I have worsened under eye shadows and bags after using tretinoin 0.025%. Will this improve now I've stopped using it?

Thanks for you question and posting pictures.  Based on your age, I would like to try something completely non-invasive first.  The skin around and under the eye is very thin and we never suggest using a Retin A or Retinol in this area.  We suggest a physician grade topical from PCA Skin called Ideal Complex Eye Cream or Gel (retail $87).  It should be available at a physician's office in your area.  You can use it on your eye lid down to the lash line and under the eye up to the lash line.  You should see improvement within the week.  If that doesn't work, Pelleve is a great non-invasive treatment that is safe around your eyes.  Bulk RF heating causes some of the existing collagen to collapse, stimulating your body to generate new replacement collagen.  This is not a laser so it is safe for all skin types and can be done safely year round.  It feels like a warm rock massage.  Collagen building takes 90 to 120 days to see the results, so be patient.  We recommend 1 treatment per decade.  In your 30's, we would suggest a series of 3 treatments spaced 4 weeks apart.  You will continue to build collagen for up to 6 months after the last treatment.  Best of luck.
