These are a few products I love and use on the job and before the job that are under $20.
Lush's Lemony Flutter Cuticle Butter:
Lush Lemony Flutter- great for hands and feet before a shoe modeling job. Or hand modeling jobs.
Revlon under eye concealer
I use this Revlon Colorstay concealer before my foundation or powder, let it sit for ten minutes first. I also use this when I travel for a whole face concealer.
Essie nail polish. This is a great brand for shoe models and hand models.
St Ives apricot scrub: about 6 bucks. For face, feet, and elbows, and back side.
Gillette After Shave Gel, until they come out with a gel like this for females I will be using my boyfriends after shave gel on my legs. It makes them very smooth after a shave and before leg modeling jobs.
