My ride-or-die vitamin C - effective, gentle, and consistently great
This is one of those products I keep coming back to and have repurchased monthly for years. Timeless Vitamin C has been a staple in my routine for a long time, and it is one of the main reasons my skin stays bright and even. The formula is straightforward and effective - 20% L-ascorbic acid with vitamin E and ferulic acid, no fragrance, no unnecessary fillers. The serum texture is very pleasant and lightweight, absorbs quickly, and layers well under the rest of my morning skincare and sunscreen. I’ve never experienced stinging, irritation, or sensitivity with this, even though my skin can be reactive if a vitamin C formula is poorly done. With consistent use, my skin looks clearer, more even-toned, and overall healthier. It helps keep post-acne marks from lingering and gives a noticeable brightness without feeling harsh or drying. A little goes a long way, and I appreciate that the ingredient list stays focused on proven actives rather than marketing extras. For reference, I have fair skin that is generally normal but leans dry in the winter, with a history of acne. I also use azelaic acid, retinoids, peptides, and hydrating serums in my routine, and this vitamin C plays very nicely with everything. If you’re looking for a no-nonsense, effective vitamin C that actually delivers results, this one has earned its permanent spot in my routine.

Don't give up, it's a good product and cheap.
The first 3 application, my face turn red and itchy. I stopped for 3 days, no redness & itchiness and my face skin was smoother, softer & brighter. So, it's good for my skin and I don't want to give up. Perhaps, I was using too much, so, I started using sparingly, hardly 3-4 drops of serum after 10 minutes, I applied Cerave moisturizer on top. Face was slightly red and after few days no side effects. Now I love this product because it's not just cheap but it's effective

GREAT PRODUCT / DISPENSER NOT SO GREAT
I give this product a 5 star. I have used the Timeless Vitamin C Serum for several weeks now and I am happy to report that I have had no bad reactions. I was concerned due to the high concentration of ingredients compared to other similar products. The serum is light and absorbs very well and leaves no sticky residue. I am very pleased. I give the dispenser a 2 star because the spray nozzle allows the serum to be wasted by spraying it on your hands. I recommend a dropper. By using a dropper, you squeeze a small amount directly on your fingers and then apply it on your face. I fixed this problem by emptying the serum into a small glass bottle with a dropper. It worked so much better. Less mess, less cleanup, and less waste. Also, I prefer having neutral dispensers in my bathroom so the bright yellow bottle did not fit my bathroom decor. It stood out like a thorn so I used a neutral dispenser. My bathroom counter looks so much better. Even though I love the concept of bright bottling, it's too different and too bright. I like simple.

Great product (The bottle/cap needs help!)
Product is amazing 10/10. It does what it says it does. It's brightening, gentle on the skin, feels nice on the skin, suitable for sensitive skin, quality formulation and my skin looks great because of it. You also get a great value for your money. You don't need to spend hundreds on an effective vitamin C, and trust me, I have shopped around. This does wonders for the skin. I gave it 4 stars because the liquid comes shooting out. It's vey watery and it's a pump/suspension, so you need to cup your hand around the opening when you pump it or else it flies and goes everywhere. This is not only annoying but also a mess. That part wasn't so thought out! Once they fix either the consistency or the way it comes out I will definitely give it 5 stars. All in all, I definitely recommend this product.

This serum is awesome! Tip: keep it in the fridge to maintain potency
Wow, I love this stuff! Super silky and moisturizing, and fits perfectly into my morning routine! Ive learned that vitamin C helps with UV sensitivity, so I apply it in the morning before my SPF....I use a retinol treatment at night, since using both Vitamin C and retinol can be irritating...perfect addition to my beauty regiment!

Better than Paula's Choice, The Ordinary and Derma E! Doesn't compromise skin barrier!!
I haven't written a ton of reviews but this product is worth writing one! I have tried different vitamin C products over the years and learned about this one from the Skincare subreddit and it does not disappoint! It's true it does have a bit of a smell that I'm not fond of but the results are honestly worth it. I also use Tretinoin 0.1% every other night and I alternate using this in between nights and I've seen a big difference in my skin. I also will use it in the mornings sometimes if I'm not going to be outside a ton since sunlight can degrade the efficacy of vit c. I sandwich it in between my CorsX Snail Mucin and my moisturizer before sunscreen and it really does give me a noticeable glow! It's a little watery but it absorbs quickly and the smell goes away pretty fast which is why I can get behind it. I've tried Derma E, TruSkin (NEVER AGAIN) The Ordinary, and Paula's Choice and this has by far been my favorite because of the price point and efficacy. It doesn't have as high of a concentration as other brands and does take time to work but because I also use a plethora of other serums I don't mind a lower concentration because it doesn't compromise my skin barrier. 10/10 would recommend!

Okayish vitamin C serum.
I used it for over three months and saw little to no difference. Maybe it required a much longer use. Dries quickly, smells alright and is lightweight. Might work for others but didn’t do much for me.

Compré este producto como uno de los dupes del CE Ferulic. La verdad hasta ahora funciona super, se absorbe muy rapido y la textura es agradable. Le da un brillo muy lindo a la piel. Comparando este producto con otras vitaminas C de precios similares este producto se siente mucho mas premium, y por ahora, siento que si puede ser un buen reemplazo del CE ferulic.

If the serum is not clear in color - do not use it! It is not effective and will cause irritation.

dopo molte ricerche sono finalmente approdata a questo siero e ne sono molto molto soddisfatta! usavo già sieri alla vitamina C e ultimamente avevo avuto dei buoni risultati con il truth serum di ole henriksen ma non mi era mai capitato di vedere un miglioramento così forte in meno di una settimana. lo uso la sera, come da consigli del fabbricante dopo aver pulito il viso con un detergente verde leggermente esfoliante di una linea verde da supermercato. non asciugo il viso, al massimo ci appoggio sopra l'asciugamano e aspetto che le gocce di acqua non cadano più giù. dunque, dicevo che pulisco il viso aiutandomi con una spazzolina e poi verso 2/3 pompette di siero nel palmo della mano, attenzione, è molto liquido! lo tengo in frigo per farlo durare di più e faccio assorbire il siero con movimenti prima circolari e poi picchiettando, riesco a metterlo anche su occhi e intorno alle labbra ma non so se chi ha una pelle meno abituata alla vitamina c potrebbe fare lo stesso. nel frattempo continuo le mie abluzioni serali, passano circa 10 minuti insomma e poi metto sul viso dell'aloe vera al 99% che tengo sempre in frigo e massaggio fino ad assorbimento anche quella. se ho qualche brufoletto con un dischetto di cotone, e solo nella zona T oppure solo sul brufolo, metto del tea tree oil naturale al 100%, massaggio un pochetto anche quello. se ho la pelle molto stressata e secca metto una noce minuscola di idratante per sigillare tutti gli attivi all'interno della pelle. Alle volte dopo aver lavato il viso, soprattutto se sono stata molto al pc, passo con un dischetto di cotone del tonico alle rose (mi rinfresca e gfa sgonfiare gli occhi), se sono in previsione di quei giorni, un tonico alcolico. la mia pelle è subito più liscia e luminosa e l'indomani mattina è perfetta, mai avuta una pelle migliore! Per tutto il giorno è meravigliosa! Tra qualche giorno provo a incorporare una crema al retinal, inizierò con un'applicazione 2 volte a settimana e poi vedrò come incorporare il siero. Altra cosa: a me il siero è arrivato in perfette condizioni, nuovissimo e trasparente, quando diventa arancione allora significa che si è ossidato e non funziona più. ottimo prodotto e ottimo prezzo dati i risultati e gli ingredienti, pochi e buoni. non tornerò più indietro, è vero che il siero alla vitamina c dà il meglio di sè con la vitamine e e l'acido ferulico. per ora ovviamente non ho visto risultati sui segni di espressione ma chimicamente l'unica sostanza che agisce bene su quelle è l'acido retinoico, intanto ho una pelle sana e luminosa e liscia e morbida da favola!
