According to their website Sero Vital is Human growth hormone (HGH). Here are some side effects (from WebMD). It has not been approved by the FDA for cosmetic uses.
Possible side effects of HGH use include:
nerve, muscle, or joint pain
swelling due to fluid in the body's tissues (edema)
carpal tunnel syndrome
numbness and tingling of the skin
high cholesterol levels
HGH can also increase the risk of diabetes and contribute to the growth of cancerous tumors.
I would get plenty of sleep, drink your water, and moisturize.
