🧼 **AM or PM? Pick a Lane**

This cleanser has four exfoliating acids. That’s a lot. So no, you shouldn’t use it twice a day unless you want your face to feel like a peeled grape.

The real trick? It’s not about AM vs PM. It’s about *what else you’re using*.

☀️ **Morning? Only If You’re Brave**

$38 for 5 oz. The claim: a single foam that exfoliates, cleanses, and “brightens” in 60 seconds. I bought it because I’m lazy and wanted one step to do three things.

1. **Acid Cocktail** – Glycolic, lactic, salicylic, and mandelic. That’s four ways to strip your barrier.
2. **Foam That Actually Bubbles** – Pump once, it turns into a thick mousse. Not watery. Not thin.
3. **No Waiting** – You don’t leave it on. Lather, rinse, done. That’s rare for acids.

🌙 **Night Is the Sweet Spot**

This is a PM-only product for 90% of people. The acids work while you sleep. Using it in the morning means you’re naked against the sun — unless you’re a reapply-every-2-hours sunscreen zealot.

  • Glycolic Acid: The workhorse. Unclogs pores, fades spots. Also stings if you overdo it.
  • Lactic Acid: Gentler. Hydrates while exfoliating. The buffer.
  • Salicylic Acid: Oil-soluble. Gets inside pores, not just on top.
  • Mandelic Acid: The largest molecule. Slow, steady, less irritation.

🔬 **Feels Like a Spa Mistake**

Texture: thick, creamy foam that dissolves into nothing in 30 seconds. First pump, I thought my face was clean but tight. Too tight. That’s the glycolic doing its thing — and a warning.

Week 2: My chin texture flattened. But my cheeks got shiny-reactive. Turns out, using it after a retinol night is dumb. Don’t be me.

💡

One Thing: Wait 10 minutes after cleansing to apply anything else. Your skin needs to reset pH or it’ll sting like hell.

⚠️ **The Before & After No One Talks About**

Measurable: fewer closed comedones on my jawline. Less oil at noon. What stayed: my nose pores. They’re still there. No cleanser fixes that.

Buy if
You have oily, congested skin and use zero other exfoliants.
⏭️

Skip if
You’re on tretinoin, Accutane, or have eczema. Your barrier will riot.
💰

Worth it?
For $38, yes — but only if you use it right. One pump lasts 3 months.

✨ **Final Call**

Use it at night, three times a week max, and don’t chase the tingle. The tingle is your barrier waving a white flag.
