Prept Hypochlorous Acid (HOCl)
£18.50
Not all HOCl is made equal
Hypochlorous acid is a molecule your own skin’s defences produce naturally. How it’s manufactured decides how pure, stable and gentle the final product is. Prept is made in the UK by an advanced proprietary electrolysis process using only purified water and medical-grade salt. It contains no added acids and no bleach, and it’s free from alcohol, fragrance, preservatives and stabilisers.
99.6% purity, independently validated
Near-neutral pH (6.25–7.4), gentle enough for sensitive and reactive skin
18-month shelf life (6 months once opened)
Made in the UK to ISO 9001, ISO 13485 and ISO 14001 standards
Who it’s for
Prept is trusted by skin professionals to cleanse the skin before, during and after treatments. It’s also available in a take-home size, so patients can keep caring for their skin between appointments.
