Erythcalm SC is a natural active ingredient that can quickly relieve skin redness, repair skin barriers, and brighten skin tone. Its active ingredients (mainly lignans and terpenes) are extracted from Trifolium repens, which can effectively inhibit the activation of ADRB2, HRH1, TRPV1, and EDNRA, thereby reducing the release of vasodilator CGRP and alleviating skin redness caused by stimulation.
