Use this serum for the 1st time
I've been using this serum for about two weeks, but only once a week since my skin is pretty sensitive and I didn't want to irritate it. So far I haven't really noticed any difference. Maybe I just need to stick with it a bit longer and slowly work up to twice a week, hopefully that helps better.

Packaging flaw
I have been using Timeless products for a number of years. I have ordered the Vitamin C in bot the 20% and 10% formulas. I do like the products but have had a number of problems in the past with the bottles leaking around the edges when you push the pump. Very disappointing.

Bad smell..
The good: application is nice and it did not seem to irritate my skin. Shipping was quick, cost was good. The bad: the smell. When applying the serum it very much smells like hot dog water. I do not know who came up with that description but they were spot on. I will say that the smell dissipates rather quickly. My big problem is that it left a metallic smell (almost like blood) on my hands and face all day long until I washed it off. I could not handle smelling it all day. Unfortunately, I do not think I can continue to use this product.

My favorite
Love love love this serum. It makes my skin feel smooth and soft. Has a woody smell. The price, especially on sale, is in my limited budget. Thanks for making an affordable product in these expensive times.

Wow! Better than the much more expensive brand.
Honestly I'm shocked and happy about how my skin looks from the first try. Skin is glowing and age spots are much less visible. I honestly can't believe it. And because it's 4 ounces I have enough to use it on my arms and hands, decolletage. It's very gentle and my age spots are so faded after only a few days. I used to use a much more expensive brand but it got too expensive and the results weren't as good. Thank you!

Timeless Vitamin C + E Ferulic Acid is great
I like that Timeless is a light weight formula that is easily absorbed. It is not sticky and layers well under my moisturizer and sunscreen.

Great so far
The only vitamin c serum I have found that doesn’t peel when I put my moisturizer on over it! I just neutrogena hydro boost water gel and they seem to be a good match. Love the formula, it down quickly and is not sticky. I’ve only had the vitamin c for a few days so I can’t speak to the effectiveness at this time.

No irritation
I tried the 20% version a few years ago and my skin couldn't handle it. I use Tretinoin every night. I use this 10% l-ascorbic acid during the day . I've had no irritation. My hope is that this will improve my collagen but also lighten my sun damage. I use the prescribed amount of sunscreen daily, rain or shine. I will re-review in six months with a progress report.

Great on sensitive skin
I have sensitive skin and struggled to find a good vitamin c + feurlic acid serum. I tried a few and I reacted badly. I've been using this a few weeks and its wonderful!

So nice on sensitive skin
This is the only vitamin c serum I've ever been able to use. It doesn't hurt. It goes on so nicely. It's perfect. I wish I found it sooner. I have tried to many vitamin c serums and had to stop using every single one.

Perfect Skinceuticals dupe!
Really enjoying this serum. Feels, smells and applies just like the skinceuticals one. I especially love the glass pump. The serum is definitely fresh. Will def be using as my go-to AM serum.

Incredible Performance
I absolutely love this product. This vitamin C is packed with incredible ingredients, I am so thankful there is a product at this price point that packs such a punch and has such efficacy. My skin radiates and glows. I have been using this vitamin C product now for about a year and my skin has never looked better. I love the natural glow it gives me - this picture is not the best but it is natural, after my early morning weekend cleanse and application. Simply glowing.

Love at first drop!
I didn't realize just how dry my face and neck had become until I started using this serum. After only a few days of using the 10% Vitamin C + E Ferulic Acid Serum, my skin felt noticeably smoother and silkier. It absorbs well, layers nicely under my moisturizer, and has really helped improve the overall texture of my skin. My face and neck feel more hydrated, soft, and refreshed, and my skin looks healthier already. I'm very impressed with the results so far and look forward to seeing continued improvements with regular use.
