I purchased the lightstim for wrinkles after some serious researching! The lighstim is the only device I could find that meets the requirement wavelengths and energy output etc. I’ve been using this product for about two week and am starting to see some results. Wrinkles were never a concern for me but it definitely helps with plumpness and the odd break out. I had a pimple on my chin that I popped and used the lightstim that night and it honestly almost disappeared before my very eyes! It’s also just a really relaxing experience and while having to hold it can be annoying be the end of the 30 mins, I highly recommend this product.
