The important boundary
A complexion product with an SPF claim is not a personalised protection plan. Regulations, directions, amount, exposure, and reapplication guidance vary. Follow the label and authoritative health guidance for your location.
- Check the current UV information from an authoritative local source.
- Follow application and reapplication directions on the product.
- Do not infer protection from finish, coverage, or price.
Plan the cosmetic layer
If products pill or separate, change one variable at a time and record the result. MakeupCast can remember that cosmetic outcome; it does not certify protection or diagnose a reaction.
Make it personal without guessing
Add an owned product and record a real outcome. MakeupCast can use that private history later without publishing it as market evidence.
