Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that itchy, scaly redness around her lips can be due to
Perioral Dermatitis..
Gatorade does not seems to be the cause for this rather can be due to causes like:
It can be caused due to disturbances in microbial flora over the skin, bacterial infection,nasal and topical steroids, flouridated toothpastes, harsh chemical cosmetics, poor facial hygiene, hormonal imbalances etc..
I would suggest you to
consult a Dermatologist and get evaluated and he can do a thorough clinical evaluation and advise you to apply topically ointments containing Doxycycline,
Metronidazole..
You can also be advised oral intake of
erythromycin..
Ointments containing Azaelic acid,
Pimecrolimus etc can help..
Avoid any skin cosmetic or steroid ointments..
Avoid excess sun exposure, use gel based sunscreen lotion..
Hope this information helps..
Thanks and regards.
