Learn more about PolybuteneEuphorbia Cerifera wax comes from a shrub in Northern Mexico. It is used to stabilize formulations and has emollient properties.
Emollients form a thin layer on top of skin to prevent water from evaporating, keeping skin and lips hydrated.
According to a manufacturer, this wax can range from a yellow/brown color to translucent.
Learn more about Euphorbia Cerifera WaxSilica is a mineral naturally found in our skin. It helps to thicken and smooth the texture of a product. It also acts as an agent for other ingredients by increasing the absorption of other ingredients into the skin.
Silica is often used for absorption and can help reduce shine when products are applied. Silica occurs in naturally in materials like clay and sandstone, and it can also be produced synthetically.
Silica is present naturally within the skin during collagen production and when reducing inflammation.

I used to love this mascara. It would lift my lashes and colour them dark pretty nicely but nothing so amazing. I did repurchase this twice but after each repurchase I realised it just wasn’t anything amazing especially for the price.
