I just recently started to use ,
Beauty of Joseon
Revive Eye Serum with Ginseng + Retinal
I have done my fair share in the study of retinal and retinol. This is a Korean product which is wonderful. I love all of the ingredients in this, eye serum. I love that the retinal is a liposome. Which means it is encapsulated. The retinal in this eye serum is very gentle as it does not start to work until it reaches the, collagen layer. Very creamy gel like consistency, adsorbs easily, leaving my eye area moistened. When it states that it is 2%, because it is a Granactive Retinal, when you convert the math, it is actually 0.02%. Which perfect for the eye area.
The bright yellow color is due to the Retinal in the formula. True, Retinal cannot be bleached out.
If you are wanting to use a Retinal or Retinol product, I suggest researching a few different ones.
This one by, Beauty of Joseon is perfect.
