🧪 **Dry Face, Don’t Play**
You’re ruining your vitamin C. Damp skin dilutes it—turns a 40% bomb into a 20% fizzle. This serum needs *nothing* between it and your face. No toner mist. No dampness. Straight onto bone-dry skin. I wait 3 minutes after washing. Absorbs in 8 seconds flat. That’s the difference between glow and meh.

👆 **The 40% Punch**
$48. South Shore Skin Care claims “professional-grade brightening.” I rolled my eyes. Then I tried it. It’s not a serum—it’s a formula with an attitude.

1. **Anhydrous base** – No water. Means it doesn’t oxidize in 3 weeks like every other C.
2. **THD ascorbate** – Not the cheap L-ascorbic acid that stings. This one’s oil-soluble, sinks in, doesn’t pill.
3. **pH 5.5** – Low enough to work, high enough to not burn your face off.
