Observed side effects in research settings are generally mild and may include temporary nausea-related observations, flushing-related observations, headache-related observations, fatigue-related observations, administration-site irritation, pigmentation variability, pigmentation variability involving freckles or moles, and temporary appetite-related response variability depending on research amount, UV exposure, administration frequency, skin type, and individual physiological sensitivity
