Draw one lipstick swatch behind the contact point

1. Task and boundary

Plan a single cosmetic swatch on a resting forearm. The lipstick starts in light contact and moves only a short distance. Judge whether the colored trail follows the product, while the arm and the lipstick tube remain the same.

The intended result is a traceable deposit from a visible cosmetic applicator onto skin. A colored stripe that appears independently of contact does not show the application.

Match the product and starting color to the first frame. Keep a single swatch; this plan does not compare brands, add shade names or promise accurate color reproduction.

2. Authorized first frame

Use an original or authorized close view of a consenting adult forearm with intact skin. Show an uncapped lipstick held at a shallow angle, its short tip just touching the chosen start point, with enough clear skin for one short stroke.

3. Use the generator

Open the image-to-video generator, add your authorized first frame and paste the prompt. Check current options and cost before you submit; this page does not upload or submit on your behalf.

1. Choose a short exposed lipstick tip and a clear forearm area with the whole planned path in frame.
2. Start at light contact, so the clip does not need to solve both approach and application.
3. Request one straight stroke and a small lift without rotating the tube.
4. Inspect the leading contact point and the skin just ahead of it before judging the final swatch.

4. Prompt and timing

Fixed close view of the same consenting adult forearm and uncapped lipstick with a short exposed tip. Starting at the existing light contact, move the lipstick once in a short straight path along the forearm. Leave one continuous colored swatch only behind the tip where it touches. Preserve the tube, exposed tip length, hand grip and surrounding skin appearance. At the end of the stroke, lift the lipstick clear and stop; the swatch remains where it was drawn. No advance color, second stroke, whole-arm recoloring, melting tip or camera move.

5. Inspect the output

Inspect the actual clip from start to finish. Use pass, fail or not visible for each check; an attractive final frame does not prove the intervening motion.

• The lipstick maintains contact along one path before lifting at its end.
• The swatch grows behind the contact point and does not appear ahead of it.
• The tube, grip and exposed tip remain identifiable without extra fingers or a broken tip.
• After lift-off, one short swatch remains on the unchanged forearm.

6. Fix one failure

• If color appears early, shorten the path and specify that the tip is the only depositing point.
• If the lipstick bends or melts, keep the exposed portion short and reduce the travel.
• If the arm changes tone, fix the lighting and surrounding skin; reject the altered area rather than treating it as a match.

7. Ending and limits

Hold the lipstick clear of the arm while the full short swatch remains visible, including its start and end.

Generated color is not evidence of an actual shade, opacity, wear time or skin suitability. Product color comparisons require real approved imagery under controlled viewing conditions.

After inspecting a result, use the available result-save or download control. Keep the first frame, exact prompt and complete output together so that revisions can be compared.
