- Following application to the skin, FRONTLINE Plus is absorbed into the skin and concentrates in the sebaceous
glands, spreading over the skin and coat via the pet's natural oils. - This topical defence kills parasites on contact, without the need for them to bite to be killed.
- Fipronil affects the central nervous system of parasites and causes them to become hyperactive. This means
fleas can be more visible when dying, which is a sign that the product is working.
