My first attempt at an aged hand without any arthritic or vein prosthetics. What I’ve learned as a complete amateur:

• Liquid latex is EXTREMELY temperamental and needs to be layered quickly. Not recommended if you’re trying for aging accuracy unless you are a pro.
• Green Marble Sealer is fucking awesome for aging fx.
• Alcohol based makeup is awesome and even great for beginners.
• Cream based makeup SUUUUCKS but good for blending.
• Making a fist is the best way to create wrinkles on your hands as Green Marble cures.
