Best vitamin c serum
I’ve been using the Timeless Vitamin C Serum consistently for a few weeks now and I can honestly say it lives up to the hype. My skin looks brighter, more even-toned, and noticeably smoother. That dull, tired look I usually wake up with is gone. Now I get compliments on my skin without makeup. The texture is light and watery which I actually love. It absorbs quickly and layers beautifully under my moisturizer and sunscreen without pilling or feeling sticky. There’s a slight citrus scent from the vitamin C but it fades fast and hasn’t irritated my sensitive skin at all. What I really appreciate is the ingredient list. It contains 20% L-ascorbic acid, ferulic acid, and vitamin E, similar to some luxury serums but at a fraction of the price. It’s packaged in a UV-protected bottle to keep it fresh which shows the brand really thought it through. If you’re serious about fading dark spots, boosting radiance, or just improving overall skin texture, this serum is a game changer. Affordable, effective, and trustworthy. It’s now a permanent step in my morning routine.

My day time skin care staple
I have very sensitive skin and usually after one or two uses can tell if a product will work for me or not. I am so sensitive I cannot even use the Vitamin C serum from a brand that is well known for products for sensitive skin. I have not had a reaction to this product which is fantastic, as this is the first Vitamin C product I can tolerate. It is not sticky, no residue or overly shiny appearance. My face was smooth and it felt like I was not wearing anything at all. I have been able to layer this with another serum from another company for another concern and it worked well. The smell- I was warned that any good Vitamin C serum is going to smell like "hot dog water" by a dermatologist, and while I am not sure its quite that smell, it does have a slight odor, but its not offensive. No fragrance other than this natural product odor. It was clear and not oxidized which many have said. I have had nothing but good results already that I think this is going to be my go to Vitamin C from now on. I normally do not wear makeup, but I even received two compliments since wearing this ( without any makeup) at work which has never happened. It is already providing me positive results.

Good Product
Timeless vitamin C is great! I have only used a short while and my skin seems to be brighter! Good product.

Fine
Vitamin C is easily oxidized. It makes my skin looks yellow, although it protects the skin.

Perfection
Like many other reviewers, I discovered Timeless through Angie at Hot and Flashy on YouTube. I’ve always wanted to consistently use vitamin C, but SkinCeuticals is just too expensive and often arrives already oxidized. What immediately appealed to me with Timeless, beyond the formula itself, is the packaging. It’s the only vitamin C I know of that comes in an airless pump designed to prevent oxidation, and it’s so easy to use. The formula also includes an ingredient that helps make it less acidic, which is great for sensitive skin. I use the 10% version since the 20% feels too strong for me—likely because I also use Altrino, a tretinoin derivative, at night—and I’ve had no irritation. I’m able to apply it on my face, neck, chest, and hands without any issues. Kudos to Timeless for creating such an effective product at an excellent price.

Watery, smelly, and messy.
I've never used a serum that dispenses with a high-pressure splash, like water in its runny texture. The scent doesn't resemble typical vitamin C fragrances at all. When I first opened the bottle, I noticed dark brown dried residue, indicating some serum had leaked—probably because it’s primarily water rather than oil. I wouldn't recommend this product at all. It doesn’t feel pleasant, and I wouldn't want that on my face day or night, so I’m unsure of its effects on my skin tone. Overall, I don't consider it effective or of good quality.

Runny, Stinky, 10%
I read the wire*tter article (just like you, right?) that recommended this. It did not, however, prepare me for the smell or the out right “splashiness” of the texture. And while the article mentioned the 20% version, this is the 10%, despite the description. Pros: Not a thick, stinky oil (it’s a watery, stinky fluid!) Probably does a decent job absorbs pretty well Good packaging that doesn’t let air in Cons: The description says 20% but you will get 10%. The photos show 10%. Smells like Skin*ticals version, only lighter. Yuck. Runny like water, which is weird. Will I buy again? No. Am I returning this? No, I tossed the box. I’ll use it, but I’ll be happy for the day I run out.

Great, if your skin can tolerate it
If your skin can tolerate this product, it will leave you glowing. Excellent product but both potencies are too harsh for my skin (Paula’s choice niacinamide 20% treatment is the only quality vitamin C product that I’ve been able to tolerate daily)

Excellent quality. My skin loves it. I use it with a researched skin routine (AI) and apply in certain layers of different products. I also bought their Timeless Coenzyme Q 10 serum. Mature skin with a bit of spots not a lot of wrinkles for 77 because I always took care of my skin.

Has an organic orange peel smell. I usually prefer non-fragrance skin care products, but I don't mind the mild fragrance it gives. Works beautifully without any reaction. I have faced problems with a lot of vitamin C products but not this one. It's expensive, but if that's not a concern for you, it's definitely worth a buy! My skin type - Combination skin, sensitive, gets clogged easily. Also, the product has a water like consistency and doesn't feel like there's any layer on your skin, so even for oily skinned people, it should work just fine! I hope this review helps.

It has a nice texture and is easy to apply. Just not sure whether it has the brighten effect but I guess it takes time to find out. One big plus of this product is that it works well under my makeup or some sunscreen.
