-Always use a fresh, new bottle of vitamin C serum, as the potency of the vitamin C decreases over time and with exposure to light and air.

Using a facial moisturizer is an effective way to hydrate the skin because it helps to seal in moisture and prevent it from evaporating. Moisturizers typically contain emollients, which can fill in the spaces between the skin cells and create a barrier on the surface of the skin. This barrier helps to lock in water, preventing it from evaporating and leaving the skin dry. Moisturizers also contain humectants, which can attract and hold water in the skin, helping to keep it hydrated.

Moisturizers are formulated to be lightweight and easily absorbed by the skin, making it easy to hydrate your skin throughout the day. They are also formulated specifically for the face, which is thinner and more delicate than the skin on the rest of the body.

Additionally, many facial moisturizers contain other ingredients such as antioxidants, sunscreen, and other skincare actives that can provide additional benefits for the skin. They can help to protect the skin from environmental damage, reduce the appearance of fine lines and wrinkles, and improve the overall health and appearance of your skin.

The skin barrier is the outermost layer of the skin that acts as a barrier to protect the body from external factors such as bacteria, viruses, and environmental pollutants. It also helps to retain moisture and prevent excessive water loss, which can lead to dry, irritated skin. The skin barrier is made up of dead skin cells, oils, and lipids that work together to create a protective barrier on the surface of the skin.
