said scar appearance visibly improved after 8 weeks of consistent use*
"I had a surgical scar on my abdomen that I'd been trying to improve for over a year. Nothing worked, silicone sheets were uncomfortable and I couldn't stick to using them. HydroSil was the first thing I could actually use consistently. After eight weeks the difference is visible. It's flatter, less red and I've finally stopped covering it up."

said skin felt calmer and less reactive within 2 weeks of daily use*
"I've had sensitive, acne-prone skin my whole adult life. Every product either didn't work or made my skin worse. I was genuinely sceptical about a spray but I'd run out of options. Within two weeks of using Acne Clear morning and evening my skin started calming down. A month in and I'm using less foundation than I have in years."

reported skin felt visibly calmer and more balanced after 4 weeks of daily use*
"My skin always felt reactive, tight, and constantly flushed, especially after workouts or long days outdoors. Most hypochlorous sprays felt too clinical or drying, but Base18 Rose Mist instantly felt calming and refreshing. Within days, my skin looked less stressed, more balanced, and noticeably calmer throughout the day."

said the formula absorbed completely with no sticky or greasy residue*
"I had a raised scar on my arm from a procedure that I'd been trying to flatten for over a year. HydroSil was different — it absorbs completely, no residue, no discomfort under clothing. After ten weeks of using it twice daily the scar is visibly flatter and the redness has reduced significantly."

our approach
Most clinical brands treat symptoms. Base18 treats root cause — barrier dysfunction. Every formula is built from barrier science upward, using patented delivery systems, disclosed actives, and no unnecessary irritants. No fragrance. No drying alcohols. No compromise.
hydrofusion™ technology
HydroFusion™ is our patent pending purification process — stabilising hypochlorous acid in a botanical hydrosol that would normally degrade it on contact. It enables 96.8% Rosa Damascena flower water alongside clinically effective HOCl in a formula stable throughout its shelf life. No other brand has solved this problem the same way.
fragrance & alcohol free
Fragrance, drying alcohols and phenoxyethanol have no therapeutic benefit in skincare — they exist for texture and sensory marketing at the expense of the barrier they claim to support. Base18 formulas contain none of them. Not as a positioning exercise — because barrier repair requires eliminating every avoidable irritant source. And these are all avoidable.
the technology
built in the lab. proven on skin.
HydroFusion™
Stabilises hypochlorous acid inside pure rose hydrosol — actives that would normally cancel each other out, working in harmony.
HydroSil™ two-phase
A breathable silicone film with actives dispersed inside it — continuous barrier protection and active support in one gel. Patent pending.
HOCl
Hypochlorous acid is what your white blood cells release to cleanse and calm. Skin-identical, gentle, effective.
