For optimal results, a water-based vitamin C serum is generally preferred over a cream. This is because serums, being lighter and thinner, penetrate the skin more effectively than creams. Today.com and several dermatologists concur on this point. Allure.com
Why Serums Often Win
- Better Penetration: Serums' lightweight formulation allows for deeper absorption into the skin, maximizing vitamin C's benefits. Mario Badescu
- Higher Concentration: Serums typically contain a higher concentration of active ingredients, including vitamin C, leading to more potent results. Mario Badescu
When a Cream Might Be Suitable
While serums are generally recommended, a vitamin C cream can be beneficial for specific needs:
- Dry or Dehydrated Skin: The cream's moisturizing base provides hydration and supports the skin barrier. Foundationskincare.com This is especially useful for those with mature skin or those living in dry climates. SkinMumma.com
Layering for Maximum Benefit
Many skincare routines successfully combine both a serum and a cream. Applying a serum first allows for optimal absorption, followed by a cream to lock in hydration and provide additional benefits. Mario Badescu
In summary, while a cream might offer added moisturization, a water-based vitamin C serum generally provides superior penetration and delivery of vitamin C to the skin for better efficacy. Choosing the best option depends on your individual skin type and needs.
