Detailed answer

Allergies to skincare products can cause skin irritation, rashes, redness, and itching. However, these reactions are localized and do not impact the cardiovascular system. Strokes are typically caused by factors such as blood clots, high blood pressure, or blockage of blood vessels in the brain. While severe allergic reactions can potentially lead to temporary low blood pressure or shortness of breath, they are not direct causes of strokes. It is essential to identify and avoid allergens in skincare products to prevent skin reactions, but strokes usually have other underlying causes that are unrelated to allergies.
