The "Tailami Jar Foundation Green 40ML" appears to be a foundation from the brand TAILAIMEI. Based on product descriptions and reviews, here's what the name "Green" likely signifies:

The "Green" in the Name:

The color "green" in the product name doesn't refer to the shade of the foundation itself. Instead, it refers to a specific type of product within the TAILAIMEI lineup, often associated with a "color-changing" or "color-adapting" feature. This is a common marketing strategy for this type of product. The foundation often appears white or a light, pastel shade when dispensed and then "self-adjusts" to match the user's skin tone as it is blended in.

Product Characteristics:

Brand: TAILAIMEI (sometimes stylized as TLM).

Product Type: Foundation makeup, often marketed as a BB or CC cream.

Color-Changing Technology: A key feature is the "shade-sensing beads," which are encapsulated pigments that release and adapt to your skin tone upon application.

Packaging: It comes in a jar, and the packaging itself may be green.

Net Weight: 40ml.

Effects: Descriptions highlight a range of benefits, including:

Lightweight and breathable.

Full coverage and concealing imperfections.

Moisturizing.

Long-lasting and waterproof.

SPF protection (some versions list SPF 15 or 30).

Ingredients: While a full, definitive list is not always available, some product pages mention ingredients like water, mineral oil, titanium dioxide, and lanolin. Another product, a "Green Tea Foundation" from the same brand, specifically lists green tea extract.

Target Audience: The product is marketed for all skin types and aims to provide a natural, flawless finish by adapting to various skin tones.

How to Use:

The application instructions are similar to other liquid foundations: apply a small amount to your face and blend it in with your fingers, a sponge, or a brush until it transforms and matches your skin. A little goes a long way, and using too much can result in a thick or unnatural-looking finish.
