A At your age photoprotection is the number one most important thing. Moisturizer with at least SPF 30 plus a covering make-up does the best job. Ward off wrinkles, sun spots, and melasma this way. Definitely don't do fillers at this point I think it can actually age young people who do not need it. If you have no lines at rest on the forhead, then no need for Botox. You could start with very gentle nightly rejuvenation treatments such at human growth serum (Factor V). Maybe some light peels with a medical esthetician just to keep the pores health. Basically do very little!!!
