Age Spots Or的意思|示意

Factors not associated with the rate of growth were the number of atypical moles or age spots or lier spots;

与增长速度并没有相关性的因素包括不典型痣，老年斑或者肝脏斑的数目；

On areas of the skin that have years of frequent and prolonged sun exposure, age spots appear when melanin becomes "clumped" or is produced in particularly high concentrations.

而对于长时间频繁遭受太阳暴晒的皮肤，黑色素便会“集群分布”或产生过多，此时就显示出老人斑。
