Illuderma carries a 60-day money-back guarantee from the date of purchase.
The guarantee runs for 60 days from purchase and covers dissatisfaction with your results or your overall experience. Given that tone-related results typically take 2 to 3 months, many customers choose the 3 or 6-bottle package partly to align with this guarantee window.
Contact the official store directly with your order number, within the 60-day window. Some guarantee programmes require unused or empty bottles to be returned; confirm what applies to your order before shipping anything back.
