In this tutorial by Aaron Nace from Phlearn, learn how to effectively remove acne in Photoshop.
The process is divided into two steps: first, removing redness using Hue/Saturation to target specific red areas and make them look like normal skin tone. Second, removing blemishes with the Spot Healing Brush set to "Content Aware" and "Sample All Layers" to work non-destructively.
After clearing the blemishes, a bit of red is added back to the skin using a soft light blend mode for a natural look. This method ensures clear and realistic skin in your photos.
