Makeup and skin
The better the skin is moisturized and cared for, the better it reflects light.
Your main task is to hydrate it in the morning before the shoot. Patches, masks, hyaluronic acid, light massage. I have reflective creams and light blush. But if you have favorite foundations, lipsticks, blushes, etc., bring them with you, we'll see on the spot.
The most important thing is your mascara.
Hairs
Clean hair, hair ties, a comb, and if available - a sea salt spray like Davines.
Nails
Well-groomed cuticles are a plus :)
Neutral or dark nail color if getting a manicure.
Avoid red and similar colors.
