Detailed answer

Preservatives are added to skincare products to prevent the growth of harmful bacteria and prolong their shelf life. While some people may develop allergic reactions to certain preservatives, most allergic reactions in skincare products are triggered by other ingredients such as fragrances or botanical extracts. If you have specific allergies, it is important to read the ingredient list carefully and avoid products that contain the allergens you are sensitive to. Additionally, choosing products that are labeled 'hypoallergenic' or 'fragrance-free' can help minimize the risk of allergic reactions. If you have severe allergies or are uncertain about which products to use, consulting with a dermatologist or allergist can provide personalized guidance.
