rating I could give it was 1 star. I purchased the brow/lash serum after reading about the great ingredients. I started using it on my lashes as directed, every night for 10 days. After 10 days I noticed my eyelashes were getting shorter than they were before using this product! I sent several emails, calling was useless, relating this and still have not received a reply. Instead, Kosas sends me emails touting different products.

I had a few questions and issues with my order, and the customer service replied with helpful information and solutions within 48 hours on business days. Very satisfied with the service I received, I would definitely recommend this website

The mascara is absolutely dreadful. It is labelled ‘Long wear’ but is really not even functioning as ordinary mascara. It smeared all down my face within an hour- it shouldn’t be being sold. I really think it ought to be recalled. The company had no interest whatsoever in helping me with my issue- which I truly believe is a valid one. I will never use them or Naturisimo again and I would just warn others about this as they are charging fairly high prices.

I have always had a great experience ordering from Kosas. When I didn't like an item one time, they gave me an immediate refund and I was told to keep the item anyway.
