Makeup bases, also known as primers, are designed to create a smooth surface on the skin, providing a canvas for makeup application. They can help to extend the wear of makeup, smooth out imperfections, and create a more even skin tone. Here are some features that are often associated with makeup bases:

• Hypoallergenic: A hypoallergenic product is formulated to minimize the risk of allergic reactions. It is typically free from common allergens and is suitable for individuals with sensitive skin.
• Magic Shield: The term "Magic Shield" suggests that the product may have some special properties, such as creating a barrier between the skin and makeup, or providing additional benefits beyond basic priming.
• SPF: Some makeup bases include sun protection factors (SPF) to help protect the skin from the sun's harmful UV rays. SPF is essential for preventing sun damage and premature aging.
• Size: The "50ml" indicates the volume of the product. It's a relatively common size for makeup bases, making it convenient for travel and daily use.
