Drug Overview

WASO is an acne calming treatment developed by SHISEIDO, a well-known brand based in Ginza, Tokyo. This product contains salicylic acid, which is a common ingredient used to help treat acne by unclogging pores and reducing inflammation. It is designed to target spots and promote clearer skin, making it a helpful option for those looking to manage acne effectively.

Uses

If you're dealing with acne, this medication is designed specifically to help treat this common skin condition. Acne can be frustrating, but with the right treatment, you can work towards clearer skin.

It's important to note that this medication does not have any known harmful effects on developing babies (teratogenic effects), making it a safer option for those who may be pregnant or planning to become pregnant.

Dosage and Administration

Before using this product, make sure to clean the skin thoroughly. You will need to apply a thin layer to the entire affected area. This can be done one to three times a day, depending on your needs and what your doctor recommends.

To avoid excessive drying of your skin, it’s best to start with just one application each day. If your skin tolerates it well, you can gradually increase to two or three times daily. However, if you notice any bothersome dryness or peeling, reduce your application to once a day or even every other day. Always listen to your skin and adjust as necessary.

What to Avoid

It's important to keep this medication out of reach of children to prevent accidental ingestion. If you or someone else swallows it, seek medical help immediately or contact a Poison Control Center for assistance.

Warnings and Precautions
