Can botox cause dry skin?

Botox does not lead to dry skin. If you are experiencing dry skin, it would be best to follow up with a board certified dermatologist. He/she will be able to examine you in person and advise you accordingly. I hope this helps, and I wish you the best of luck. 

Botox is a wonderful product for facial injections.  Botox does not cause dry skin.  It sound like it is just a coincidence but I would ask my dermatologist during your next follow-up and perhaps they can suggest some treatments like oxygen facials or products like Vitamin C or serums to help with the facial dryness.

The dry skin you are experiencing is most likely not cause by the Botox injections. I recommend consulting a dermatologist to determine the cause of the dryness. 

It is well known that Botox can help improve acne.  This is due to the fact that it decreases sebum production.  Sebum is an oil that has been found to be excessive in acne patients.  It is possible that you might need that sebum production to maintain a healthy feel to your skin.  

Botox certainly does not cause dry skin. There are many causes for facial dry skin including seborrheic dermatitis, psoriasis or a contact dermatitis. Its a dermatologist injected the Botox then I would go back to see that doctor.

of course botox is also used to decrease sweating, but assuming all else is normal...the most likely cause for "dry skin" on the forehead is seborrheic dermatitis, a relative of dandruff...this can readily be treated with a moisturizer and/or some over-the-counter hydrocortisone for a week or so...then discontinue the cortisone till the need arises sometime in the future

No, Botox doesn't cause dry skin. Aging, sun, and environment are all factors in skin dryness. But Botox isn't. "This answer has been solicited without seeing this patient and
