Congratulations first of all and I would suggest you visit a qualified Aesthetic Dermatologist and get your skin checked before jumping to any treatments or laser for brightness. As you have almost 2 months left I guess so you need to make a proper treatment plan based on your present Skin condition. Also we need to check for any nutritional deficiencies that can make your skin look dull. Detailed consultation with proper treatment plan will definitely help you achieve your goal even within short span of time that you have.
Next Steps
Consult and discuss all the details to find out best treatment for you.
Health Tips
I would also suggest not to go for any aggressive or invasive treatments just before your wedding. As your skin needs time to recover. Wish you all the best for your treatment and for your Big Day. Regards , Dr Jeetendra Khatuja (Mumbai).
