Skin Care20% Vitamin C Plus E Ferulic Acid Serum, 1 Fl Oz (Pack of 1)

Favorite Vit C serum, even if it's liquidity and smells a bit odd. I can definitely notice when I run out - my skin is more luminous and glowy when I use it. And definitely great value for the money compared to other options. Also like the bottle design for longevity. I haven't experienced any sensitivity, even when combined with other actives.

My friend who is all about Korean skin care made me a list of products to buy to fix my face and this was one of them. I love this stuff but there's no way I can use the whole thing before it turns yellow. I wish there were smaller bottles at a lesser price so I could feel less wasteful. Now that it's yellow I'm going to smear it on my body and if it helps yay if not oh well. Idk if I'll buy again bc there's other things I can easily replace it with that doesn't go bad in a month or 2. It was stored in the dark to get maximum life out of it.

I have tried many Vit C serums, but I have read many times to make sure it also has Ferulic Acid (check) and ideally has a pump dispenser (check) versus the screw cap and dropper, which is what most include. Vit C supposedly degrades quicker when exposed to oxygen/air (you can Google that, it did not come from this Timeless serum manufacturer, although you should take caution with everything you read, regardless.)Can I tell you it works for sure? No. I layer a 30 SPF physical suncreen (I like Eucerin) on top of this 99.9% of the time. My skin is soft and clear and I have not had any negative reactions to this product.

I purchased this after being influenced by a group of ladies I follow. It is affordable and easy to apply and has left my skin feeling refreshed. I keep it refrigerated as recommended and the coolness on my skin in the evening after a shower is great. I haven’t noticed any big differences in my skin and the consistency is a little runny making it more difficult to apply. I also do not like the smell, but otherwise I like the serum.

This is THE miracle hotdog juice that works right away. It’s very liquidy and concentrated (if it stinks then you know it’s the good stuff) so be sure to not waste any precious liquid gold!!!!! I keep mine in the fridge to stay icy cold (supposedly it lasts longer) I’m 30 years old and I swear it already gave me the glow and tightness I had in my 20’s… this is a product I will forever keep buying!!!

This is my absolute favorite skincare product. And it is completely ruined by this packaging! The charm of this product when it was in the old style dropper packaging was that you could easily decant into smaller bottles and store in your fridge (very advantageous because this product oxidizes and goes bad so quickly). Also, in the old dropper packaging, you could always visibly confirm that the product was still “good” by checking the color by looking for any yellow color in the dropper (which would indicate the product had “gone bad”). However, the new packaging constantly leaks… which means that there is plenty of oxygen getting in to the product and ruining it. And There is no way to pour out some product to use now and store the rest in the fridge because the lid is not easily removable. And finally, there is no way to look at the color of the product. I had my suspicions that my product was oxidized by the time I was halfway through the bottle… I finally took the time to tediously pump, pump, pump the product out into a bottle. It was yellow!!! I had been using “expired” product for who knows how long.It’s such a pity because i truly respect Timeless for the practical, science based, no fuss approach they usually subscribe to. It is so hard to find vit c at the correct pH, and at such a high concentration. I’m going to have to switch to the slightly less concentrated serum from Maelove. Even though I use this serum everyday, two times a day, I just can use it quickly enough before it oxidizes—and THAT is when it is actually in air right packaging, not in this leaky pump!!! Point is, even though L-A Acid is a wonderful, powerful ingredient, You have to store vit c in fridge, in air tight packaging ! So disappointed !

I bought this because of a couple YouTube dermatologists recommended it. I had first tried a k beauty c serum and gave it away. I didn’t like how thick it was. The Timeless C is very watery and sinks right into my skin so I can put my other serums on right after. After a couple weeks I didn’t think it was doing anything, but I kept applying every morning. It’s been 3 months now and there has been a big improvement in the evenness in my pigmentation. My skin has more of a glow to it that it hasn’t had for a long time. For reference I just turned 47, and between this in the morning and adapalene at night my skin looks better than it did 10 years ago!

These are getting so expensive but I can't stop buying it bcuz it is soooo good. It brightens me skin and makes it radiance with just a few uses.bes part it has an airless pump which is best for a vitamin c so it remains potent. Worth the money!
