<s>[INST] I have dry flaking sort of brown pigmented dry patches in the right corner of my nose, and inbetween my breasts. I m not sure what the cause is but i ve had it all my life but recently they have been more pigmented and problematic than usual. Also there are sort of wrinkles in the dry pigmented area between my breasts (Most likely caused by wearing a bra and pushing the skin together.) the one on the corner of my nose is starting to spread down my smile lines and I m getting a bit worried. It is not very noticable but it feels rouger and flakes off when washed. What is the reason? Also I m 18 years of age and I ve been working with alot of acrylic paints recently? could that be the cause? [/INST] Hello. Thanks for writing to us at healthcaremagicI will keep a possibility of seborrheic dermatitis. Seborrheic dermatitis can present as itchy, flaky patches most commonly on the scalp; the patches can also develop at other sites such as the face and chest. All these areas are rich in sebaceous glands.The areas affected on the face are classically sides of nose, glabella, eyebrow area.Seborrheic dermatitis is a steroids responsive condition.I usually ask my patients to use a moderately potent topical steroid e.g fluticasone propionate 0.05%cream, twice daily.Topical steroids usually bring about remarkable improvement in seborrheic dermatitis in about 2 weeks when they can be substituted with topical immunomodulator e.g tacrolimus Or Pimecrolimus.Topical immmunomodulators may be used as maintenance therapy in seborrheic dermatitis since it is a recurrent condition.I would suggest that you visit a dermatologist in your region for a confirmatory diagnosis as well as appropriate prescription.Regards </s>
