How to prevent the signs of skin aging when you reach your 30s
The best thing to do is to start taking care of your skin while you are still young. This article looks at the role that different types of collagen play in the body.
You will want to make sure that you are avoiding the sort of things that will cause your skin to age quicker too. Get the rest you need; sleep is when the body recovers. Don't smoke and limit the alcohol and caffeine you consume; all of these things will cause dehydration and your skin is where it will show up. Get the right kind of nutrients as it is important to also give your body what it needs on the inside.
You can consume collagen as a part of your diet, but this will result in a small portion of that collagen going to your skin. The body will take what it needs for supporting life and send that to the important places like the heart, lungs, and other internal organs first. To get the most from using collagen for your skin, use a topical application. This will deliver collagen straight to your skin which will mean that the effect is greater than only consuming it.
I would, and do, use both approaches to this to keep my skin looking and feeling younger. And it also benefits in supporting internal health also.
Something to keep in mind is that if you are taking silica to improve your skin and nails also, is that you must make sure you are drinking plenty of water. I consume 3 to 4 litres every day (with a pinch of mineral salt in it, not iodized salt) to make sure I'm putting back in to my body what is going out.
