Whats your budget??? You can go for an intense peel but your looking at anywhere from £300-£800. This sort of peel strips the top layers of the skin to reveal fresh new undamaged skin underneath. The down time on these is about a week. It will take a further month to see the full results, which during this time you must ensure you use decent skincare and a high SPF.
Your the same age as me so unless you have really deep wrinkles I doubt you will need anything as intense as a peel.
There are glycolic facials such as nimue or MD Formulations that work by removing the top layers of skin but dont go as deep as medical peels. you have no down time but you should still use the skincare and SPF. With Glycolic facials you need to use the creams a fortnight prior to a facial so your skin gets used to the glycolic acid.
Theres also Danne Montague King as well which helps to clear up spots and lift the skin to tighten any sagging, close pores, and remove dead cells. These facials are fantastic if you suffer from a lot of black heads.
Without seeing your skin and going off it sounding similar to mine, I wouod recommend starting a course of Microdermabrasion Facials and start using MD Formulations. Have a Microdermabrasion Facial first then start using the glycolic creams, a fortnight later have a peel and alternate every two weeks. You should see a visible difference in four weeks to your skin without down time.
It does all depend on budget, your also limited by the time you have which we only have 7 weeks now until christmas, so you need something that will give you fast results.
Hope this helps
