You can technically use serum without moisturizer, but it's generally recommended to use both for optimal skin health. While some serums are moisturizing, most only draw water into your skin, not seal it in. Using a moisturizer after serum helps to lock in the hydration and protect your skin from the elements.
Here's why using both serum and moisturizer is often better:
- Serums are specifically designed to address particular skincare concerns, like wrinkles, dark spots, or uneven skin tone. They are typically lightweight and easily absorbed by the skin.
- Moisturizers provide a protective barrier that helps to retain moisture and prevent dehydration. They can also help to soothe irritation and improve the overall appearance of your skin.
However, if you don't have dry skin and live in a humid climate, using only serum might be sufficient. Ultimately, the best approach depends on your individual skin type, concerns, and goals.
Remember: If you have oily skin, you might prefer to use a serum alone instead of applying a heavier moisturizer on top.
