Are suggested skincare products safe for breastfeeding with hyperpigmentation?

You may have a fungus infection in your groin. It may result in scratching and irritation of the affected areas. I suggest you go to a dermatologist who can diagnose and cure your disease.
 

Itching on cheeks, hands, and back could be due to: 
- Dry skin
- Allergic reaction 
- Eczema or psoriasis 
- Bug bites or hives 
- Medication side effect. 

Try moisturizing, avoiding irritants, and OTC antihistamines. If symptoms persist, see a dermatologist. 

The most common reasons behind this are allergies and skin irritation. You should pay attention to the products you use because they should not contain any harmful ingredients. To fight against this problem, moisturize well and avoid using soaps and chemicals that are too harsh.

Staphylococcus aureus often leads to skin infections, boils, and even more serious problems such as bloodstream infections. It's caused by bacteria that may be hard to completely remove from the body. If the usual treatments like augmentin were ineffective in getting rid of the infection, vancomycin recommended by your friend is worth considering. Vancomycin is an antibiotic usually used as a last resort for persistent staph infections, especially those that do not respond to other antibiotics. When using vancomycin, it is important to follow your doctor's advice on dosage and treatment duration. 

It seems like you’ve got post-inflammatory hyperpigmentation after popping your zits. These can result in dark marks on your face. To fade them away, consider trying out products that contain vitamin C, niacinamide, or kojic acid as ingredients. Sun protection is key since UV rays can worsen the appearance of these spots. Also, remember not to irritate your skin further to avoid more dark spots.

You might have a condition called ichthyosis vulgaris, where the skin becomes dry and itchy because it doesn't shed properly. To manage this, it's important to keep your skin moisturized with non-irritating, fragrance-free lotions. Taking warm, not hot, showers with mild soap can also help. Don’t forget to drink plenty of water, as it helps nourish your skin from the inside.

Acne occurs when you have these red spots on your face caused by your skin producing too much oil. It's super common, especially during the teenage years. To help, you can use a face wash with benzoyl peroxide or salicylic acid. These can clear up your skin by unclogging your pores.
