Start by eating well in the months leading up to your wedding: the better your diet, the clearer your skin. You may want to consider having intensive treatments like chemical peels and microdermabrasion, but plan carefully: you don’t want to trigger breakouts before your big day, nor do you want your skin to still be in recovery from whichever treatments you’ve chosen.
The night before your wedding, it’s recommended that you cleanse, exfoliate, and moisturise; and get a good night’s sleep. In the morning, cleanse again, apply a brightening serum (vitamin C serums are great) to even your skin tone, then apply some moisturiser with SPF to keep it hydrated and protected.
