What is she wears a two way?

Based on the prompt, I believe you're asking about "two-way" makeup, which I am going to interpret as 2-Way Cake makeup. Here's some information:

2-Way Cake Makeup

2-Way Cake is a type of pressed powder foundation that can be applied in two ways:

Dry Application: Applied with a powder brush or sponge for light to medium coverage and a matte finish. It's ideal for touch-ups throughout the day and controlling shine. This application is similar to using a regular pressed powder.
Wet Application: Applied with a dampened sponge. Wetting the sponge allows for a more full-coverage, foundation-like finish. This is suitable for evening out skin tone and covering imperfections. Wet application also helps the product adhere better and last longer. This method can provide coverage similar to a foundation while still offering a powdered finish.

Key Features & Benefits:

Versatility: The main advantage is its dual-use. It functions both as a setting powder and a foundation.
Coverage: Offers buildable coverage from light to full, depending on the application method.
Finish: Typically provides a matte or semi-matte finish.
Convenience: It is a convenient and travel-friendly product, combining two makeup steps into one.
Oil Control: Often contains ingredients that help absorb excess oil and control shine.
Good for Different Skin Types: While generally suitable for all skin types, it's particularly popular for those with oily or combination skin because of its mattifying properties.

Application Tips:

Choosing the Right Shade: Select a shade that matches your skin tone.
Dry Application: Swirl a powder brush or sponge into the product and tap off any excess. Apply to the face in circular motions.
Wet Application: Lightly dampen a sponge (squeeze out excess water). Pick up a small amount of product and apply to the face, blending well.
Blending is Key: Ensure the product is well-blended, especially around the hairline and jawline.
Build Coverage Gradually: Start with a thin layer and build up coverage as needed.

Considerations:

Can Be Drying: The dry application, particularly with multiple layers, can be drying for some skin types. Moisturize well beforehand.
Hygiene: When using a wet sponge, ensure it is cleaned regularly to prevent bacterial growth.
Not Ideal for Very Dry Skin: Those with very dry skin might find 2-Way Cake too matte and potentially drying. Using a hydrating primer beforehand can help.
