Cleans without stripping
A physiological pH of 4.5–5.5, identical to healthy skin. Against the pH 9–10 of a conventional soap, it doesn't strip your skin barrier and leave you feeling tight.
Restore your skin's natural balance. A solid soap with natural actives and a pH identical to healthy skin.
Conventional shower gel isn't designed for sensitive skin. Detergents that strip the natural protective layer, fragrances that trigger reactions and an alkaline pH that unbalances the microbial ecosystem of your skin. You feel the result: dryness, tightness, itching, redness.
Your skin isn't «dirty». Its barrier is weak.
Not another reformulation. It's a solid cleanser made with natural actives and beneficial strains of natural origin: the ones your skin recognises and works with best.
A physiological pH of 4.5–5.5, identical to healthy skin. Against the pH 9–10 of a conventional soap, it doesn't strip your skin barrier and leave you feeling tight.
Actives that are alive and functionally active: they reach your skin able to work. They aren't dead extracts or filler derivatives that stay on the label.
Natural extracts with a calming, hydrating action, to support the daily cleansing of skin that's already reactive.
Most «natural» soaps carry actives that can no longer do anything: they arrive in the bar switched off, or are lost long before they touch your skin. They stay on the label.
Heta Lab works the other way around. We select each active and design each bar so it arrives alive, protected and active on your skin. How we do it is our craft; you just feel the result.
Healthy skin lives at an acid pH, between 4.5 and 5.5. The Heta Lab formula respects that range: it lifts dirt and excess oil and leaves the protective mantle intact. No tightness when you step out of the shower.
pH 4.5–5.5 vs pH 9–10As you wash, natural actives settle on the skin instead of stripping everything away. They work with your microbiota — your first natural defence — and respect it with every shower.
Natural actives that stay activeNatural extracts support the process with a calming, hydrating action. Your skin comes out clean, yes — but also soft, comfortable and balanced. The difference isn't on the label: it's how you feel afterwards.
Natural extractsTruly clean, but never dry. Softer and calmer. Balanced and comfortable. That's all a daily cleanse should do — and all that conventional cosmetics stopped doing.
Daily use on face and bodyNo surfactants that strip your natural lipids. You leave the shower with comfortable skin.
Natural actives work with your skin to reduce the feeling of discomfort.
Respecting pH and the microbiome is the simplest way to bring calm back to reactive skin.
Formulated with sensitive skin in mind, so the rest of the family can use it too.

«The cosmetics of the future work with your biology, not against it.»
Over the last decade we learned something the industry ignored for decades: your skin's microbiota is essential to its health. And conventional cleansers strip it away, leaving your barrier without its natural defences.
At Heta Lab we don't follow trends. We study how skin really works and develop our products accordingly. That's all.
Your skin is home to a whole community of micro-organisms. When that community is balanced, it acts as your first line of defence. When it isn't, your skin lets you know.
A wide, diverse community of micro-organisms lives on your skin. It keeps harmful bacteria in check, helps regulate inflammation and strengthens your barrier.
Harsh soaps, an alkaline pH and sensitising fragrances weaken that community. Many skin problems — irritation, dryness, flare-ups — are linked to this imbalance.
Free of mineral oils, petroleum, silicones, propylene glycol, synthetic dyes, parabens and synthetic fragrance.
Genuinely gentle: no unnecessary aggression.
The solid format isn't an aesthetic trend: it's what makes the formula possible. No water as filler, no single-use plastic packaging and a smaller carbon footprint than any liquid cleanser. Less weight to ship, less waste to leave behind.
A solid bar, minimal packaging, no single-use bottles.
No filler water: less volume, less transport, fewer emissions.
We study how skin really works and build the soap accordingly. Now only one thing is missing: for you to try it.
