I Tried That Viral TikTok Serum for 30 Days. Here's My Honest Review.

If you’ve spent even five minutes on TikTok lately, you’ve probably seen that one “miracle” serum everyone’s talking about. You know the one — every beauty influencer swears their skin started glowing overnight, fine lines magically disappeared, and acne marks just… vanished.

I Tried That Viral TikTok Serum for 30 Days. Here's My Honest Review.

So, naturally, I had to try it.

For the sake of transparency, I’m not one to jump on every viral beauty trend — I’ve learned the hard way that what works for one person might not work for another. But this serum had way too much hype to ignore. So I decided to put it to the test for 30 days and see if it really lived up to the buzz.

Here’s how it went.


The Product

Let’s start with what we’re actually talking about — the L’Oréal Paris Revitalift 1.5% Pure Hyaluronic Acid Serum. It’s one of those serums that went viral for giving people instantly plumper, glassy skin. Everyone from skincare beginners to dermatologists seemed to love it.

It promises deep hydration, smoother texture, and that healthy “just-had-a-facial” glow. And honestly, the ingredient list looked promising — hyaluronic acid for hydration, plus glycerin to help lock in moisture. No harsh actives, no strong fragrance, and suitable for all skin types.

Week 1: The “Testing the Waters” Phase

During the first week, I used it every morning and night after cleansing and before moisturizer. The texture felt silky but not sticky, and it absorbed in seconds.

Right away, my skin felt softer. Not dramatically different, but that kind of bouncy hydration that makes you keep touching your face (which, by the way, you shouldn’t).

No irritation, no redness — which was a relief because my skin can be sensitive. I didn’t notice any major glow yet, but it definitely made my moisturizer work better.


Week 2: The Subtle Glow Appears

By the second week, I started noticing changes. My skin looked more even, and that dull, tired look was fading. It was giving “well-rested” energy — even on days I wasn’t.

I also realized I didn’t need as much foundation. My skin looked hydrated enough that a tinted moisturizer was plenty. The fine lines around my mouth and under my eyes seemed a bit smoother, too.

This was the point where I started thinking: Okay… maybe TikTok was onto something.


Week 3: Hydration Mode Fully Activated

This was the week it clicked. My skin started looking dewy all day long. Not oily — just radiant. You know that glow where light seems to bounce naturally off your cheeks? That was happening.

Even my friends asked what I was using — which, honestly, is the best kind of compliment.

I also noticed my makeup went on more seamlessly. Foundation didn’t cling to dry patches, and I didn’t need to touch up as much during the day.


Week 4: The Final Verdict

After 30 days, I can confidently say this serum delivers. It’s not magic, but it does exactly what it promises — hydration, smoothness, and a visible glow.

It didn’t completely erase texture or dark spots (let’s be real, no serum can do that in a month), but my skin looked healthier overall. Softer, plumper, and more balanced.

What I loved most? How easy it was to layer with the rest of my routine. It never pilled under sunscreen or makeup, and it worked well both morning and night.


What I Didn’t Love

Because this is a real review — not a sales pitch — here’s what I didn’t love:

  • The bottle ran out a little too quickly for daily use twice a day.

  • The dropper can sometimes get messy.

  • It’s great for hydration, but if you’re looking for brightening or anti-aging beyond fine lines, you’ll need to pair it with another serum like vitamin C or retinol.

Would I Repurchase It?

Absolutely — especially for days when my skin feels dehydrated or tired. It’s one of those easy, no-fuss serums that just works, no matter what else you’re using.

If you have dry, combo, or even oily skin that needs a hydration boost, this one’s a safe bet. Just remember to seal it in with moisturizer — hyaluronic acid works best when it has something to hold onto.


Final Thoughts

Sometimes, TikTok trends are pure hype. But every once in a while, one actually earns its spot in your routine — and this serum did.

After 30 days, my skin feels healthier, looks brighter, and honestly, I’ve stopped overcomplicating things. It’s a reminder that skincare doesn’t always need to be fancy or expensive to be effective.

If you’re craving that real glow — not the kind you fake with highlighter — a simple hydrating serum like this might just be your new best friend.

Because sometimes, the internet does get it right.
