Here are my picks for bulletproof products that never fail:
Nurturing Force Blot Out Offensive: This is the best oil control product I have EVER used! Keeps oil at bay and makeup from slipping.
Mehron Skin Prep Pro: Liquid antiperspirant applied underneath makeup. Always apply as first step in skin prep!
Inglot AMC Gel Eyeliner in 77: The ultimate gel liner! Blackest black in existence, as well as the most waterproof/smudgeproof eyeliner I've ever used.
NARS Larger than Life Eyeliner in Via Venetto: These are great for personal use, great alternative to a gel/cream pot liner and stay the best on the waterline compared to other pencils.
Kryolan Dermacolor: All wax based foundations are waterproof when set properly, but this covers best in my opinion. Great range of colors and additional products in the entire line.
Premiere Products Inc. Blue Marble SELR Spray: This is the water-based version of the Green Marble SELR spray, used for special effects, meant for traditional beauty makeup. Blue Marble is not only affordable, but extremely effective in its sealing capabilities!
