At DERMA E, our #1 priority is the safety and efficacy of our products. DERMA E products should not make you break out, however everyone is different and has unique responses to skincare. If you are concerned that a product might give you a reaction, we always suggest performing a patch test on the inner side of your elbow first. We stand by our products and our formulations, and choose to incorporate the best ingredients into our formulas in order to give you the most beautiful skin of your life! In fact, all of our products are formulated by a Doctor of Oriental Medicine and are shown to be effective yet gentle, even on sensitive skin.
