What is a skin fix API?

A skin fix API is a web service that automatically retouches skin in photos using AI. You send an image, and the API removes blemishes, evens skin tone, smooths texture, and polishes AI-generated artifacts — while preserving identity, pores, freckles, and natural features. Used by AI headshot platforms, beauty apps, photographers, and ecommerce brands to deliver professional-grade skin retouching at scale.

How does AI skin retouching work?

The API automatically detects skin regions and applies targeted corrections: blemish removal, color evening, texture smoothing, and artifact polishing. Unlike consumer filters that apply a uniform effect to the whole face, the pipeline treats skin as structure — preserving pores, fine features, and natural variation so the result looks like real healthy skin, not an airbrushed mask.

Does it preserve identity?

Yes. Skin Fix changes surface issues on skin without altering facial structure, features, or proportions. Freckles, moles, and scars that are part of someone's identity are preserved by default — only blemishes, acne, uneven tone, and harsh texture are corrected. The person in the output is unmistakably the same person.

Does it work on all skin tones and ethnicities?

Yes. Skin Fix is trained on diverse skin tones, ethnicities, and natural skin variation for consistent quality across fair to deep skin. Corrections target surface issues (blemishes, acne, unevenness) without altering underlying skin tone, natural pigmentation, or ethnic features — no single beauty standard is baked into the output.

Does it preserve freckles, tattoos, birthmarks, and skin conditions?

Yes. Freckles, moles, tattoos, vitiligo, rosacea, birthmarks, port-wine stains, and significant scars are treated as identity features and preserved by default. Skin Fix corrects only surface-level issues — blemishes, acne, temporary redness, uneven lighting, and AI-generation artifacts. If your use case requires a different treatment (e.g., fading tattoos for specific content workflows), contact us.

Does it work on AI-generated headshots?

Yes. Skin Fix is especially well-suited for polishing AI-generated headshots before delivery. Generation models sometimes produce glitchy skin — plastic textures, unnatural shines, waxy patches — and Skin Fix corrects these artifacts without regenerating the image. Used by headshot platforms as a delivery-polish step.

Can I control the intensity of retouching?

The API targets natural, professional-grade retouching by default — the kind of polish a skilled retoucher would do, not an aggressive beauty filter. We don't expose per-effect intensity sliders in the default endpoint; contact us if your use case needs more granular control.

What happens if the API can't detect skin in my image?

The API returns a structured response for every call. If no skin regions are detected (e.g., a photo without faces, a heavily stylized source, or a cartoon-like AI output), you'll get an error code with a descriptive message so your integration can handle the case — retry with a different input, fall back, or surface to the user. For transient infrastructure issues, internal retries are included in the price.

How much does the skin fix API cost?

$0.12 per image with simple fixed pricing. Sign up and get $10 in free GPU credits to try it out. Contact us for volume pricing on bulk workloads.

Can I process images in bulk?

Yes. Batch endpoints with async webhook delivery. Process thousands of images per job — ideal for wedding shoots, headshot delivery pipelines, and catalog retouching workflows.

How fast is the skin fix API?

Typical response times are under 3 seconds for standard resolution images. Built for production workloads with consistent latency at scale.

What image formats are supported?

JPEG, PNG, and WebP. Output format depends on the solution.

Typical response times are under 5 seconds for standard resolution images.

Skin Fix is how we ship AI headshots that look photographed, not generated. Raw AI outputs can have strange skin texture — occasional plastic look, glitchy pores, uneven tones — and we run every delivered headshot through Skin Fix to polish these before the user sees them. It's the difference between 'AI headshot' and 'professional headshot.'
