Now that I'm past my mid-30s, just taking collagen isn't enough to keep my skin elasticity like it used to be.

I heard that PDRN promotes the production of collagen and elastin.

Are there any good ones?

I'm looking into InnerB PDRN from CJ Wellcare.

With 90% salmon extract, isn't that a pretty high content?

My skin is sensitive and delicate, so I'm wondering if it will suit me well and be gentle without any side effects. I'd appreciate some recommendations!
