Hannah De Vries from Amsterdam, Netherlands –
Bij het zoeken naar een effectieve vitamine C-serum was ik aanvankelijk skeptisch. In Nederland hoor je veel over de wonderschappen van deze producten, maar er zijn ook talloze tegenvallers. Nadat ik COSRX The Vitamin C 13 Serum had uitgeprobeerd, merkte ik echter al snel dat mijn huid egaler aanvoelde en zelfs fijne lijntjes zichtbaar verminderd waren na enkele weken gebruik. Wat me echt opviel is hoe het product daadwerkelijk hydraterend werkt – in tegenstelling tot sommige andere serums die voor mij vaak droogte veroorzaakten.
Dit serum voelde niet alleen aangenaam fris aan tijdens toepassing; tegelijkertijd verbeterde de structuur van mijn poriën geleidelijk—ik had nooit verwacht zulke resultaten te zien!

Navigating through countless skincare options can feel like searching for a needle in a haystack, but I finally landed on COSRX The Vitamin C 13 Serum here in Toronto. Over the past four weeks of incorporating it into my morning ritual, I’ve witnessed remarkable changes. It penetrated deeply to illuminate dull patches and revitalized hydration that I’d thought lost to our dry winters. Fine lines near my eyes have softened as well! My complexion feels firmer with fewer noticeable pores—a quality many serums fail to deliver despite high expectations. With its soothing formulation full of pure vitamin C minus irritating additives, it is versatile enough even for sensitive souls amid bustling urban life.

As someone who thrives in the bustling streets of Mumbai, I’ve experienced the skin troubles brought on by humidity and pollution. A month into using COSRX The Vitamin C 13 Serum, I felt an invigorating shift! Initially skeptical about vitamin serums due to previous experiences with oily residues or irritation, this gem truly stood out for its lightweight consistency. After consistently applying it each morning alongside my yoga routine at dawn, I’ve noticed not just reduced pigmentation but also a newfound clarity in my complexion. Blemishes that once plagued me during monsoon seasons are gradually disappearing—gone is the dullness! Even friends have commented on how vibrant my face looks as we catch up over cups of cutting chai in Colaba!

I’ve been using COSRX The Vitamin C 13 Serum for about three weeks now, and I’m impressed with the results. This serum contains pure vitamin C, which has significantly improved my skin texture. I’ve noticed a visible reduction in redness and dark spots that have plagued me for years. It feels lightweight on my skin and absorbs quickly without leaving any greasy residue. Additionally, it is low-irritant, so I can apply it daily without worrying about irritation—my sensitive skin loves this formula! It’s definitely a staple in my skincare routine now.

I just gotta say, this COSRX The Vitamin C 13 Serum has totally surprised me! I picked it up on a whim since my skin’s been looking kinda dull lately. Right off the bat, you can feel that moisture kick in—like instant hydration. After using it daily for about three weeks now, I’ve noticed my skin looks brighter and those pesky blemishes are really starting to fade. I love how lightweight it feels too; it’s not sticky at all which is fab! Plus, I’m pretty sure my pores look smaller? Major win there! Can’t recommend enough if you’re keen on keeping your skin fresh.
Emily from Los Angeles, USA –
After using COSRX The Vitamin C 13 Serum for about three weeks, I am thoroughly impressed with the results. This serum contains pure vitamin C which helped improve my skin’s elasticity and reduce redness significantly. I’ve noticed a substantial decrease in dark spots and an overall brightening of my complexion. Its lightweight texture absorbs quickly without any irritation, making it perfect for daily use. The moisturizing properties kept my skin hydrated throughout the day as well. Overall, it’s become a staple in my skincare routine.
Samantha from Austin, USA –
COSRX The Vitamin C 13 Serum is an impressive addition to my skincare routine. I was drawn to its low-irritant formula and the promise of reducing blemishes within weeks. After using it consistently for a month, I’ve noticed significant improvements in my skin texture and reduction in red spots. It has definitely improved hydration levels, making my skin feel plumper. Plus, the antioxidant benefits seem effective as well; I love knowing I’m fighting free radicals too! This serum absorbs quickly without leaving any residue behind—perfect for daytime use.
Jenna from Adelaide, Australia –
I gotta say, I’ve been using COSRX The Vitamin C 13 Serum for a few weeks now and I’m pleasantly surprised. This stuff really works wonders! My skin feels so much smoother, like seriously baby soft. I noticed my pores looking smaller too, which is a game changer. It’s super lightweight and absorbs quickly – no sticky feeling whatsoever. The brightening effect is real; it has lightened some of the dark spots I had lingering from last summer’s sunbathing session! Just a heads up: start slow if your skin’s sensitive since it’s packed with pure vitamin C – but it hasn’t bothered me at all. Honestly, if you’re in the market for an affordable yet effective serum that doesn’t break you out or leave residue behind, give this one a go! Really loving how my complexion looks lately.
Jasmine from Portland, USA –
Alright, so I’ve been using COSRX The Vitamin C 13 Serum for a little over a month now, and let me tell you—I’m kinda blown away! I was super skeptical at first since I’ve tried plenty of serums that just didn’t cut it. But this one? It’s smooth as butter on the skin. My favorite part has to be how hydrating it feels without any greasy residue. I noticed my blemishes starting to fade after about two weeks; they weren’t kidding about fixing spots! Plus, my skin’s felt way firmer around the eyes which is honestly such a relief considering all those late-night Netflix binges (oops!). All in all, it’s definitely becoming a staple in my routine—just gives me that fresh glow every morning. Definitely recommend giving this one a whirl if you’re lookin’ for some vitamin C magic!
Lily from Melbourne, Australia –
Honestly, I’ve tried a few Vitamin C serums in my time, but COSRX The Vitamin C 13 Serum really takes the cake! After just four weeks, I’ve noticed significant improvement in my skin’s texture. My blemishes are fading and those pesky dark spots seem less visible—like they’re going into hiding! What I love is that it doesn’t irritate my sensitive skin at all. It’s super moisturizing too; no more dry patches for me. The lightweight formula absorbs quickly and keeps my face feeling fresh all day long. Plus, it feels good to know I’m using something with solid antioxidant power!
