Take a good look in a magnifying mirror. Are your pores in need of a makeover? If so, consider booking an appointment with a dermatologist six to nine months before your bridal portrait takes place. Depending on the condition of your skin, a dermatologist might prescribe medication to treat acne and any other complexion problems you may have. It often takes at least six to 12 weeks for most medications and skin regimens to take effect, so keep this in mind when you schedule your bridal portrait.
