Christmas Encounter Brighten Up Skincare Promotion Card

Create a professional Christmas skincare set promotion card with a vertical composition design, featuring a simple and high-end overall style. The background uses a soft gradient color, transitioning from ice white at the top to light pink at the bottom, creating a fresh and elegant atmosphere. At the upper center of the image, a set of high-end skincare gift boxes are meticulously arranged, with a frosted white packaging, embossed with delicate snowflake patterns and brand logo (Dior). The gift box is open, revealing three skincare bottles of different sizes inside, with simple and modern bottle designs and gold caps. Around the products, Christmas decorative elements are cleverly placed: several fresh pine branches, small golden bells, a few red berries, and scattered gift boxes, all props are carefully lit to present a high-end product photography texture. The top of the card uses a delicate and elegant font to write the Chinese title 'Christmas Encounter · Brighten Up'. Below the product in the middle, promotional information is marked in bold red font: 'Limited Gift Box 20% Off, Buy and Get 5 Sheet Mask'. At the bottom, there is text styled like a call-to-action button 'Buy Now Limited Quantity', and the validity period of the event 'December 15th-26th'. The overall design emphasizes the perfect combination of product texture and festival atmosphere. Aspect ratio 9:16
