The steroid may help a little but you should see a cosmetic dermatologist or facial plastic surgeon about using IPL or laser treatments for thid vascular discoloration.

Persistent dry lips may be lip eczema, which can be treated like skin eczema, using hydrocortisone cream plus Vaseline or Aquaphor to retain moisture. Sometimes, lipsticks or lip sunscreen chemicals cause an allergic reaction on the lips. Other times, a person is a primary lip-licker (it's her habit). DERMATOLOGIST can help. Desonide is stronger than hydrocortisone, meaning more caution in usage.
