Publicité pour les soins de la peau de luxe Pastel

Create a vertical luxury skincare advertisement in a soft feminine pastel aesthetic, styled like a viral Instagram or TikTok beauty promo with no app UI. Show a single glass dropper serum bottle centered on a fluffy lavender-purple surface, photographed in ultra-realistic studio lighting with warm golden sunlight streaming from the upper left, soft shadows, glossy reflections, dreamy haze, and creamy bokeh in the background. The bottle label should read {argument name="brand name" default="ELEGANT SKINCARE"} and {argument name="product name" default="SERUM"}, with a pale pink-lilac translucent bottle and shiny rose-gold dropper cap. Surround the product with an elegant feminine vanity setup: 1 gold-framed round tabletop mirror on the left, 1 lit white candle in a glass jar on the right, 1 pearl necklace draped across the lower left foreground, and 4 clusters of white baby's breath flowers placed in the left foreground, left midground near the mirror, right foreground, and far right edge. Add cute hand-drawn doodle decorations in white and purple: curved arrows pointing toward the serum, sparkles, tiny hearts, short accent strokes, and small loops scattered around the composition. Include 2 paper note cards: one left of the bottle saying {argument name="left note text" default="My daily glow secret!"}, and one lower right saying {argument name="right note text" default="Feels amazing!"}; add 1 small round lavender sticker attached to the right note that says "MUST HAVE". Use large handwritten dark-purple headline text at the top reading {argument name="headline text" default="Glowy Skin In A Bottle"}, with a torn white tape-style strip underneath containing {argument name="tagline text" default="Nourish • Hydrate • Glow"}. Add smaller dark-purple copy to the upper right of the bottle reading "For Soft, Smooth & Glowing Skin", and at the bottom center repeat "For Soft, Smooth & Glowing Skin" with "Self care Everyday" beneath it in a lighter soft white tone. Keep the composition clean, premium, cozy, glossy, and highly aesthetic, with the serum as the clear focal point.
