Activated Resorcinol™ Usage Concentration

Regarding your question about using Activated Resorcinol™ at a concentration of 2% in a face serum:

Based on the product information, Activated Resorcinol™ (4-Butyl Resorcinol) is a highly effective skin brightening agent. However, due to its high potency, it is strongly recommended not to exceed a concentration of 1% for leave-on products like serums or creams applied to the skin.

Using Activated Resorcinol™ at a concentration higher than the recommended limit, such as 2% for a face serum, can lead to potential side effects, primarily skin irritation. The manufacturer and formulation guidelines emphasize this limit to ensure safety and minimize the risk of adverse reactions.

Think of cosmetic active ingredients, especially highly pure and potent ones like Activated Resorcinol™, similarly to medication. Using more than the recommended dosage can cause harm or unwanted side effects, even if the substance is beneficial at the correct concentration.

Therefore, it is crucial to adhere to the recommended usage rate of not more than 1% for Activated Resorcinol™ in face serums to avoid potential skin irritation and ensure safe use.
