TIRTIR Pure Vitamin C 24% Face Serum – Dark Spot Remover for Sensitive Skin with Collagen Anti Aging Even out Skin Tone Non irritation tested, Wrkinkles, Korean Mild Vita C Facial Serum 1.01 Fl Oz

I must say that this product is impressive; it delivers great results. However, the scent could use some improvement ( fishy). While it's an unusual smell, the quality makes it worth it.

This is my first time using a vitamin C+ serum. I have been switching up my skincare and got turned on to K-Beauty skincare through Miss Darcei and the Tir Tir Mask Fit Red Cushion Foundation. I have been using this for about three weeks, and I am noticing a difference. I have some acne hyper-pigmentation and general pigmentation dark areas that I have noticed are less visible. It is even getting rid of my glasses marks on the bridge of my nose! I'm also noticing that some of my fine lines are less noticeable as well.Here's a few things you should know:1.) It is an oil-based serum. I was a bit nervous about that because I have combination/oily skin, but so far I have not experienced any breakouts or clogged pores. I use a dropper sized amount on my face and my neck, and smooth it into my skin.2.) The directions I have found have said to use this after toner. I use the Tir Tir Milk Toner Light. I clean my face with the powdered Tir Tir enzyme face wash, dry my face, apply the toner, and let that sink in before I apply this serum.3.) After I apply this serum, I let it soak in before I use the Tir Tir SOS serum as my moisturizer. I let that sink in, and then I apply sunscreen. I have not tried this under makeup yet, so I don't know how well they play together as an oily skin girl.I have not tried this with any other moisturizer, so I'm not sure how well this will play with other non-Tir Tir products.ADDITIONAL POINTS:a.) Do a patch test before you commit to applying this all over your face. I applied some inside the crook of my elbow and a little on my jawbone/neck area and waited 24 hours to see if I had a reaction. When there was none, I started using it.b.) This serum is strong, so use it every other day or twice a week until your skin gets used to it. I'm now able to use this five days a week, and I'm working up to seven.c.) VERY IMPORTANT! THIS HAS TO BE REFRIGERATED! I think the reason why people have had problems with it smelling and turning brown is because they're not refrigerating this serum after use. Don't store this in a hot place like a bathroom where you take your showers and hot baths. Use it and refrigerate it ASAP - this has to be kept in a cool, dry, and dark place. I have not had any issues of it smelling bad out of the bottle or on my face.d.) ALSO VERY IMPORTANT! Once you break the seal on this bottle, be sure to use this up in TWO MONTHS or it will turn on you. Oxidation turns this serum brown, so keep it sealed and refrigerated after use.So far I am very pleased with this serum and have made it a part of my daily beauty routine.

As a dedicated Korean skincare junkie, I was really excited to try the TIRTIR PURE VITAMIN C 24% SERUM based on all the hype and rave reviews. Unfortunately, this product completely let me down, and I’m sad to say I won’t be using it again.First of all, the smell is absolutely horrific. I’ve used plenty of Vitamin C serums, and while some may have a slight odor, this one literally smells like cat food. I tried to ignore it at first, but after applying it to my face, the scent lingered for all night, making it almost unbearable. It completely threw me off every time I used it, and I found myself almost unable to continue with my routine because of it. My daughter also noticed the smell and at that point I was done!In addition to the terrible smell, I didn’t notice any remarkable results after using it consistently for a few weeks. The serum felt slightly sticky, and while my skin didn’t have any negative reactions, I didn’t see any significant improvements in brightness or texture, which is the main reason I opted for a higher concentration Vitamin C product in the first place.I understand that skincare is very personal, and some people may have different experiences with this product, but for me, the smell was a total dealbreaker. When you spend this much on a serum, you expect both effectiveness and a pleasant experience. Unfortunately, this one missed the mark on both fronts.I really wanted to love it, but I can’t recommend this to anyone who values a good skincare experience, both in terms of performance and scent. There are far better Vitamin C serums out there, and I’ll be looking for another one to add to my routine.

It works! I wa looking for an OIL BASED vit c serum as I ran out of my last one thst was price like 40$ bc i have dry sensitive skin inlove oil based ones. Saw this and like their foundation and was on sale so gave it a go. This has to be the MOST POTENT vit c serum I've ever used and I've used at least 10. It is oil based so if that's not ur jam look elsewhere and it is potent so it does burn or itch my sensitive skin it I use it after exfoliating but boy does it work! Results in less hyperpigmentation and redness in only a few nightly uses! Will try to use it nightly and see how it improvements my skin! It does have a kind of weird smell but it's faint so idc and I use it nightly anyways. I like that it's not perfumed. Would repurchase. Potent and works. One less star for smell and irritation if my skin has been exfoliated.

I absolutely love their products & my skin does too. I’m a believer that not ever great products is great for everyone but, this is 100% for me! I would highly recommend trying this & seeing if it’s right for you!

Not sure if i saw results, no irritation. It has a weird fishy smell after drying down… maybe I got a defective product

I LOVE this serum. It feels so nice & you only need a little bit but I can’t use it :/ I used it once and it broke me out terribly & I never break out. So sad!

Amazing ! Gives you that glow and mine hadno odor.
