My absolute favorite skin treatment. HG, if you want to call it that. I use Retin-A at night (have for nearly 40 years) and Perfectionist in the morning. It's all I need.
I like the actives in this...polypeptides, yeasties and algeas, hyaluronic acid, collagen, licorice and soy to lighten and brighten skin. I love the aesthetics of the serum...nice silicones for slip which make it great as a primer as others have mentioned. I like the way my skin feels, and like what the serum has done to my skin over time. I have never once broken out from it.
Over the years I've bought and used hundreds of products looking for the fountain of youth. I could have funded a country on what I've spent, using the most and least expensive stuff out there. The most effective turns out to be the simplest...a gentle cleanser like Cereve; very occasional exfoliation with a gentle scrub alternated with AHAs and/or BHAs...drugstore is fine; Retin-A; EL Perfectionist; and almost any moisturizer that works for my skintype (I like the Cereve line, Olay, Estee Lauder, some Clinique). Did I mention sunscreen? (Cereve or Neutrogena work just fine.)
What's important for me now is that the skincare I use be effective and proven by science (backed by progressive research), easy to acquire, gentle, and feel good on my skin...prbly in that order. Oh, and my skin needs to look its best without upset. And I can't get completely bored with a product...the results have to inspire me to keep using it.
I could prbly add vitC to my skincare routine, but don't worry about it. And I have not found a good eye cream. I'm using Algenist brand eye creams at the moment, which I find to be merely average. What I do lately is use a tiny bit of Retin-A under my eyes...which can be dangerous, cause I react so quickly there, but there's nothing like the wrinkle-fighting power of Retin-A.
I think what I'm trying to say is that benign neglect is the perfect way to handle my skin, as long as I have some heavy hitters in there working for me like Perfectionist. The rest I can let go.
