What is an important consideration when applying makeup on sensitive skin?

When working with sensitive skin, using fragrance-free products is crucial because fragrances can often lead to irritation or allergic reactions. Sensitive skin is typically more reactive to various ingredients, and common allergens found in fragrances can exacerbate redness, itching, or other skin sensitivities. By opting for fragrance-free makeup products, an esthetician can help minimize the risk of adverse reactions and ensure a more comfortable experience for the client.

The other choices do not align with best practices for sensitive skin. Heavier foundations can clog pores and cause further irritation. Bright colors may contain pigments or additives that could irritate sensitive skin. Additionally, applying multiple layers of makeup can overload the skin, potentially leading to increased sensitivity or breakouts.
