UK-based skincare brand Skin Rocks has launched The Strong Acid, a high-strength exfoliating toner positioned as a "next-generation" acid treatment.
The product sits at the top of the brand's three-tier toner range, joining The Gentle Acid and The Control Acid, alongside the performance-enhancing essence The Amplifier.
Join European founders, operators, and investors who read The Checkout every week.
The Strong Acid combines alpha, beta, and polyhydroxy acids in a single formula:
- AHAs: glycolic, lactic, and mandelic acids
- Supporting acids: shikimic and phytic
- PHA: gluconolactone, for gentler resurfacing
- BHA: salicylic acid, to clear congestion
Skin Rocks was founded in 2022 by Caroline Hirons, one of the UK's most influential beauty voices. Hirons began her career in retail before building a significant following through her blog (launched in 2010) and her social channels, and has since translated that creator authority into a results-focused product line.
The Strong Acid is available now via skinrocks.com.
