A minimalist cosmetic product poster design, featuring a single elegant product (e.g., a serum bottle or a cream jar) placed on a pristine, subtly textured surface. The atmosphere is refreshingly clean and serene, bathed in soft, ethereal pastel tones like mint green, baby blue, and gentle lavender. Focus on a smooth, almost translucent aesthetic to evoke trustworthiness and purity. Incorporate soft, diffused lighting with gentle highlights. There should be a subtle hint of natural elements like a dewdrop or a delicate pastel flower petal in the background, out of focus. Clean, sans-serif typography for hypothetical product name and slogan (e.g., "Pure Radiance", "Hydrate & Glow"). Aesthetic similar to high-end Korean skincare advertisements.
