Common questions
Where are my photos? On your phone only. Nothing is uploaded.
The plan changed after I edited my answers. That is by design: pregnancy, sensitivity, age and your concern change which nights get an active and at what strength. The reasons are listed under Treatments, Home care.
Numbers say "self-reported". Until the camera can measure, your answers set the numbers. They are labelled so nobody mistakes them for measurements.
Is this medical advice? No. SkinFormula is a wellbeing tool. See a doctor for anything that worries you.
