I think it depends on your skin condition, most say that you dont really need it until you are after 25 when the natural production of collagen declines in your skin but i think if your skin is dry and loose and you are not 25 yet then why not give it a go. I am 22 and recently started taking collagen tablets, I can tell my skin is better than before.作者: 12月之恋 时间: 2012-1-6 21:24:38
