Centellian 24 PDRN Firming Boosting Ampoule (1.01 fl oz) - Improved Skin Elasticity by Dongkook Pharmaceutical. PDRN 300,000 ppm, Hydrolyzed Collagen & Elastin.

Excellent product, has a 30% higher concentration of PRDN than most popular brands out there (300,000 ppm). great for firming and barrier restoration. Amount will last about 2-3 months when once applied daily. Medium viscosity serum, with a tinted bronze color, lightly fragranced.Leaves a satin smooth finish, no sticky feeling residue.

Review follow up 5/15/26 One of the better PDRN serums for glow, moisture, barrier repair and minor, but noticeable wrinkle reduction. I’d recommend using in conjunction with Vitamin A (retinol) because the retinol in this product is not enough for me (almost 44year old female). I know this stuff works (for me) because when my monthly order did not come due to product being out of stock, my skin lost all of its glow and looked less plumped within a week or so! Only downside is noticeable price increases and occasionally out of stock…. Original Review (summer 2025) I’m almost 43 and my age is starting to show (fine lines, spots, a lovely 1 between my eyebrows) so I am in no mood to use products that aren’t effective! I’ve been using a more expensive PDRN serum (not sold on Amazon) that has been great for moisture and glow, but I ran out and needed one that was readily available and preferably a little cheaper, so I decided to go with Centellian24’s. Plus you can’t beat the convenience of Amazon shipping. I don’t care what anyone says, I think marine PDRN is better than vegan. I want the real deal, and this stuff seems like the real deal! 300,000 parts/million (ppm) is a pretty high concentration (the highest I’ve ever found is around 500,000, but the majority are under 10k, most even less than 5k) so this stuff is potent. Throw in some retinol and ceramides, and you have an amazing anti-aging serum that was a STEAL for the price (full disclosure I purchased during PrimeDays). I do wish CENTELLIAN translated the ingredient list without the need to use Google translate- sometimes it’s not 100% accurate. I also would like to know specific percentages of the other ingredients (retinol especially) but I’m not going to deduct stars just because this serum has really produced some great results. Because PDRN is the leading ingredient, this serum is on the thicker side, has a slight odor, and takes a little bit to absorb…but I’m ok with that! It’s very similar to the way other high quality PDRN serums smell and feel. Your skin might feel a bit tacky while it’s absorbing. I’d recommend using at night (because it has retinol, plus you won't have to wait to put makeup on, that is if you wear makeup). I’ve been using at night for about a week and I wake up to nicely hydrated skin, which makes lines not as pronounced. I’m very happy that I gave this stuff a try!

もちもちお肌になります！

I’ve been using this for a couple years now. Intermittently when I’ve run out, or didn’t think I was getting any results from it, I always start to notice the difference within a month or so. Consistency is key, like with all face products. My face is more supple and soft with this. It can feel sticky or thick at first when you put it on, but let your skin absorb it all the way and you’ll feel how moisture quenching it is.

PDRN is liquid gold!! I have sensitive skin but I have no issues with this product. Since starting this I have seen such an improvement in the texture of my skin. My face/neck are so smooth and hydrated. This is a great source of PDRN if you’ve been interested in trying it surly for the price.
