The week before a wedding is not the time to try a new serum or a peel. Keep to the routine your skin already knows (sample advice).
Moisturise morning and night, wear sunscreen, and stop exfoliating three days before. If you have a facial booked, make it at least a week ahead.
On the morning, wash your face with your usual cleanser and come to the chair with nothing on it. We do the rest.
