Lip fillers, which are not Botox, will help a lot but if you don't want any procedures there's very little you can do. The effect of targeted creams etc is virtually nil.
Hyaluronic acid fillers. Fairly safe if you don't go over-board but need topping up every year. Google it with your post code and only get it done in a hospital environment, not a beauty salon.
I live in Scotland & regulated by GOV to the tune of £2000 to register and approx £1200 a year to remain open as a clinic, all nurses pay £120pa to NMC ....never mind insurance & sharps /clinical waste contracts!!
Gov demand wipable walls & floors with locked fridges & much more!
Beauticians dont have any of this hassel except insurance xxxx
