Collagen Pills Won't Work
Collagen is an important part of one's skin — it provides structural support and elasticity. After age 20, people begin slowly losing their body's collagen supply each year.
Collagen supplements are often advertised as being able to do things like restore sagging skin and diminish wrinkles. Some research supports the idea that collagen supplements can be beneficial to one's skin and overall health, but the science isn't there.
When you consume collagen supplements, you can't actually target specific areas of your body and these products may not be absorbed by your body in a way that will make a visible or notable difference in your skin.'
