According to the manufacturer's description, a positive result can be seen in as little as 4 to 6 weeks; the duration of use depends on the age and on the condition of the scar, spots or stretch marks. To correct stretch marks that have already formed, the cream is used for 3 months without a break. The card gives no studies or confirmation of the result.
General information (not a manufacturer's instruction): a cosmetic cream does not replace treatment and results differ between people; spots that change quickly are better shown to a doctor.
