What is 'Hirudoid' that I get from the dermatologist every season? What a 40-something housewife prone to redness from dryness found out

Reported by note · November 15 at 5:19 AM · Summary by Dew & Balm

A Japanese blogger who gets Hirudoid lotion prescribed for dry, easily reddened skin looked into what the drug contains and found drugstore products with the same active ingredient, heparinoid. The post lists the over-the-counter lotion's usage and warnings, including avoiding the area around the eyes and mucous membranes.

Background

Heparinoid is a heparin-like moisturizing ingredient used in Japan for dry skin. Many over-the-counter products in the US, such as lotions and creams, are marketed for dry skin, but their labels and regulation differ, so ingredient names alone do not mean the same product or dose.

Why it matters

It shows that the same active ingredient can appear under different brand names and in different strengths, so reading the full label matters.

What you can do

Check the active ingredient list and strength on any product you try, and follow the directions and warnings on the label. Ask your doctor or pharmacist before use if you bleed easily or take blood thinners.
