[Anticipated Adverse Reactions and Side Effects]

The test product has been manufactured in compliance with applicable cosmetic laws and regulations, and the likelihood of adverse reactions occurring under normal conditions of use is expected to be low.

However, the possibility of adverse reactions, such as skin irritation (stinging, burning sensation, etc.), erythema, itching, and rash, cannot be completely ruled out depending on individual skin characteristics and sensitivity.

If an adverse reaction occurs during the clinical study, the principal investigator or study personnel will assess the severity of the adverse reaction and its relationship to the test product. If necessary, use of the test product will be discontinued, and appropriate medical measures will be taken.

In addition, if new information regarding the safety of the test product is identified or obtained during the clinical study, such information will be provided to the subjects or their legally authorized representatives without delay.
