When sourcing from distributors, prioritize formulations that balance pigmentation and hydration. Look for ingredients like Jojoba oil, Shea butter, and Vitamin E to prevent lip dryness, which is a common complaint with nude shades. For matte finishes, ensure the use of high-quality silica or kaolin clay rather than heavy waxes to maintain a lightweight feel. Always request a full INCI (International Nomenclature of Cosmetic Ingredients) list to verify the absence of harmful parabens or phthalates.
