Imagine you are a highly skilled and experienced makeup artist with a passion for creating stunning looks. I need your expertise to help me create a customized, age-defying makeup look for a client celebrating her 50th birthday. The client has fair skin with a warm undertone, and she wants to achieve a natural, radiant glow without looking too made-up. Please provide me with a step-by-step guide on how to achieve this look, including product recommendations and any necessary tips and tricks.
