How to Remove Redness from Skin in Photoshop

Excess redness in a subject’s skin is one of the most common issues in portrait photography, and it’s also one of the most straightforward to fix once you know how to isolate exactly the right red tones. This technique to remove redness from skin uses a Hue/Saturation adjustment layer targeted specifically at red, combined with a masked, brush-painted reveal, to correct redness across four portraits ranging from mild to severe.

Getting Started: Targeting Red with Hue/Saturation

The first step in every example is isolating the exact red tones causing the problem, rather than adjusting color across the whole image.

1. Add a Hue/Saturation Adjustment Layer

   Go to Layer > New Adjustment Layer > Hue/Saturation and click OK.

2. Switch from Master to Reds

   In the Properties panel, click the dropdown that says Master and change it to Reds, so only red tones are affected.

3. Sample the Red with the Eyedropper

   Use the eyedropper tool built into the panel to click directly on the reddest part of the subject’s skin, targeting that exact tone.

Why Push the Sliders to Extremes First

Temporarily dragging the Hue slider far to one side, and increasing Saturation, turns the affected color range bright and obvious — usually green or another unnatural color across the whole face. This is a deliberate diagnostic step: seeing exactly how much of the image is affected makes it possible to judge whether the selected color range is too broad, before dialing in the final subtle correction.

Narrowing the Color Range

4. Drag the Range Slider to Narrow the Selection

   Click the small slider beneath the color bar at the bottom of the panel and drag it inward to narrow exactly which reds are affected, watching the exaggerated preview color shrink to cover just the reddest areas.

How the Range Slider Works

Without narrowing the range, the adjustment affects a broad swath of red-adjacent tones across the entire face, changing far more than intended. Narrowing the range slider restricts the effect to only the specific reds sampled with the eyedropper, which is what keeps the correction targeted rather than global.

Shifting Hue, Lightness, and Saturation

With the range narrowed, the exaggerated preview colors get dialed back down to a natural, corrected result.

5. Reset Saturation to Zero

   Set the Saturation slider back to 0 to remove the exaggerated color used for the diagnostic preview.

6. Shift Hue Toward Orange or Tan

   Move the Hue slider a small amount to the right, shifting the targeted red toward a more orange, tan tone that matches natural skin.

7. Increase Lightness

   Move the Lightness slider to the right, since excess redness in skin is often also darker than the surrounding tone, and brightening it helps the correction read as natural.

Masking the Effect to Just the Red Areas

Applied globally, the correction reduces redness everywhere in the image, including places like the lips where that red tone is supposed to stay, so it needs to be masked to only the areas that actually need it.

8. Invert the Layer Mask

   Click the adjustment layer’s mask thumbnail and press Ctrl + I (Cmd + I on Mac) to invert it to solid black, hiding the effect everywhere.

9. Paint White to Reveal the Correction

   Press B for the Brush tool, set the foreground color to white, lower the brush’s Flow to around 20% for subtle control, and paint over the specific red areas of skin you want corrected — being careful to avoid the lips.

Why Invert the Mask Before Painting

Inverting the mask to black first means the correction starts completely hidden, and painting with white at a low flow builds the effect up gradually and only exactly where you brush. This is far more controllable than trying to erase an unwanted global effect after the fact, since it’s easier to add exactly what you need than to subtract exactly what you don’t.

Repeating on Subtler and More Extreme Examples

The same process scales down for milder redness and up for more severe cases, using the same steps each time with adjustments proportional to the problem.

10. Repeat the Full Process on a Milder Case

    Add a new Hue/Saturation layer, switch to Reds, sample and narrow the range, then use smaller Hue and Lightness shifts since the redness is less severe, and mask and paint in the same way.

11. Repeat on a More Extreme Case

    For a subject with more pronounced redness, use larger Lightness and Hue shifts to compensate, then invert the mask and paint the correction in across the face and neck as needed.

12. Repeat on a Final Subtle Case

    For the last, mildest example, use small Hue and Lightness increases with a touch of added Saturation, then mask and paint as before.

Cleaning Up Discoloration with the Spot Healing Brush

Skin redness is sometimes accompanied by small spots or discoloration that a Hue/Saturation shift alone won’t fully address.

13. Add a New Layer for Healing

    Create a new layer in the Layers panel and select the Spot Healing Brush tool, making sure Sample All Layers is checked in the options bar.

14. Click Away Remaining Spots

    Click directly on any remaining spots or discoloration that are still visible on the subject’s skin to remove them.

Common Mistakes to Avoid

Skipping the range-narrowing step is the most common issue, since it leaves the correction affecting a much broader swath of skin tone than intended. It’s also easy to forget to invert the layer mask before painting, which applies the correction everywhere at once, including places like the lips that should keep their natural red. And painting at full brush flow instead of a lower setting like 20% makes it harder to build the correction up gradually and control exactly how much reduction each area gets.

Why This Approach Works

The reason this correction holds up across four very different levels of redness is that every step isolates one specific variable before touching it. Switching from Master to Reds, then sampling with the eyedropper and narrowing the range slider, is what keeps the correction from spreading into skin tones that were never a problem in the first place — without that narrowing, the same Hue and Lightness shifts that fix the red patches would also shift perfectly normal skin elsewhere in the face.

Inverting the mask to black and painting the correction in with a low-flow white brush, rather than applying the adjustment globally, is what protects features like the lips that are supposed to stay red, while still letting the fix build up gradually and precisely wherever it’s actually needed. And reaching for the Spot Healing Brush only after the broader color correction is done addresses discoloration that a hue shift alone can’t reach, since a spot or blemish is a texture problem, not strictly a color one.

Final Thoughts

Excess redness is one of the most fixable problems in portrait retouching once you understand that the fix isn’t a single global slider — it’s isolating a specific color range, correcting it, and then masking that correction to exactly where it belongs. Once you’ve done this a few times, sampling the red, narrowing the range, shifting hue and lightness, and painting the result in with a masked brush becomes a fast, repeatable sequence you can apply to nearly any portrait with skin redness, regardless of how mild or severe the original problem is.
