The essential step to take before applying nail polish is to buff the surface of the nails. Buffing helps to create a smoother and more even surface for the polish to adhere to, which can improve the overall look and longevity of the manicure. A well-buffed nail surface reduces the presence of ridges and imperfections, allowing the polish to apply more evenly and with better adherence.

Filing the nails is also an important part of nail preparation, but it primarily focuses on shaping the nails rather than ensuring a smooth surface for polish application. Applying lotion is typically done for moisturizing purposes, which might make the nails slightly oily and potentially hinder the polish from adhering properly. Soaking in water can also lead to moisture on the nails, which is not ideal for polish application, as it can affect the durability of the finish. Therefore, buffing is the most critical step in ensuring optimal nail polish application.
