My bum has dark spots and some area around them have dark skin and I also have some stretch marks .. I am always confident about my body but these things in my butt make me uncomfortable . Can you give me a solution please ?

The dark spots and dark skin around them may be due to hyperpigmentation. You can use a cream containing hydroquinone and tretinoin to lighten the dark spots. Apply it once at night for a few weeks. For the stretch marks, you can use a cream containing retinoids and hyaluronic acid to improve their appearance. Remember to use sunscreen during the day to protect your skin.
