It is not just Cyspera, but any medication can have an adverse reaction to your skin, so it is a case-by-case basis.
For this reason, we ask our patients to continue using this product under regular medical examinations by a doctor. It is known that this product is less likely to cause allergic reactions than other skin whitening products, but in rare cases, it can cause severe redness, itching, dryness, etc. If this occurs, please discontinue use and consult with our doctor.
For those with sensitive skin, the manufacturer recommends applying the product for 5 minutes for the first week, followed by a maximum of 10 minutes for the rest of the treatment period. During maintenance treatments, the product should be applied for up to 10 minutes, twice a week, with the use of an effective moisturizer at least twice a day.
