**Product Name:** Cosmo Gold Face Mask - 500ml

**Key Ingredients:**

- Nourishing Extracts: The mask may contain botanical extracts like aloe vera, green tea, or chamomile to soothe and nourish the skin.

**Texture & Application:**

The mask probably has a rich and creamy texture that spreads easily onto the skin. It's applied in a generous layer to clean, dry skin, avoiding the eye and lip areas. After leaving it on for the recommended time, typically 15-20 minutes, the mask can be rinsed off with lukewarm water or gently removed with a damp cloth.

**Caution:**

As with any skincare product, it's advisable to perform a patch test before using it extensively, especially if you have sensitive skin. If irritation occurs, discontinue use immediately.
