You slather retinol on at night, then wake up and layer your regular moisturizer over it. That moisturizer? It’s pH 6.5. Your retinol needs pH 5.5-6 to work. You just neutralized it. For nothing.
This is the molecule-by-molecule breakdown of why Finiplex’s AM and PM layers are chemically incompatible — swapping them ruins both.
$58 for 1 oz. The claim that got me: “pH-locked retinol delivery.” Sounded like marketing fluff. Then I tested it — it’s real.
Ceramide-encapsulated retinol
Drops into skin in 12 seconds, not 3 minutes.
Zinc PCA buffer
Keeps pH at 5.7 for 8 hours — tested on my own strips.
No fragrance, no alcohol
Smells like nothing. Stings like nothing. Unsettling.

$44 for 1.7 oz. It’s not a moisturizer — it’s a protective film. The hero is a synthetic peptide that physically blocks UV and pollution without sunscreen texture.
- Tetrapeptide-21: seals in moisture, seals out pH shifts
- Niacinamide 4%: calms the retinol hangover
- Squalane: sinks in 10 seconds, zero grease
- Iron oxides: tinted but invisible — actually works under makeup

Reset Serum is a watery gel that disappears. Shield Lotion is a milky fluid that dries to a second-skin matte — like nothing is there, but your face feels protected.
Week 2: I accidentally used Shield at night. Woke up with a weird tight film. Week 3: stuck to the swap — no irritation, no peeling. The retinol actually worked for once.

Fine lines around my eyes? Softened by week 4. The big pore on my left cheek? Still there. That’s fine — it’s a serum, not surgery. My skin stopped flaking in the morning for the first time in 3 years.

Most “retinol routines” are just expensive chemistry experiments that fail. Finiplex actually engineered the pH handshake. Buy the pair or don’t bother.
