What is a common method for applying a skin treatment mask?

Using a brush is a common method for applying a skin treatment mask because it allows for a smooth and even distribution of the product over the skin. Brushes can help in achieving a precise application, which is particularly important for ensuring that the mask covers all areas of the face uniformly without overloading any specific area. The bristles of a brush can also help in smoothing out the product, minimizing streaks, and making it easier to control the amount of product used, preventing wastage.

Moreover, brushes are also more hygienic compared to fingers, as they can reduce the risk of transferring oils and bacteria from the hands to the face. This is especially significant in a professional setting, such as a spa or salon, where maintaining cleanliness is crucial for client safety and satisfaction. Additionally, some treatment masks may have specific textures that are best applied with a brush for optimal results.

While other methods, such as using fingers or a sponge, can be effective in certain situations, they may not provide the same level of control and even application as a brush. Cotton balls may also not be suitable as they may absorb too much of the product or create an uneven layer.
