Start drinking lots of water immediately- the best habit is hydrate yourself from immediately waking up to before bed. Aim for a minimum of 3 litres. You’ll pee a lot initially but your body will get used to it after a few days.
I have a pint of water with half a lemon squeezed into it first thing every morning, it’s a miracle worker trust me.
Reduce caffeine intake to 1 cup in the mornings ideally
Start on WellWoman supplements or similar supplements, take one each day with your breakfast or lunch. I also take an additional high dose of vitamin C and D too.

If you wear make up or not ensure you are double cleansing at night then follow with a Glycolic toner (The Ordinary / Pixi Glow tonic). Leave a minute or two then continue with serums and moisturisers. Acid Exfoliation done gently will work wonders in 6 weeks. A hydrating moisturiser will plump up skin.
Decrease your alcohol intake, in fact cut it out altogether if it’s possible. Same for carbonated fizzy drinks to minimise bloating etc.
Stop smoking if you do, 6 weeks you won’t see too much of a difference other than you’ll smell better but the health benefits long term are worth it
Consider teeth whitening if they’re a little dull it’s a great anti aging trick
Go to bed early/ ensure you get good quality sleep to brighten those dull eyes.
Eye cream is a must too, no idea of your finances so invest in the best skincare within your budget. Don’t over complicate with too many lotions and potions otherwise you risk your skin breaking out.

I found cutting out sugar completely made my hair shine like glass, it was a shock but I did go very ott with it though not sustainable long term.
Have a good hair cut, not sure on your colour/greys situation but if it’s a thing obviously you’ll have that booked in for before the wedding, right?
