Beauty & Makeup — Side-by-Side Results
Prompt
"A 22–28-year-old woman with shoulder-length wavy dark brown hair, dewy flawless skin, and minimal gold hoops sits at a small café table in a casual oversized knit sweater, looking just past the phone camera while tapping cream blush onto her cheeks with her fingers. On the table: an open compact, lip gloss, travel-size sunscreen, and an iced latte, arranged casually like a real TikTok “coffee + touch-up” moment. Natural window light with a soft ring-light glow from the phone, handheld selfie framing with slight motion blur for authenticity."

Flux Ultra 1.1 Strengths
- Exceptional photorealistic skin texture for close-up beauty shots (pores, glow, highlight falloff)
- Ultra-high detail that elevates product-and-face compositions (lip texture, lashes, brows, hairline)
- Premium, polished “campaign-ready” output for hero images and ads
- Strong realism for skincare narratives (before/after style concepts, routine visuals, clean studio lighting)
Seedream 4.5 Strengths
- Image-to-image editing for fast makeup iterations (swap lip color, adjust eyeliner shape, refine blush placement)
- Versatile style range for beauty content (editorial, clean beauty, glam, soft-focus, bold color stories)
- High-resolution output suited to multi-format social delivery (feed, stories, thumbnails) with consistent clarity
- Efficient for concept exploration when you need many variations of one look or routine
Verdict
If your priority is premium photoreal beauty imagery—especially tight face crops where complexion realism and micro-detail matter—Flux Ultra 1.1 is typically the stronger pick for hero shots and high-end skincare or makeup campaigns.
If your workflow depends on editing and iterating on an existing look (fine-tuning makeup placement, trying shade families, or adapting a base image into multiple styles), Seedream 4.5 is the more flexible choice. Since both cost 16 credits per image, the best value comes from matching the model to your production style: “final-frame realism” (Flux Ultra 1.1) vs “creative iteration and edits” (Seedream 4.5).
