마이 시그니처 C 소스

Thank you so much 0.8L for sending me the My Signature CSource vitamin C20% and thank you TIA’M for letting me try this excellent product. This is my second vitamin C serum trying, the first serum is from KLAIRS and now I had the opportunity to try TIA’M’s CSource serum. After using this serum for 8 days I see my skin brighter and soft. I was worried that my skin will feel a big difference after changing from KLAIRS to CSource but it did not irritated my skin. The texture of this serum is between a light oil to a light gel that melts in seconds. I don’t like heaving emulsions or creams on my face because I have combination to sensitive skin but with this serum I didn’t feel any burning or sticky feeling. The smell is citrus but it goes away after a few seconds, if you are extremely sensitive to fragrances try a sample size before you buy the regular size because even if the smell is light and goes away fast some people may not like the smell. I use this serum during my night routine and I love how bright my skin looks in the morning, hopefully it keeps brightening my skin. The price is not bad, the average price is $25 dollars but you can use it between 4 to 6 months if you live in a hot area keep it in a cool place because it may change color. This serum claims that it will regenerate, brightens and makes the skin looks healthy, I do support this claims because this serum does all these. I recommend this serum to combination and uneven tone skin. I will keep using it until I see extra changes on my skin. #c20serum #tiam #csource #ostc20 #vitaminc #08L

I was really trying to test it out for as long as I could to see if I could tell a difference in my face and time just flew by. I literally had it for about a week and other than my face feels soft after, I can't really say that it brightened up my face or helped reduced my pores as it claims to do. I think I'd probably have to use it for about a month or longer to see it if helps erase or lighten any blemishes on my face. Which TBH is reasonable, nothing is over night! The citrus smell isn't as over powering as I thought it be, it's super light and honestly after awhile it's so settle I don't even notice it anymore. But if you don't like citrus aromas then I'd skip this product. The only thing negative I have to say was that it took awhile for it to soak into my skin so at first I felt a little sticky and didn't want to touch anything, so I'd refrain from laying down right after applying or changing clothes. Other than that I haven't had any issues and definitely recommend giving it a try.

This product is perfect for my skin..Im in in my early 30's now and its time to start using products that nourish and protect.This vitamin c serum is wonderful and i love the fact that it came with a dropper for ease of use.And the packaging is so sleek and pretty.My Signature Csourse is now a part of my skincare regime thanks to Tiam and 08L. For my reveiwing opportunity. #c20serum #tiam #csource #ostc20 #vitaminc #08L

I used this on my hands, legs and arms as I mixed it with my body lotion. It worked pretty well together. It moisturized my body and kept me away from ash. I was nervous to use it on my face so I didn't even bother. My skin is highly sensitive so this did do ok. I wouldn't recommend to use it on its own.

I was very excited to try the Tiam My Signature C Source Serum because it's often compared to the Timeless and NuFountain 20% LAA Vitamin C Serums and I was wondering how they compared. While the other two have a viscosity similar to that of water, the Tiam serum has a more traditional serum-like consistency, comparable to a very runny gel. It makes application of the serum easier since the serum doesn't run all over the place when you're applying. The other two didn't have much of a scent, but the Tiam is fragranced to smell like oranges. I don't particularly mind the scent, and it smells nice actually, but those who have sensitive skin or avoid fragrance wouldn't enjoy this aspect. I haven't been using the serum long enough to see the PIH lightening that will occur after a couple of weeks, but the product hasn't broken me out and isn't unreasonably drying so I will continue using it.

One more Vit C in my routine.. With repeated use of any good branded Vitamin C I have noticed definite improvements in my acne scarring and with my undereye circles. As a note, this (along with all Vitamin C serums) are not a quick fix formula. It takes repeated, consistent use to get results.

Got to try this out thanks to @0.8l_usa! Fits perfectly into my nightly routine. Super fresh, and no oily feeling. Smells very similar to Oranges 🍊 overall, two thumbs up! #08liter #productreview #reviews #beauty #skinregimen #oranges #smellslikeabowloffruit #c20serum #tiam #csource #ostc20 #vitaminc #08L

Here's a first impression on the Tia'm C Source! 🤓 This comes with a dropper dispenser. It is 20% vitamin C, as you can see on the ingredient list. I like how clear they are about that! The bottle is glass and tinted to protect the vitamin C. They recommended refrigerating this as well. Last night I used a dropper-full after my toner, waited 15 mins, and used a cream on top. This morning my face felt really smooth and looked even & calm. This stuff smells kind of like those High-C packets that you drink when you want a boost of Vitamin C. 😆It's viscous by not sticky, and only feels a little tacky after drying down on my face. Overall I liked it, and I'll continue to use it twice a week! (Also remember to use sunscreen!!) ☀️I got this from @0.8l_usa to review for free! ----------------------------- #skincare #skincarereview #skincareblogger #instabeauty #instablogger #instareview #kbeauty #kbeautyaddict #kbeautylover #kbeautyblogger #kbeautyskincare #asianbeauty #rasianbeauty #abcommunity #abskincare #bblogger #beautyblogger #asianbeautyproducts #asianbeautyblogger #asianbeautyskincare #08liter #review

i was not epecting to love this product as much as i do, it smells really nice and left my face feeling clean, and ever since i started using is i have not had many breakouts. it is not part of my skin care routine.

Here is my honest review in return for a free bottle of My Signature C Source. YOU, yes you, youneed this. Buy it. Try it. Love it. I found this sample opportunity as an alternative to a more expensive solution with the same ingredients. I've incorporated it into my daily skincare routine which includes washing my face with a clarisonic and moisturizing in the morning and then washing and treating again at night. I use this serum after washing but before moisturizing five mornings a week. In one week the difference in my skin is incredible. I have more luminous, even-toned skin and better hydration throughout the day. A co-worker even commented that I look "younger and well rested". Maybe I am more relaxed? Who knows. I certainly didn't have plastic surgery! Either way, this is a quality product at a good price for what it will do for you. I strongly recommend anyone try it, even men! #c20serum #tiam #csource #ostc20 #vitaminC #08L

I had an opportunity to try out the much talked about TIA'M My Signature C Source Serum via 0.8L and I am absolutely in love with it. Over the period of two weeks there has been a considerable change in my skin and things look even better going forward. The serum is pure Vitamin C that helps regenerate, brighten and firm your skin. It has also really helped lighten my acne scars and I am sticking to it for life!

This Vitamin C serum I've been incorporating into my morning routines and also storing it in my fridge to keep it fresh. It has a dropper applicator, and I find a bit more viscous than other vitamin c serums I've tried, although it spreads really nicely and only leaves a slight tacky feeling to the skin that goes away once I apply moisturizer. I find it nicely hydrates the skin, while also providing some brightening effects. I think this works just as well as some other more expensive Vitamin C serums out there, and I'd definitely purchase in the future.

This is a very thick and moisturizing serum. It doesnt feel like you have anything on your face, and it didn't feel greasy allthough my skin was quite shiney looking. The product comes in a very nice glass bottle with a glass dropper. The quality feels amazing. Following the directions, I mixed a few drops in with my moisturizer on the first day to make sure that my skin wouldn't have a reaction to the serum. I did find that it left my skin feeling sticky to the touch, but after a while, the moisturizer seemed to help diminish that effect. I ended up using the product only at night, because vitamin C does diminish in the sunlight so using the serum at night gives it more of a chance to work. Why buy something and use it just to waste it, right? As for the claims, I did notice that my acne was getting better after a few days. This isn't very fast acting but it does work and I think it would be good for someone with more mild acne and/or acne that you have trouble getting rid of that just seems to always stay. Because of the oil level, I would reccomend this for someone with more dry skin, but it still worked fine on my more combination/oily skin type. The only gripes that I have with this product, is the availability. I could not find an actual company website for the product. Although I could find the product for sale, the prices were so different in range, that it makes you question if the significantly cheaper version is still good product or a scam. I found the product listed on some asian sites and on ebay. To any buyers, I will just warn you to do your research on where you are buying from and make sure that it is a crediable source. But the product itself truly is quite nice. I would reccommend this to people to try, especially if you find one of those $8-$16 bottles. It's a good size, you don't need to use much, so it lasts a long time and I love that. In the english instructions that I recieved, it didn't say how often to use this product but I incorporated it into my nightly routine and used it everynight. Thank you to TIA'M for letting me try this prodcut. It was a wonderful oportunity.

I've been using it a little over a week and I wanted to give first impressions. This is a strong Vitamin C! 20% on the label and it does have a nice tingle when it first goes on. It's sticky on and my face feels tight after using it, BUT I haven't had any issues with pilling or issues applying makeup over. The tight feeling goes away once I moisturize. It's a clear formula which is great because sometimes companies add orange coloring to hide the natural process of vitamin C oxidation, but clear formulas you can see when it's gone bad. As for results, I do think it's cleaning up some acne scars but only time will tell how effectively. So far so good though so I definitely will continue to use and give another update when it's an empty.

I LOVE the C-Source vitamin C serum. The product size is huge, it smells really great, and it works really well. The serum absorbs into the skin and doesn't leave it oily. I would definitely recommend this product!

This serums from @tiam_korea is amazing! I'm about to run out of vitamin C serum and it came at the right time! . Straight away, I detected a slight orange-y scent (which I honestly expect from a good vitamin C serum 😂). Unlike my last vit C serum, I'm keeping this in my fridge. It feels really nice when it's cold, so I might start putting more serums in there! . It tingles a bit, when first applied, so it is a potent serum. And it straight up STRINGS when applied to broken or irritated skin, or acne. . Overall, I'm seeing amazing results with this serum! I can't wait til I finish my current bottle so I can start using this one full time!

I received this product for free from @0.8l_usa and @tiam . I've been using [TIA'M]My Signature C Source serum for about 1 week now and I really like it. I keep mine in the fridge because I did some research and learned it will keep the serum fresher longer and prevent discoloration which is common with vitamin c heavy products. The serum is very runny but very absorbing. Pleasant citrus scent. And my picky skin has been enjoying the product. I mix a few drops in woth my other serums and worl everything into my face gently I. Upward motions.  Overall: 4/5 stars thumbs up!!  DESCRIPTION and how to use from company below~~  [Description]My Signature C Source delivers a multitude of complexion benefits for beautifully healthy skin. Pure Vitamin C fine, brighten, balance, and tone skin for a radiant appearance. [How to use]After cleansing and toning, apply 2-3 drops gently all over face everyday night as Serum. Recommend to use at night. Applying sunblock is essentially needed during daytime. Slight stimulus may be experienced at the first time to use Vitamin C serum. Mixing with several drops of serum and toner makes your skin refresh without sticky feeling. After absorption, follow with appropriate lotion and cream.

#TiamKorea My Signature CSource is one of those OG kbeauty famous product that I never tried before. I long debated buying it back when it was named OST C20 (still not sure why they would waste the name recognition by changing it..) but I worried about how it would fare during long transit times and the complaints concerning short shelf life because the product oxidized. So when #08L put this product up, I jumped at the chance to finally try it out. As usual, 08L's looming review deadline mandates that this has to be more of a first impressions type review. 🔸Texture: Thicker than I expected, more viscous serum type than watery. 🔸Scent: Very light citrusy (because of sweet orange oil added), no hot dog water scent like the ones that include ferulic acid. 🔸Feel: Skin tingled a bit (manageable though, not painful) the first time I used but didn't feel anything on subsequent applications. 🔸Finish: Slightly tacky in feeling but nothing too bothersome and I was able to apply lotion on top without any issues. 🔸Effect: At the time of this writing, I've used this for only 6 days total, so can't make any definitive conclusions about the long term effects. The PIH in my chin seems slightly lighter but again, it's still early yet. I'll continue to use this and will update if I see any impressive results or if my bottle oxidizes within an inordinately short amount of time. Right now I've been keeping my bottle in the fridge to be on the safe side and it's a light champagne color.

Vitamin C is always a great ingredient to have and concentrated serums are the bes tin my opinion. But due to the nature of Ascorbic Acid, it is easily compromised, which can actually lead to skin damage!!! If your Vitamin C serum looks orangish in color, immediatly stop using it! I have personally had experience with this and it was so sad to have to throw something out. One way to help preserve it is to keep it in a cool, dark place. Preferably not the bathroom!!! Something that I really love about this serum is that it contains 0% water, which helps to keep it stable, and because it contains Rose Bud Extract as well as Camellia Sinensis Leaf Extract! So far I have experienced no irritation with this formulation. As a side note, you may have seen or tried this product as it has been re-named. It used to be called O.S.T. C20 - Original Pure Vitamin C20 Serum and is now made by TIA'M and is called My Signature C Source.

Received this fab My Signature C20 Source by Tia'm for Free from @0.8l_usa in exchange for my review. 🍊 Original Pure Vitamin C20 Serum; Simple skin care with only one vitamin C. Faster Vitamin C effects  with added peeling function. Combine 20% L-ascorbic acid with natural antioxidants to help prevent permature signs of aging. Protect, soften and moisturize your skin. Vitamin C Serums are my holy grails of All holy grails. I love how this serum is thicker and moisturizing. It barely has any scent & absorbs w/o being sticky. I love that it works well with other serums + moisturizers. I apply daily then apply my moisturizer.. Then apply Sunblock as if my life depends on it. My skin looks and feels so healthy & bright. I hope with long time use my dark patches on my cheeks will fade. I recommend everyone use a Vitamin C treatment in their skincare routine. #08literusa #08L #review #tiam #mysignature #c20 #serum #kbeauty #koreanbeauty #beautiejunkies #skincare #skincareaddicts #vitaminc #bbloggers #dermalove #dermatologist #esthetician #aesthetician #shopthetrend
