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.

Absolutely in love with this serum. Not greasy, smells is minimal and I have seen a drastic change in my skin. I keep it in the refrigerator and use it in the morning and sunscreen afterwards. I use prescription retinol at night and the combo of these two powerful ingredients are quick and noticeable. If anyone’s skin can tolerate this high percentage of pure vitamin C, I would say no other vitamin C serum can compete with this one. Will buy again!

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.

Some things to note. --This may smell 'fishy' or otherwise not pleasant - that is normal. Most all vitamin c serums will smell funny. They shouldn't smell 'rancid' or like old oil, but the fishy smell is normal. That's why some brands will put fragrances - to mask the off-scent of vitamin c. --If you don't use vitamin c within a few months, it may start to oxidize - if your vitamin c is turning darker, then it may be oxidizing and that isn't going to be as effective. I keep mine in the refrigerator just to be sure, though I use it every morning, so it empties quickly. --Everyone's skin is different, but this is a stronger vitamin c so you may have irritation, or slight stinging when using. You'll have to gauge whether this is temporary and okay or if this is too strong a formula for you. There are other vitamin c serums that aren't as strong. I will say that Cosrx has a vitamin c serum that's about this strength and I don't get the stingy feeling from it as much as I do this TirTir - though the stingy feeling doesn't last long. --This is slightly oily but so are other vitamin c serums that I like so I am used to this. Cosrx, Gangnam Glow, those are slightly oily too, and those also have the fishy odor (though Gangnam Glow uses essential oils to mask it- Cosrx does not). --If you have rosacea prone skin like I do, the way to use this may be important. I use my vitamin c after cleansing and toning but I wait between those steps as I want my face dry and the toner(s) to be absorbed. So I cleanse, tone, and then go get my coffee, take the dog out, whatever, and then apply my vitamin c. I then let that absorb while I do something else in my morning routine - maybe 15 minutes at least, and then go ahead with the rest of my skincare. This works for me. I do not like their dropper. It doesn't pick up the serum very well - and that goes for their milky toner too. Don't know what's up with their droppers. Would I order this vitamin c again? I would think about it -but particularly if this was on sale again, I would.

Right off the bat, this stuff is potent! If you are new to vit c then I would use this one to two times a week and build up. I usually use it in the am after a milky toner. It has the feel of baby oil (best way to describe it), but it doesn’t make me feel oily and looks great under make up. It is recommended to put it in the fridge to help prevent oxidation and so far so good. I don’t notice any sort of weird smell from it and am overall very happy with this product. This is the second TirTir product I’ve tried. Their milky toner is also phenomenal.

I just received this serum recently, and while I can’t really say how effective it is just yet, there are a couple of things that stand out — not necessarily in a good way. First off, the smell isn’t great. There’s a slightly fishy scent that I really don’t care for. It lingers for the day, which makes using it less enjoyable and I find myself constantly noticing it. It also leaves a noticeable orange tint on my skin after application. I’m not sure if that’s part of the formula or if it’s supposed to fade quickly (it doesn’t for me), but it’s enough that I was a little shocked the first time I noticed it. I will probably switch to using it at night and hope it does not stain my bedding. Also it’s semi tacky after application. Once I followed up with my moisturizer I noticed it was not as bad, but towards the end of the day my forehead was pilling. This may have been due to my specific combination of products, however it’s never happened with prior C products in the same routine. What surprised me most is that I actually use and really like their enzyme wash and one of their other serums, so I expected this one to be just as good. Unfortunately, it’s not working for me so far — but I’ll give it a bit more time before making a final decision.

I love this , I started using 2weeks ago and I am seeing a big difference skinny looks firmer and smoother, more hydrated. Wrinkles are less visible. Skin is looking clearer. I have some pigmentation ans starting to lighten up. Very little goes a long way. I usually use 1 to 2 drops and that's it. I'm definitely continue using. My fave and new vitamin c serum.
