#郑振镐教授# | 今日皮肤名言29

大家都知道维他命D是通过阳光在皮肤上生成的吗？
实际上为了生成每天所需的维他命D，并不需要照射很多紫外线B。
一般来说外出15分钟照射到的阳光就足够了。
但是世界卫生组织(WHO)建议我们要彻底隔绝紫外线，选择服用维他命D补充剂的形式来补充缺乏的维他命D。
所以担心维他命D不足的人从现在开始不要去晒太阳，而是服用维他命D补充剂比较好。

Been through some bad s*** I should be a sad b****, who would have thought it’d turn me to a savage. Sometimes life hits you like a truck, 17岁的雨季名副其实，生活在我最得意时迎头给了我一板砖, but it’s okay,
괜찮아 자 하나 둘 셋 하면 잊어
슬픈 기억 모두 지워
서로 손을 잡고 웃어
그래도 좋은 날이 앞으로 많기를
내 말을 믿는다면 하나 둘 셋
믿는다면 하나 둘 셋
一起数到三后，就忘记伤心的记忆吧，但愿好景常在…… https://t.cn/R2WxsQz
