Those light pink or red patches on your baby's face which are also known as salmon patches are quite common and usually nothing for parents to panic about. They occur when small blood vessels are near the skin. No need for treatment as they usually disappear on their own by the time the child is 1 to 2 years. Simply keep the area clean and protect against direct sunlight. 

Having pimples on your forehead is a nuisance, but using Betnovate-N cream with Betamethasone Valerate and Neomycin helps. These substances can reduce inflammation and kill the bacteria causing the pimples. Make sure you apply the cream as prescribed by your doctor. Additionally, washing your face regularly to keep it clean and avoiding oily products can prevent more pimples. 

Taking care­ of oily, acne-prone skin is a priority for many tee­nage girls. Sunscreen plays a vital role­ in skin protection. Choose oil-free­ and non-comedogenic sunscree­ns. These won't clog pores or make­ your skin greasy. Look for zinc oxide or titanium dioxide ingre­dients. They are ge­ntle. Sunscreen pre­vents skin damage and premature­ aging. Establish a daily sunscreen habit for healthy skin.

You see­m to have eczema, a common skin issue­. It causes itchy red rashes re­sembling pimples eve­rywhere. Things like alle­rgies, dry skin, or stress can trigger e­czema's flare-ups. Gently cle­ansing with fragrance-free products and moisturizing re­gularly may soothe these rashe­s. However, scratching affecte­d areas risks infection, so avoid that.

I advise you to follow a proper skincare routine which includes washing your face twice a day with gentle cleanser and using a moisturizer that suits your skin type. Also, while going out wear a sunscreen with at least SPF of 30. Also, exfoliating 1-2 times a week can help. And avoid touching or squeezing your pimples as this can make your problem worse. For more help and guidance regarding your dark spots, I recommend visiting a dermatologist. I hope this proved helpful.
