PRP (platelet-rich plasma) treatment

Q: I wanted to ask about PRP treatment and this is how it works: 

A sample of the patient's blood is drawn. The blood is then processed in a centrifuge to separate the platelets from other blood components. The concentrated platelet-rich plasma is then injected into the area needing treatment. The injected PRP stimulates the body's natural healing process by releasing growth factors and other proteins that promote tissue regeneration, collagen production, and inflammation reduction. 

Is this allowed? Because I have acne scars... and I don't know if its allowed or not. 

Assisting one's mother financially

Q: My mom divorced 15 years ago. My dad died 10 years ago but after his death since we were kids, mom decided to come and stay with us. She doesn't share any inheritance saying it's her right and her property and the rent which came from the property she favours the eldest brother and doesn't give us any of the part for 9 years. 

Now I am married and she's demanding me to take care of her monthly allowance which I simply denied because I am living separately and said that for 9 years you didn't give me my money that we got from tenants neither the share of the inheritance so why would I give you the allowance. Is it allowed for me to deny the request based on that or should I give her the allowance which I know will be given to my eldest brother who's 28 and physically good enough to earn by his own but he doesn't since he's spoiled by my mother and doesn't will to work or contribute to the house at all?
