1.e3The pH Miracle Myth

Everyone’s obsessed with this $18 bottle like it’s the second coming of Cetaphil. But I got curious about the “dermatologist-approved” label and found something that made me side-eye my bathroom shelf.

The formula banks hard on being pH-balanced — but that’s not the flex you think it is when the surfactants are doing the heavy lifting.

2.e6What You’re Actually Buying

It’s a gel cleanser from Prequel Skin, a brand that leans into the “cerebral skincare” aesthetic. The claim that got me? “Gleanser” — a portmanteau that promises gel-meets-cleanser with zero residue. $18 for 16.9 oz is a solid deal, but the marketing is doing a lot of heavy lifting.

5% Polyhydroxy Acid

Gentle exfoliation that doesn’t sting — but it’s so low it’s basically a whisper

2

Squalane

Adds slip so your face doesn’t feel like a chalkboard post-wash

3

Oat Kernel Extract

The “calming” agent that’s doing more for texture than inflammation

3.e1The Greenwashed Secret

Here’s where it gets sticky: the “clean” label hides a surfactant blend that’s harsher than they’d like you to think. Sodium cocoamphoacetate is a coconut-derived cleanser that can strip oily skin types if you’re not careful. The hero ingredients are good — but they’re not saving your moisture barrier from themselves.

  • Sodium Cocoyl Isethionate: The main foamer — effective but not gentle on impaired barriers
  • Glycerin: The humectant that’s doing 70% of the hydration work
  • Allantoin: A mild skin soother that’s barely there
  • Citric Acid: pH adjuster that’s technically an exfoliant — but don’t get excited

4.e5Texture & The First 3 Weeks

It’s a clear gel that lathers into a foamy cloud in about 4 seconds. Rinses off clean — no film, no squeak, just a muted “ah” feeling. First week I was into it. By week three, my T-zone started throwing tiny tantrums — small flakes I hadn’t seen since winter.

The surprise? It’s actually better as a morning wash than an evening one. Nighttime double-cleansing with this dried me out faster than my ex’s texts.

💡

One Thing: Use it only in the AM. Your PM routine needs something with more slip — this is a “wake up” wash, not a “makeup killer.”

5.e4Real Talk Results

My pores look marginally cleaner — like 15% less visible. But the flakiness was real, and I had to add a hydrating serum to compensate. It didn’t break me out, didn’t fix my texture, and didn’t ruin my life. It’s just… fine.

Worth it?
At $18, it’s a fair price for what it does — but don’t believe the “gentle for everyone” hype

6.e2The Final Wash

It’s a decent cleanser with a good price tag, but the “clean” marketing is doing more storytelling than the formula delivers. Buy it for your oily friend, not your sensitive one.
