Never shop on TikTok Stay Away from KOSAS

Never shop on TikTok! Always takes forever to deliver. As soon as you order they pretend they have shipped so any requests for cancellation is ignored.Kosas emailed me they would contact me about my request to cancel my order...they DID NOT! Instead they shipped it so that I will have to pay return shipping - hoping to deter returns I'm sure. Never again! I will review the actual items when I get them IF I decide not to return-depends on the shipping costs! They don't care what we think--they don't even look at the reviews! Stay away from KOSAS and TikTok!!!

Terrible customer service!

Love the lipstick. Hate customer service. Contacted them immediately after placing my online order to upgrade shipping as I realized it won’t arrive before I leave. No deal. Absolutely no flexibility, no help and no they can’t process it as a refund until it arrives, after I’ve left. Phone number appears to be disconnected. Never had this problem before. Never will buy again!

Hands down the worst custom service…

Hands down the worst custom service I've ever dealt with. Their policy right on there website says I can request cancellation within first hour after purchase. I received confirmation emial 40 minutes later, that they would be getting to me shortlyI finally got in touch when they opened, and because waiting for them to open exceeded an hour, they said there is nothing they can do. I will never shop here again

Negligent company selling dangerous products

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.

Thumbs down.

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.

Helpful and friendly customer service

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

Be careful before you order

horrible experience with customer support. They won’t reply to my emails. Only when I commented under an instagram post to please get back to me they reached out via DM to ask for my email. I gave it and guess what. Nothing. Still they won’t reply and help me. Be careful when you order because if you encounter an issue they won’t get back to you to reply.

The mascara is absolutely dreadful

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 bought the skin-improving foundation…

I bought the skin-improving foundation SPF 25 and it’s been ok so far, my skin doesn’t break out. It’s too oily for me though! And the smell isn’t pleasant! It’s not bad but for the price I’d expect it to be better!

Bought me out in hives

KOSAS BB BURST TINTED GEL CREAM 30ML.The day after I used this, my face became itchy and small bumps began appearing on the side of my face, both left and right. This was Friday 12 April. Saturday 13 April, woke up even worse. Hot to touch, taking antihistamine tablets. Today Monday 15th April, still the same, and now looking to seek a doctors appointment as I feel I need something stronger. Would not recommend this Kosas product.Having now done my research, I see that other people have had a similar experience.
