Water (Aqua)

Water plays a very special skincare role as one of the ingredients in San Shield. Although water is commonly present in daily life, its importance in skincare products can easily be overlooked. However, water plays a crucial role in skincare, especially for moisturizing sensitive skin, where its functions are particularly special and important.

Water is a natural moisturizer, and the loss of water is the main cause of skin dryness. The water content in San Shield helps to keep the skin hydrated and enhances its moisturizing ability. Maintaining a balance of skin hydration is vital for sensitive skin, as dry skin is more susceptible to external irritants.

Furthermore, the water content in San Shield has a soothing and calming effect on the skin. Sensitive skin often experiences issues such as redness, itching, and irritation. Using water provides a cooling and soothing sensation, helping to alleviate these discomforts to a certain extent. Water molecules have small sizes and good penetration, allowing them to quickly penetrate the skin’s surface and provide immediate soothing effects.

Moreover, water also helps improve the absorption of other ingredients. Water’s solubility enables it to dissolve and stabilize other active ingredients in San Shield. As a result, when San Shield contains other ingredients with nourishing and repairing properties, the presence of water helps these ingredients penetrate deeper into the skin and exert their effectiveness.


It’s important to note that everyone’s reaction to these ingredients may vary. It is recommended to perform a patch test on a small area of skin before using any new product to ensure there are no adverse reactions.
