How to use the panel: face selection, masks, retouching, frequency separation, comparison and saving your photo.

Purpose and preparation
Selective portrait retouching with editable Photoshop layers and masks: Skin Blemishes, Blackheads, Pigmentation, Skin Tone, Wrinkles, Eye Whites, Iris and Teeth. Preserving natural texture is the aim; always inspect the result.
Save the original document. Use an RGB document with 8 or 16 bits per channel. Wait for AI server ready. After a panel update, save documents and restart Photoshop.

Choose a face
Click Find Faces, then a thumbnail or Select. A blue border and Selected face N of M identify the active person. The panel selects that person's layer group without changing the photo position or zoom.
The first search stores a hidden source snapshot. Keep it and the metadata layers inside face groups. Repeating the search preserves matched groups and edited masks; newly found faces are appended. Do not resize the canvas after detection. Use a separate document copy for a new source.

Retouching workflow
1. Select a face and click Skin Mask.
2. Inspect at 100% image zoom. Select the layer-mask thumbnail in Photoshop to edit it.
3. Red means protected: NO processing. A black brush protects; a white brush allows processing. To return to the photo, disable the Photoshop mask display and select the layer's RGB thumbnail.
4. Click Process Face N, adjust strength, then select the next person.
Without a face list, Process All processes the whole photo using shared effects. Process Face N runs skin blemishes, blackheads, pigmentation, tone, eye whites, iris and teeth. Wrinkles and frequency separation are separate operations. Existing effects are retained; clicking again does not necessarily recalculate completed layers.

Sliders
The number above each slider updates while dragging and remains visible. Effect strength is 0–100%; radii are in pixels. A disabled slider usually means its effect layer does not exist or the region was not detected. In face mode, controls apply only to the selected person.

Wrinkles
Use 1. Detect Wrinkles, then Show Protection. Review the mask; use Black Brush — Protect for eyelids and folds to retain, or White Brush — Allow to expose an area. Show Photo returns to the photograph.
Click 2. Soften Wrinkles. Adjust Wrinkles and use Before / After to compare. After editing its mask, run Soften Wrinkles again.

Frequency separation
Create a skin mask first. High / Mid Radius ranges from 1–100 px; Mid / Low Radius from 2–300 px and must exceed the first radius. Defaults are 8 and 24 px; the step is 1 px. These are starting points, not universal settings.
Click Frequency Separation. Low Frequencies — Tone controls tone correction; Mid Frequencies — Detail controls middle-scale detail; High Frequencies — Texture controls selective repair of small dark texture defects. HIGH is not intended to remove all pores and may leave clean skin unchanged.
After changing radii, click Frequency Separation again to create a new separation. Check older groups' visibility. In face mode, separation uses the selected person's skin mask.

Compare, save and troubleshoot
Toggle an effect layer or the whole face group with Photoshop's eye icon. Inspect at 100% and at an overall view. Save PSD/PSB or layered TIFF; export JPEG as a separate flattened copy.
Check and protect moles, freckles, hair and natural folds. Higher strength does not necessarily improve quality.
If no change is visible, check the selected face, effect layer, mask, group visibility and strength. Do not switch documents or edit the photo during processing. Read any error message before retrying.
