Detailed answer

Facial eczema is a sensitive skin condition that can be exacerbated by certain ingredients, including preservatives. Preservatives are commonly used in skincare products to prevent bacterial growth and prolong their shelf life. However, some preservatives, such as parabens and formaldehyde-releasing agents, can be potential irritants for eczema-prone skin. Opting for facial sunscreens without preservatives or those with natural preservatives may be a better choice to reduce the risk of irritation and flare-ups. Always read the ingredient list carefully and consider consulting with a dermatologist to find the most suitable sunscreen for your specific needs.
