SkinTrendPrequel Universal Skin Solution Review: Hypochlorous Acid Spray Breakdown
Prequel's Universal Skin Solution is a 0.02% hypochlorous acid spray for face and body. Here's its formula, sizes, price per ounce and how it compares.
Prequel’s Universal Skin Solution is a mid-priced hypochlorous acid (HOCl) spray for face and body, and one of the few that clearly publishes its concentration. It sits between budget Magic Molecule and premium Tower 28 on price.
At a glance

What’s in it
Prequel’s official ingredient list is three items: purified water, hypochlorous acid and sodium chloride (salt). That’s as simple as HOCl sprays get, with no fragrance or extra botanicals to react to.
The standout is transparency. The brand states its concentration (0.02%) and explains how it converts to about 270 ppm of free available chlorine. For context, Prequel’s blog notes that US wound-care HOCl solutions typically range from 100–200 ppm. These figures come from the brand; we haven’t seen independent lab testing.
Who it’s for
- People who want to know exactly what concentration they’re using
- Face and body users. The 8 oz Jumbo makes sense for that
- Sensitive-skin users who prefer a three-ingredient formula
Pros and cons

Verdict
Prequel is a solid middle-ground pick: a three-ingredient formula, a published concentration and a reasonable price, especially in the Jumbo size. If you want the cheapest option, go with Magic Molecule. If you want the eczema-association seal, go with Tower 28.
