Step 1

Open your image in photoshop and Duplicate your photo’s layer (Layer > Duplicate Layer).

Step 2

Add a Median Noise to the new layer (Filter > Noise > Median)

Step 3

Now, we’re going to Gaussian Blur the layer to get rid of the borders we got after adding the Median noice filter (Filter > Blur > Gaussian Blur

Step 4

Add a mask to this layer. Do this by clicking on your blur image and thin click on the third little icon at the botton on the later menu.

Step 5

Now clear the mask by selecting Black as foreground color, pressing (G) to select the Paint Bucket Tool and full the photo with black color. The new layer will be hidden and your image will go back to the orginal

Step 6

Now, we’re gonna start removing the wrinkles. Choose the White color as a foreground color, the press (B) to select the brush tool. Then, edit the brush settings to your needs, just make sure the hardness is set to 0%

- Start brushing the skin smoothly without touching the details (Hair, Eyes, Lips)

Good luck --- this was a rush job, take your time, enlarge the image if you need to.
