While watching a YouTube video, I came across a know-how video that said horizontal wrinkles on the forehead can be reduced by softening and stretching the skin at the back of the head (around the ears), massaging the dent (the hollow at the back of the neck near the hairline) with your fingers, and then applying cream to the forehead and massaging in a stretching motion for about a minute, so I decided to give it a try with GA Cosmetics.
I think it takes daily effort. When I go to a chiropractor, the therapist first starts by softening the muscles and skin. I think daily care is important because my old sunburn marks have gradually faded with face wash and all-in-one gel.
From now on, I will try forehead massage during the day when I have free time. It seems to improve blood flow and somehow makes me more motivated!
