Q-1：我是极度过敏性肌肤，对很多化妆保养品都会过敏，请问龙优娃产品容易造成皮肤过敏吗? I have extremely sensitive skin, and I am allergic to many cosmetics and maintenance products. Can LONGYUVA products cause any skin reactions?

A-1：产品研发过程中已特别将一般常见过敏成分自配方中移除，且经数十位过敏肤质者亲身测试后并无过敏性反应，虽然引起皮肤过敏的可能性极低，但还是请使用者初次使用前先少量(一二滴)涂抹在洗净的手背上简单测试一日，如果没有引起过敏反应，那合理推断龙优娃产品对您应该不会诱发皮肤过敏。  In product development, those known common allergy-causing ingredients have been eliminated from the formula, and there have been no allergic reactions reported after being tested by dozens of volunteers who are prone to allergic reactions. Although the possibility of having skin allergy is low, it is advised to apply a small amount (one or two drops) on the back of hand the day before using this product for the first time.
