Here is the solution

Traditional soap has a pH of 9–10 — far above the skin’s natural 4.5–5.5 range. Every wash chips away at your acid mantle, the chemical barrier that keeps skin hydrated, infection-free, and intact. A syndet bar is formulated to match your skin’s own pH, using mild synthetic surfactants instead of saponified fats. This guide explains the peer-reviewed science behind why syndet bars outperform traditional soap for sensitive, eczema-prone, and condition-affected skin — and how to identify a genuine one on a label.
