I added this to my morning routine and my skin shines! I also got a nice peel adding it to my Retin A routine. So basically I do t have to use as much of my RetinA. After the peel my skin adjusted and I put it on my chest, hands to help with sun spots. Timeless is my favorite line and I'm a skincare junkie/snob....they are a trusted game changer. I just order 3 more items from Timeless because this Vitamin C is the best I've ever used. Price is wonderful and lets me spend more on their other products. Instead of buying a high end with extra ingredients that might work or might not. Timeless is high end to me. Forever customer now!!!
Update: This is a game changer in my skin. I still think this is the best Vitamin C serum. I've had it 30 days and it's starting to oxidize although it's kept in a dark cool place. When I order it again, I will make sure to separate it into bottles. I did read where the ferulic Acid in it will keep the Vitamin c stable longer even if its starting to turn yellow. The more yellow it gets the lower the percentage in the Vitamin C but it's still working. Now when it's starting to turn a dark yellow to brown obviously toss it. Hope this helps. My skin has a glow it's ever had before though. This stuff works!

My 3rd time purchasing, I enjoy this Vitamin C serum very much. I usually make my own but because I sometimes get busy and don't always feel like doing that, this is my second choice. I enjoy that it has Ferulic Acid in it and E in it especially. I also like the dark-tinted bottle and the dropper application, which seems to be standard. After I apply any Vitamin C serum, I apply quick penetrating dry tsubaki oil (C. Japonica, not to be confused with C. Sinesis) and then I feel like I have the basics on my face for the day. (Sunscreen or BB/CC creams to come afterward and your skin will stay in love with looking and performing its best on your beautiful face,)

Love this stuff and continue to purchase. This makes my skin look healthy and it clears up my breakouts over night!!! Ive tried everything to solve poor skin issues this is the first thing that has worked. I've tried other brands and had bad reactions, one dried out the skin under my eyes so bad that it felt and looked like sand paper. I've never experienced such healthy skin. I love makeup and wear it daily but this evened out my skin tone and no need to wear foundation unless I am on camera for work this is huge as I have spent thousands trying to find foundations to cover up issues now I don't have to hide. Everyone's skin is different but this has been life changing for mine.

I bought this serum because it offers a potent antioxidant (20% vitamin C+vitamin E) option for my aging skin. It boosts the effect of my sunscreen and leaves my skin looking freshened and hydrated. It has a longer shelf life than some of the other brands. I have used 2 other brands before Timeless. I prefer Timeless. I store my serum in its box in the refrigerator. The dropper is an efficient way to dispense it. The serum is more viscous than water making it easier to apply. It is odorless and does not leave an odor on my hands like another brand does. I have not tried the more expensive version of this serum. I like Timeless, so I am not interested in spending more money. I am glad to have this alternative.

I love using Vitamin C and E on my face - it is part of my morning and night time ritual. After washing my face I gently pat on Vitamin C, Hyaluronic Acid, and a moisturizer on my face. I like this product because of the high concentrations of product used and its shelf life (3 months versus 1 month of other brands).

This product is not greasy and doesn't have a "overly medicinal" smell. I like using Vitamin C because of increases skins collagen boosting abilities and evens out skin tone. This product also contains vitamin E, which enhances the antioxidant effects of vitamin C when they are co-applied to the skin, the Ferulic acid also enhances Vitamin C and E's antioxidant abilities. The hyalunronic acid content aids in hydration of the skin and holds in moisture. I have seen a noticeable difference after a couple of months. Prior to using this my skin was noticeably dry and discolored.

I purchase this brand and product every three months and highly recommend using it as part of your skin care regimen.
