Does the JENU help with penetration of other skincare creams like tretinoin/Retin A?
The JENU really doesn’t do much to facilitate transport. In my opinion, the main benefit is from the massage which stimulates the circulation in the skin and also helps with lymph flow in that sometimes sluggish under eye area. (Calvin – please link to eye cream section and Jenu (if we still have on the site).
It’s interesting that you ask this because there has been more research in the past few years on whether creating even temporary tiny holes in the skin with microneedling or lasers can facilitate repair if certain topicals are used immediately after the treatment (talking minutes here).
The answer seems to be that transport is facilitated, but only if done right away. In my opinion, this probably doesn’t make much difference really in your skin long term, since it’s just an occasional event. There’s beginning to be concern whether microneedling done too frequently may cause a number of new problems. Skin is a barrier for a reason and evolved that way over thousands of years!
Hope this helps, Dr. I
