Yes, Panthenol can be used with Vitamin C in skincare formulations. Panthenol, also known as Provitamin B5, is a humectant that helps to attract and retain moisture in the skin. It has soothing and hydrating properties, making it a popular ingredient in moisturizers, serums, and other skincare products.

Vitamin C, on the other hand, is a potent antioxidant that helps to brighten the skin, reduce hyperpigmentation, and protect against environmental damage. It is commonly found in serums, creams, and other anti-aging products.

When used together, Panthenol and Vitamin C can complement each other's benefits and provide enhanced skincare benefits. Panthenol can help to hydrate and soothe the skin, while Vitamin C can provide antioxidant protection and brightening effects.

However, it's important to note that some skincare ingredients can interact with each other and potentially reduce their efficacy. For example, Vitamin C can be unstable and may degrade when exposed to certain ingredients, such as certain forms of Vitamin E or certain pH levels. Therefore, it's always a good idea to check the specific formulation or consult with a skincare professional to ensure compatibility and maximize the efficacy of both Panthenol and Vitamin C in your skincare routine.
