1. Find a clear portrait photo: choose a high-definition photo taken from the front as the basis. This will ensure that you can better edit and adjust the details of the photos.

2. Use photo editing software: download and install a professional photo editing software, such as Adobe Photoshop. Open the photo you want to edit.

3. Peeling and whitening: Use the peeling and whitening function in the toolbar to remove the flaws and imperfections of the skin. Be careful not to overdo it, lest it look unnatural.

4. Adjust the facial features and contours: use the twisting tool or liquefaction tool to fine-tune the facial features and contours. You can stretch, compress, enlarge or shrink your face to make it more stereoscopic and beautiful.

5. Beautify your eyes: You can use the functions of eye magnification and brightness level to highlight the brightness and charm of your eyes. You can also use graffiti, filters and other tools to add some artistic effects and enhance the characteristics of photos.

6. Adjust the light and color: By adjusting the exposure, contrast, shadow and highlight, you can change the overall light and shadow effect of the photo. You can also use color balance or curve adjustment tools to adjust the color and tone of photos to make them more artistic.

7. Add filters and special effects: According to your personal preferences, you can add some filters and special effects to the photos to highlight the theme and personality. But be careful not to overuse it and keep the photos natural and true.
