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.

Worth it!
Bought this after seeing lots of social media attention. GET IT! Works and well. I have sensitive rosacea prone combination-oily skin in my 40s. after a slight adjustment my skin loves it. I’m noticed a brightening. Absorbs well. After it dries you’re good. No tackiness at all. Does have a ‘hot dog water’ (doctorly podcast description and very accurate) scent that dissipates quickly. It is a bit watery, so there is a slight learning curve for how much to apply and best method for you. Wears well under makeup and other skin care. Will purchase again.

Great value, but could improve texture.
This product seems to be doing its thing. It’s a bit more gentle than what I’d like but skin seems smooth and hydrated.y skin was pretty even to start, so I can’t say I’ve seen any drastic change with brightening or tone. Mostly wanted the antioxidant. My only complaints are the smell is like liquid smoke and it is fluid. This is not a serum, so don’t go crazy with the press on your first use because 3oz will come out.

Different formula
I used this product for a few years now. Used over 5 bottles. It always had yellowish tone and smelled like tomatoes to me. My skin was bright and I was happy with the results. However the last time I bought this serum I was disappointed. The liquid is completely clear and it has weird odor. Smells like chemical and it burned my skin right after i applied it. I think they changed formula or something is off with this batch. So sad. If that’s their new formula I won’t be using it again:/

Works beautifully on teenage acne prone skin
Ordered this for my son who has had prominent acne for quite some time. He has tried everything! He recently switched to a new cleanser and moisturizer which was slightly working but this serum seems to have really made the difference! His skin is clearing up and now looks smooth, moisturized and healthy.

Holy grail
This is my second time purchasing this serum. The first time I used it, I noticed a HUGE difference in around 30 days, as advertised. I personally use it at night. My sister thought I got Botox (which I haven’t.) but it gives you the “glass skin” people rave about online. I tried the 20% after I finished the first bottle, and it irritated my skin a little. I stopped using it for a few weeks. I could definitely tell a difference, and not a good way. So I went back to the 10%. MAN. This stuff is HOLY GRAIL STATUS. My skin is so much happier with the 10%, maybe I can start adding the 20% back in (I’d love to go full 20% one day) but… for now… this is great. Smell is a bit weird but it doesn’t linger. I keep it in the fridge. It’s a nice cold serum. I apply it after my cleanser and before my moisturizer. 10/10. do yourself a favor and get it. (Not a paid review.)

オバジより良い
オバジを使っていましたが、私には刺激が少し強く続きませんでした。 こちらは10%ビタミンCなのに刺激を感じにくく、毎日ストレスなく使えています。 さらっとしたテクスチャーで、ベタベタや油膜感が残らないのが本当にお気に入り。 3週間くらいで肌の印象が明るくなり、毛穴も以前より気にならなくなったように感じています。 冷蔵庫保存なのが少し手間ですが、品質を考えると納得です。むしろ朝のひんやり感が気持ちいいので、今ではそれも楽しみになっています。

Bueno pero no el mejor.
Está bien, muy buen empaque, llego a tiempo, sin embargo no es la galenica de mi preferencia para la vitamina C (muy acuoso), los resultados me parecen más discretos en comparación a los obtenidos con otras marcas, aunque me parece buen producto.
