  Amazing! Youthful Skin & Oil Blocker For Me!!

  I love PDRN skincare, but my skin usually doesn't feel the same. I don't know what it is, but my skin can get crazy oily after using it. I have other COSRX products that I really enjoy, so figured I'd try this and see if it would be any better. Y'all, my skin LOVES this serum! Not only does this soak in and leave my skin more matte feeling, but it tames my oil! I don't know what is in this that's doing that, but wow; totally amazing side benefit. This makes my skin look glowy, instead of "help me, I'm melting." This has become my go to product for both nighttime and daytime use just for this alone. It also seems to be tightening my pores (maybe that's why there's way less oil?) and my skin feels healthier. Another COSRX win! This will be another one I'll need to keep buying. Highly recommend!

  0.2% (2,000 ppm) Sodium DNA is significant

  This "5 PDRN Collagen Intense Vitalizing Serum" is part of a newly launched line that also includes a toner and mask, but the serum does really well on its own. The formula produces what feels like a very light essence with a thin gel structure. It spreads easily, loses most of its slip almost immediately, and then leaves behind a film that is neither tacky nor squeaky. As it settles, some softness returns and it layers smoothly under my other PM products. There is major focus on a concept of "five PDRN origins", but the ingredient list tells a much more important story. The Korean panel specifies Sodium DNA at 2,000 ppm, which is a meaningful concentration for a cosmetic formula. It is much higher than the trace levels often seen with other products in the marketplace, and it sits alongside niacinamide, panthenol, betaine, collagen, and a long hyaluronic blend. Together these create a straightforward recovery-focused serum that supports hydration and general skin resilience without any heaviness. The texture is extremely lightweight, almost like a toner with a small amount of structure. Massaging it in gives the most even finish, and it works especially well for me as part of my PM routine. I avoid sheet masks and heavier occlusive steps, so this fits neatly into my rotation as a mid-layer that adds a subtle boost to nightly recovery. It has been very easy to use consistently and has integrated into my routine without any complications. This is an essence-weight serum built around a real active concentration, with a simple and comfortable feel on the skin.

  Where have you been?

  Huge Cosrx product user & I love how their products make my skin LOOK, FEEL & HEAL. I was so excited to try this serum! Skin Type: Melanated, Almost 30 & Sensitive. This 5 PDRN Serum did NOT disappoint. I took the time to use it for a week in my Day & Night skincare routine, layering it with different products & I'm highly impressed. 🟢Most notable points:🟢 - Fragrance-Free This is very important for those with sensitive skin or maybe you don't like scented face care products. I had no adverse reactions to it & did not break out. - Hydrating & Moisturizing My skin is left feeling so soft, supple & moisturized after one use. Leaves it with a subtle glow. - Consistency Like thicker water. It's not heavy by any means. This Serum is definitely on the lighter end. - Ability to layer with different products I tried this serum with 9 other products. This included moisturizers, other serums, oils, overnight masks etc. It blended with all of those products, still melting into my skin. Very pleased with the versatility of this product. Overall I am thoroughly impressed with the results it gave my skin. I got many compliments when using this product. My face appears brighter, glowy, hydrated & refreshed. I have nothing negative to say about this serum as I got only positive results. I will be repurchasing once this bottle runs out & I recommend it to anyone looking for a versatile PDRN serum that delivers!

  Dries non-sticky, intensely moisturizing

  This review is for COSRX 5 PDRN Collagen Intense Vitalizing Serum, which is made in Korea. This is a serum that dries non-sticky! It provides great moisturization as I used it overnight and could still feel the suppleness and plumpness in the morning when I woke up. It did not cause pilling or any bad reactions with my other products layered underneath. The serum is unscented and my only complaint is the pump is very short so you need to tilt the bottle to get it on the skin. This is not a problem when the bottle is full but when you get to the bottom the straw will not reach the last bits if you have to tilt the bottle. The pump barely extends past the edge of the cap, which s an awkward oval for no discernable reason… who designed this? At a price of $25.00 for 3.38 oz, I think this is a great value for the money and another winner from the brand. I actually look forward to using this daily. I did not experience any irritation when using the product and you can see the ingredient list in the final image.
