NAD+ EGF Firming Serum

I discovered K-beauty about six months ago, and this has become one of my go-to serums. Their ingredients are always high-quality, and I appreciate that they fully disclose all of them on each box. The texture of this firming serum is light and silky. It absorbs quickly with no greasy look or feel, and doesn't leave my skin feeling sticky. It layers perfectly under sunscreen and makeup with no pilling. You don't need to use very much either, so the bottle will last quite a while. It feels gentle, and my skin didn't feel irritated or look red at all, just well hydrated.

I've been loyal to their pink PDRN serum for the past 8 months (I'm already on my third bottle because it's THAT good), so I had high expectations for this one and somehow, it exceeded every single one. From the first few uses, my skin felt smoother, firmer, and so much more radiant. It has that perfect lightweight texture that absorbs beautifully without feeling heavy, sticky, or greasy. My skin looks plumper, more refined, and just overall healthier. I've noticed improvements in texture, firmness, and even those little fine lines that creep up over time. What I love most is that it delivers serious results while still being gentle and non-comedogenic, so my skin stays happy and clear.

I'm 38 and I started noticing the smile lines first. Three weeks in and they look softer. Not gone but visibly less deep. The texture is so light I forget I'm wearing it under moisturizer.

I was about to book a filler appointment for my nasolabial folds and decided to try this first. Glad I did. Saved myself $600 and my face looks more lifted than I expected.

My skin is glassy after one drop. I've been getting compliments at work which never happens. The red color of the serum is gorgeous too.

47 here. I've tried everything from drugstore retinols to $200 La Mer. This actually delivered on the firmness claim. My jawline looks more defined in the morning.

NAD and EGF have been all over my feed for months. Finally tried it. Skin is plumper and that hollow look around my eyes is starting to fill in.

absolutely love. lightweight, doesn't pill under foundation, smells like nothing. my forehead lines are softer after 2 weeks of consistent use.

My esthetician asked what I changed. That's the highest compliment I can give a product. She wanted the name immediately.

I'm a skincare snob and this passed my test. The watery texture is luxurious. Skin looks glassy and bouncy by morning. Will repurchase.

42 and have been getting Botox in my forehead for years. I tried this between appointments to stretch them out and honestly might cancel my next one. Forehead looks smoother than expected.

good but pricey. results are real though. fine lines around my eyes are softer. wish the bottle were bigger for the cost.

I have sensitive skin and was nervous about trying anything with growth factors. Zero irritation. Just plumper, more glowy skin. Three weeks in.

My husband noticed before I did. He said my skin looked different and asked what I was doing. That's literally never happened in 12 years of marriage.

Layered under my SPF and makeup with no pilling at all. Some serums roll off — this absorbs in seconds and disappears. Skin looks dewy by 2pm.

Lip lines were my biggest concern and they look softened. Not gone but you can tell. Pat it gently along the upper lip area.

50 years old and my skin has more bounce than it did at 45. I credit this serum and good water intake. Use it morning and night.

obsessed with the dropper. very precise. you only need 3-4 drops for the whole face. one bottle has lasted me almost 6 weeks.

I have been using growth factor serums since the early SkinMedica days. This one holds up against products triple the price. Plumping effect is real.

My crow's feet are the first thing I notice in selfies. After 3 weeks they look softer. Not invisible but visibly improved.

I'm 32 and trying to be proactive instead of reactive. Started using this before the deeper lines set in. Skin looks brighter and feels firmer at the jaw.

It really is a glass-skin serum. The dewy finish lasts under makeup. I've stopped using my hydrating mist because I don't need it.

My mom (62) has been using mine secretly. She finally confessed and now I'm ordering her a bottle. She said her smile lines look softer.

Honestly skeptical of all the NAD hype but I caved. Worth it. My face looks more rested and my skin feels firmer in the mornings.

4 stars only because I wanted faster results. By week 3 they were undeniable but week 1 I was unsure. Stick with it.

My foundation looks better on top of this serum than it has on top of any primer. Skin is just smoother to start with.

I had two friends compare my before and after at month one and they were shocked. Lines around the eyes definitely look softer.

Pat it in until fully absorbed and your skin will thank you. The viscous red liquid looks intimidating but it sinks in fast.

My makeup artist friend used this on me before a photoshoot and asked if I'd had a facial. The dewy bounce is real.

I'm 45 and have had two rounds of microneedling this year. This serum makes my skin look post-treatment without the downtime.

I love that the red color is from natural ingredients. No synthetic dye, no fragrance, no irritation. Highly sensitive skin approved.

Skin volume around my cheeks looks more lifted. I had hollowing starting under my eyes and that's looking less pronounced.

K-beauty is on a different level when it comes to formulating actives. This is no exception. Top 3 anti-aging serum I've tried.
