[ LASER PERFUSION IMAGING ]

This is your scalp on HotFlux®.

HotFlux® is included to support scalp microcirculation — which is also why some users notice that signature warm or tingly scalp sensation.

Why does it tingle?

The warmth is not random. It comes from a deliberate ingredient choice in the Bio-Pilixin® Activation Serum formula.

01

It starts with HotFlux®.

HotFlux® is Vanillyl Butyl Ether, a controlled warming cosmetic ingredient used to create the serum’s recognisable warm scalp sensation.

A mild warm or tingly sensation may be noticeable for some users.
02

Same family as capsaicin.

Vanillyl Butyl Ether belongs to the same chemical family as capsaicin — the chemistry associated with chilli peppers — without describing HotFlux® as being derived from capsaicin.

Think related warming chemistry, not literal chilli on your scalp.
03

TRPV1 senses the warmth.

HotFlux® interacts with TRPV1 receptors in the skin. That interaction is associated with the local warming sensation and helps explain why the tingle can appear soon after application.

More sensation does not necessarily mean better results.
04

Included to support microcirculation.

HotFlux® is included to support scalp microcirculation. The tingle is the sensory part of that formulation story — not a warning sign to ignore if irritation becomes strong or persistent.

Discontinue use if you experience notable redness, tenderness or persistent discomfort.
