Do not smudge blemishes away with Gaussian Blur. Duplicate the layer as a backup, cover each spot with the Patch tool, work at 200% zoom one spot at a time, then optionally sharpen with Unsharp Mask to bring the eyes back. Working slowly beats any one-click skin smoother.

1️⃣ Duplicate the layer (keep the original)

Before you edit anything, duplicate the original so you can always get back to the starting point.

  1. Open Online PS and import your photo (File → Open).
  2. In the Layers panel on the right, right-click the original layer Background → Duplicate Layer (or press Ctrl+J).
  3. Name the copy original_copy; from here on, all your retouching happens on that layer.

2️⃣ Pick the Patch Tool and zoom in

Use the Patch Tool to remove the spots. Zoom in first so you can work precisely.

  1. In the toolbar on the left, open the Spot Healing Brush Tool flyout and choose Patch Tool (the icon is two interlocking shapes).
  2. Hold Ctrl and scroll, or use the zoom buttons in the bottom right, to bring the blemished area up to 150%–300% (adjust to the size of the spots).

3️⃣ How to actually use the Patch Tool

The Patch Tool works on one idea: drag a selection onto a clean area and Photoshop blends the pixels for you. The details are what decide whether the result looks natural:

A. Match the selection to the size of the spot

Too large and you wipe out real detail along with the spot; too small and the edge leaves an obvious mark. What works:

  • For a spot about 5‑10 px across, draw an irregular 6‑12 px selection with the Lasso Tool.
  • If the spot is an odd shape, trace it in segments with the Polygonal Lasso.
B. Sample an area with a similar colour

When you drag the selection, land it on skin that matches both the colour and the lighting of the spot:

  • Dark spot, pick equally dark pixels; light spot, pick equally bright ones.
  • If there is a clear light gradient around it, stay on the same contour of illumination.
C. Keep strong dark/light contrasts out of the selection

When a spot sits on the boundary between light and shadow, pulling that boundary into the selection flattens the modelling. Do this instead:

  • Select the spot on its own — hugging its shape — rather than including the neighbouring edge.
  • If you must cross the boundary, select a small patch on each side and drag each one onto clean skin of the same tone.

After each patch, check the detail and refine it if needed.

4️⃣ Check your work with a quick before/after

In Photoshop you can toggle a layer on and off to judge each step:

  1. In the Layers panel, keep both original_copy and the retouch layer visible.
  2. Hold Alt (Option on Mac) and click the eye icon of the retouch layer to hide it temporarily and compare.
  3. If detail has gone missing, undo (Ctrl+Z) and select a better area.

Compare at 100% actual pixels — that is the only zoom level where you can see what each individual spot is doing.

5️⃣ Sharpen the eyes with Unsharp Mask (optional)

Once the spots are gone, you can bring the eyes back with Unsharp Mask (USM)†.

  1. Make sure the active layer is original_copy or a dedicated sharpen layer. (To stay non-destructive, add an empty layer, stamp the image onto it, then sharpen that.)
  2. Choose Filter → Sharpen → Unsharp Mask….
  3. Starting values (adjust to taste):
    • Amount: 80–120%
    • Radius: 0.5–1.0 px
    • Threshold: 0–2
  4. Click OK, then check the eyes at 200%. If highlights start to sparkle, lower Amount.

※ These values are only a starting point — skin tone and the amount of noise in the file change what works.

🛠️ More tips & things to watch

  • 🖌️ Name your layers — give each new layer a functional name (e.g. spot_fix_left_brow) so you can find it later.
  • 🔄 Save often — use Ctrl+S (or File → Save in the top left) to save the .psd, so a crash does not cost you the work.
  • 📏 Use guides — if the face is tilted, add horizontal or vertical guides via View → New Guide to keep things symmetrical.
  • 🌈 Colour correction — if the skin looks grey once the spots are gone, nudge it in Image → Adjustments → Levels or Curves.
  • ⚡ Shortcut summary:
    • V – Move tool (for dragging selections)
    • L – Lasso tool (drawing selections)
    • J – cycle between the healing and clone tools
    • Ctrl+J – duplicate layer
    • Ctrl+Z – undo

These are the details that make spot removal invisible. Practise them and the hand control comes quickly.
