Eliminate Dark Circles and Brighten Eyes in Photoshop

Eliminate Dark Circles and Brighten Eyes in Photoshop

Under-eye bags, wrinkles, and skin discoloration show up in every kind of photograph, but the fix isn’t to reshape someone’s face or hand the whole job over to AI. This technique to eliminate dark circles uses a soft, feathered selection and a simple Lighten-mode brush to reduce darkness under the eyes while keeping every person looking exactly like themselves, with a quick AI-assisted touch-up reserved only for small wrinkles.

Getting Started: Why AI Alone Falls Short

It’s tempting to select the under-eye area and let Generative Fill regenerate it automatically, but that approach tends to change more than intended.

1. Test a Generative Fill Selection First

   Make a selection around the under-eye area and generate new content with AI to see the result — it often reshapes the eye itself rather than simply lightening the skin beneath it.

Why AI-Only Fixes Can Look Wrong

The area under the eye is part of the eye’s own spherical shape poking out from under the eyelid, so regenerating that area with AI can subtly change the shape and tone of the eyes entirely, making someone look like a different person rather than a refreshed version of themselves. The goal here is only to lighten existing skin, never to redraw the underlying anatomy.

Making a Soft-Edged Selection

2. Select Under One Eye

   Press L for the Lasso tool and draw a loose selection around the area underneath one eye.

3. Add a Selection Under the Other Eye

   Hold Shift and draw a second selection under the other eye, adding it to the first.

Feathering with Quick Mask and Gaussian Blur

A hard-edged selection paints in an obviously defined patch, so the edge needs to be softened before any color goes on.

4. Enter Quick Mask Mode

   Press Q to enter Quick Mask mode, which lets you see your selection visually rather than guessing at it.

5. Apply a Gaussian Blur

   Go to Filter > Blur > Gaussian Blur and drag the slider while watching the preview, choosing an amount — around 10 to 25 pixels depending on the image’s resolution — that visibly softens the mask’s edge.

6. Exit Quick Mask Mode

   Press Q again to return to a normal, now feathered, selection.

Why Feather This Way Instead of Select > Modify > Feather

The standard Select > Modify > Feather command asks for a pixel amount with no visual preview of what that number actually produces. Feathering inside Quick Mask mode with a Gaussian Blur shows the exact softness of the selection edge in real time, so there’s no guessing at how many pixels is enough.

Painting in Lighter Tone

7. Set Brush Hardness to Zero

   Press B for the Brush tool, right-click on the canvas, and set Hardness all the way down to 0.

8. Sample a Lighter Skin Tone

   Hold Alt (Option on Mac) to activate the eyedropper and click a lighter area of skin nearby — not the darkest tone, the lighter one you want to paint toward.

9. Hide the Selection Edges

   Press Ctrl + H (Cmd + H) to hide the marching-ants selection outline (choosing Hide Extras if prompted) so it doesn’t distract you while painting; the selection itself stays fully active.

10. Create a New Layer and Set It to Lighten

    Add a new layer above the background, and change its blend mode from Normal to Lighten, so painting can only brighten pixels and never darken them.

11. Set Brush Flow to 10%

    With the Brush tool still active, set Flow to 10% in the options bar so color builds up gradually rather than applying all at once.

12. Paint In the Lighter Tone

    Click repeatedly over the selected under-eye area, letting the color build up gradually with each click until the darkness visibly reduces, without erasing all of the original shading.

Refining the Result

13. Adjust the Layer’s Opacity

    Lower the new layer’s Opacity if the lightening effect looks too strong, dialing it back until the result looks natural rather than obviously retouched.

14. Deselect

    Press Ctrl + D (Cmd + D) once you’re happy with the result.

Using AI Selectively for Wrinkles

Small wrinkles are one place where a quick pass with Generative Fill can help, used carefully and only on small, specific areas.

15. Select a Small Wrinkle Area

    Press L for the Lasso tool and select just the small area containing the wrinkle you want removed.

16. Generate a Fill for That Area

    Click Generative Fill type a single period in the prompt box, then click Generate to remove just that small detail. Review the results and pick one that looks natural.

Applying the Technique to Different Skin Tones

The same lighten-and-paint process works across different subjects and skin tones, as long as each area is sampled individually.

17. Repeat the Selection and Feather Process

    Lasso the under-eye area on a new subject, hold Shift to add a second selection if needed, then repeat the Quick Mask and Gaussian Blur feathering steps, adjusting the blur amount to suit that image’s resolution.

18. Sample and Paint on Each New Area

    Create a new Lighten-mode layer, hold Alt/Option to sample the correct nearby skin tone for that specific area, and paint it in with a low-flow brush just as before.

Sampling Color Separately for Each Area

When working across areas with noticeably different skin tones on the same photo, resample with Alt/Option separately for each one rather than reusing a single sampled color throughout. Painting a color sampled from one skin tone onto an area with a different tone produces an obvious, mismatched patch instead of a natural blend.

Common Mistakes to Avoid

Relying entirely on Generative Fill to remove under-eye bags is the biggest misstep, since it tends to reshape the eye rather than just lighten the skin beneath it. It’s also easy to skip feathering the selection, which leaves an obviously hard edge around the painted area, and to forget to reduce the layer’s opacity afterward — a result that looks right in the moment often reads as overdone a day later. Sampling one skin tone and painting it onto an area with a different tone is another common slip that produces a visibly mismatched patch.

Why This Approach Works

The core judgment call here is choosing reduction over replacement: lightening existing skin with a low-flow brush preserves the person’s actual features, while asking AI to regenerate the same area risks subtly reshaping the eye itself and producing someone who looks like a different person. Feathering the selection through Quick Mask and a visible Gaussian Blur, rather than guessing at a pixel value in a feather dialog, is what keeps the painted result from having an obvious, hard-edged boundary.

Setting the new layer to Lighten blend mode with a 10% flow brush means every click nudges the tone gradually rather than flooding the area with color all at once, which is exactly the kind of restraint that keeps a retouch looking natural instead of artificial. Reserving Generative Fill for genuinely small details, like an isolated wrinkle, rather than the whole under-eye area, uses AI for what it does well — filling in a tiny gap — without letting it make broader decisions about someone’s facial structure.

Final Thoughts

Dark circles, mild wrinkles, and uneven skin tone are extremely common in ordinary photos, and this technique handles all of them with nothing more exotic than a Lasso selection, a Gaussian-blurred Quick Mask, and a Lighten-mode brush at low flow. Keep the goal in mind at every step: reduce, don’t replace, and always dial the opacity back down after the fact, since a subtle result that still looks like the same person will hold up far better than a heavy-handed one.
