Skin reactions can be unpredictable, checking the skin's tolerance to a brand-new item is necessary to identify potential allergic reactions. This is usually done before using any homemade soap for the very first time, whether it is store-bought or homemade. It is effortless to test your skin for a reaction before regular application by using a small bar of soap in a discreet and small area.
When trying new handmade soap or for the first time user, people with sensitive skin and people who tend to break out easily need to be more careful. Still, since everyone's skin is unique, and since tolerability differs significantly in between individual, a skin patch test is extremely recommended, no matter the skin type, to prevent possible skin reactions.
Lather up your handcrafted soap and try inside of your elbow or under your chin. Remove the patch immediately if you notice any signs of allergy such as rash, itching, redness, swelling, or burning feelings. If this occurs, wash the affected skin area with warm water, without scrubbing to prevent more inflammation. No reaction means that it should be fine to use the handmade soap. Discontinue use if a reaction occurs upon secondary applications.
