Yes, there are sunscreens specifically designed for sensitive skin that can be used on the face and bald head without causing pimples or rashes. Look for sunscreens that are labeled as "non-comedogenic," which means that they are less likely to clog pores and cause breakouts. You may also want to choose a sunscreen that is labeled as "fragrance-free" or "hypoallergenic" to reduce the risk of skin irritation.
When selecting a sunscreen for your face and bald head, it's important to choose a product with a broad-spectrum SPF of 30 or higher to provide protection against both UVA and UVB rays. You may also want to consider a physical sunscreen that contains zinc oxide or titanium dioxide, which are less likely to irritate sensitive skin compared to chemical sunscreens.
Before using a new sunscreen, it's a good idea to do a patch test on a small area of skin to check for any allergic reactions or irritation. Additionally, if you have a history of skin allergies or sensitive skin, it's always a good idea to consult with a dermatologist for personalized recommendations on sunscreen and skincare products.
