DermShield technology works by temporarily suppressing neurogenic inflammation caused when a chemical peel is applied to the skin.  When a chemical peel is applied to the skin, a signal is sent to the type C nociceptor. A type C nociceptor in the skin detects the skin's PH level and temperature, similar to nerves that detect pain. Suppressing this neurogenic inflammation reduces any tingling, burning, itching, redness, and swelling, making treatments more accessible and pleasant.  This is why Noon Chemical Peel can use high concentrations of active ingredients such as 50% Glycolic Acid without triggering adverse side effects.
