Acyclovir is used topically to treat and prevent outbreaks of herpes simplex virus (HSV) and varicella-zoster virus (VZV) on the skin. It works by stopping the replication of the virus and reducing the severity of symptoms.

Acyclovir is recommended for individuals who have a history of recurrent herpes simplex virus (HSV) or varicella-zoster virus (VZV) outbreaks. It can also be used to prevent outbreaks in individuals who are at risk of developing them.

Acyclovir can be used on all skin types, however, it is important to consult with a dermatologist before use if you have sensitive skin or a history of allergic reactions.

Acyclovir should be applied as directed by a dermatologist or as directed on the product label. It is typically applied to the affected area of the skin several times a day. It is important to use it as directed and to not stop using it prematurely as it may cause the virus to become resistant to the medication. Acyclovir should be used in conjunction with other skincare products and should not be the only product used in a skincare routine.
