How To Use
How To Use
How to Apply the Korean Firming Serum
3 simple steps for maximum firming and wrinkle-erasing results
STEP 1: Prep Your Skin
Cleanse and tone as usual. Pat skin until slightly damp — damp skin absorbs EGF and NAD+ actives faster and deeper for maximum firming effect.
STEP 2: Apply & Firm
Dispense 2–3 drops onto fingertips. Gently press and pat (don't rub) across all 6 aging zones:
- Forehead and temples
- Under-eye and crow's feet area
- Smile lines and nasolabial folds
- Cheeks and cheekbones
- Jawline and jowl area
- Neck and décolletage
Use slow pressing motions — feel the watery formula absorb instantly and begin tightening on contact.
STEP 3: Let It Work
Wait 30–60 seconds. Feel the lightweight formula set. Follow with moisturizer to lock in the firming, plumping finish.
WHEN TO USE:
Morning & Night — apply after toner, before moisturizer
FOR MAXIMUM RESULTS:
Use twice daily. See visible line-smoothing in 7 days. Full firming and volume restoration in 30 days.
A little goes a long way. EGF and NAD+ are highly concentrated actives — 2–3 drops is all your skin needs.

"I've been getting Botulinum toxin every four months for three years. I picked this up on a whim and I'm genuinely shocked — the lines on my forehead look noticeably softer and my skin feels tighter than it did a week ago. I'm not canceling Botulinum toxin yet, but I'm seriously reconsidering. This serum is doing something real."
-
"I'm 54 and my skin had completely lost its firmness — my jawline was soft and my cheeks just looked flat and tired. Two weeks into this Korean Firming Serum and I genuinely don't recognize my face. Firmer. Fuller. More awake. I thought I needed filler. I needed this."
-
"The texture alone is unlike any firming serum I've tried — light as water but it absorbs and you can actually feel it working. But the results are what sold me permanently. My forehead lines look visibly smoother, my skin has that tight, bouncy feel I haven't had since my late 20s, and my $200 night cream is sitting unused. This is the one."
-
"I bought this specifically because I wanted the firming effect without doing actual Botulinum toxin. I was skeptical — nothing has ever delivered on that promise. By day 10, I was a complete believer. Softer lines. Tighter skin. Lifted appearance I didn't expect from a serum. Korean skincare really is on a different level."
-
"I was spending $250 every few months on Botulinum toxin just to keep the lines away. A friend sent me this serum and I haven't booked an appointment since. My skin looks firmer, my pores look smaller, and the forehead lines I'd accepted as permanent are genuinely fading. Best $40 I've ever spent on my face."
-
"Dull, loose, stressed-out skin — that was me six months ago. I started using this every morning and night and within two weeks something shifted. My skin looked awake. Lifted. Firm. My coworkers noticed before I even said anything. I looked it up and NAD+ is the reason — it literally recharges your skin at the cellular level and the results show. This is the only anti-aging serum I'll ever recommend."
