How to apply ointments and creams to your vitiligo spots

vitiligo ointments

Many of the known treatments for vitiligo rely on daily ointment applications. But do we know how to properly apply the ointment and in what quantity ? Here are some guidelines on how much ointment to apply to your vitiligo spots.

The amount of steroid the patient should apply to a particular area can be determined by using the fingertip unit method. A fingertip unit is defined as the amount that can be squeezed from the fingertip to the first crease of the finger. The table below describes the number of fingertip units needed to cover specific areas of the body. One hand-size area (i.e., the area of one side of the hand) of skin requires 0.5 fingertip units or 0.25 g of steroid. The amount dispensed and applied should be considered carefully because too little steroid can lead to a poor response, and too much can increase side effects.

These indications can be used both when treating vitiligo with topical immunomodulators (Protopic, Elidel) and corticosteroids.

Please note that improper use of steroids can lead to skin atrophy, rosacea, erythema and infections so please consult your physician before starting a vitiligo treatment.
