8Add Shimmer
I assume you are already consciously hydrating your skin every day and exfoliating it once a week. These things are crucial during summer.
Once you have prepared your skin like that you should try some glimmer to highlight your best features and your tan.
For your arms and legs, go with something light and apply it on your legs, collarbone and shoulders. For the face, pick a product with tiny sparkly particles, mix one part illuminator with two parts moisturizer in your palm and apply out from your nose.
