Detailed answer

Body oils should be avoided on sunburned skin on the bikini area after swimming. Sunburned skin is already damaged and sensitive, and applying body oils may further irritate the skin and delay the healing process. It is best to soothe sunburned skin with aloe vera gel or a cooling moisturizer specifically formulated for sunburn relief. These products can provide hydration and help reduce inflammation and pain associated with sunburn. If the sunburn is severe or accompanied by blisters, it is recommended to consult a healthcare professional for appropriate treatment.
