about base18

what is base18?

Base18 is a science-led skincare brand founded by chemical scientists, built for sensitive, stressed and reactive skin. Every formula is developed from barrier science upward, using our own patent-pending delivery technologies — with no fragrance, no drying alcohols and no compromise on performance.

what is hypochlorous acid and is it safe?

Hypochlorous acid (HOCl) is a molecule your own body produces as part of its immune response — white blood cells release it to fight bacteria and calm inflammation. In skincare it's a gentle, skin-identical cleansing and calming agent, suitable for daily use on sensitive skin.

what does patent pending mean?

We've filed patent applications for our HydroFusion™ purification process and HydroSil™ two-phase delivery system. The technologies are developed in-house by our chemists — not licensed formulas with a new label.

are your products suitable for sensitive skin?

They're designed for it. All Base18 formulas are fragrance-free, alcohol-free, pH-optimised to the skin's acid mantle, and free from common irritants like phenoxyethanol and parabens. As with any skincare, patch testing is always a sensible first step.

product

hydrofusion™ rose mist

what makes it different from a regular rose water mist?

Most rose mists are just rose water. Ours combines pure Rosa Damascena hydrosol with boosted HOCl using patent-pending HydroFusion™ technology, so both actives stay stable and effective together — something a plain hydrosol can't offer.

can i use it over makeup or SPF?

Yes — it's designed for any point in your routine, including over makeup and SPF. Many users treat it as a midday refresh and setting step.

does it have a scent?

A subtle natural rose note from the hydrosol itself — no added fragrance, light rather than perfumed, and typically well-tolerated by people who react to synthetic fragrance.

product

acne clear spray

can i use it alongside acne treatments?

Yes. Acne Clear works well before serums, moisturisers and targeted blemish treatments, and alongside your existing routine.

can i use it on my body as well as my face?

Yes — face, chest, shoulders, back and anywhere prone to breakouts.

will it dry out my skin?

Unlike many traditional acne products, it's formulated at a skin-friendly pH with a mineral electrolyte complex, so it cleanses without the stripped, tight feeling.

product

hydrosil™ scar gel

how often should i apply it?

A thin layer twice daily on clean, dry skin — morning and evening. Consistency matters more than quantity.

can i use it on older scars?

Yes — HydroSil™ can be used on both newer and older visible scars as part of a consistent scar care routine.

does it feel heavy or greasy?

No. It dries into a lightweight, breathable, invisible finish that layers comfortably under SPF or makeup.
