Vitamin C for skin

The ideal percentage of vitamin C for topical use on skin can vary depending on the specific formulation and product. Generally, concentrations of vitamin C ranging from 8% to 20% are considered effective for skin care [2].

Lower concentrations, such as 8%, may be appropriate for individuals with more sensitive skin or for those who are new to using vitamin C in their skincare routine. Higher concentrations, may be more suitable for individuals with more resilient skin or those looking for more noticeable results.

It's important to note that vitamin C is a powerful antioxidant that can help protect the skin from environmental stressors, however, it can also cause irritation and sensitivity in some individuals, especially at higher concentrations. Your skin's individual needs will determine the right percentage for you, so it's always recommended to patch test any new skincare product and consult with a dermatologist before introducing new active ingredients into your routine.

Why pH as well as percentage matters

Vitamin C is notoriously unstable so the pH level of a skincare product is also important because it affects the stability and efficacy of this active ingredient. Vitamin C, also known as ascorbic acid, is an acidic molecule and works best in a low pH environment, typically between pH 3 and 4 [3]. 

If the pH of a vitamin C skincare product is too high, it can cause vitamin C to become unstable and degrade, reducing its effectiveness. This can also cause the product to become less potent over time, leading to decreased benefits for the skin.

On the other hand, if the pH of a vitamin C product is too low, it can cause skin irritation and sensitivity. This is because highly acidic products can disrupt the natural pH of the skin, leading to inflammation and redness.

Which means it's important to choose a vitamin C skincare product with an appropriate pH level to ensure that the active ingredient remains stable and effective while also being gentle on the skin. It's recommended to choose a product with a pH level between 3 and 4 for optimal efficacy and safety.

Why a good formulation is important

Finally, formulation is crucial in skincare because it determines the stability, efficacy, and safety of the product. The way ingredients are combined, the concentrations used, and the pH level all play a critical role in a product's ability to deliver intended benefits to the skin.

Here are some reasons why formulation is so important in skincare:

1. Stability: The right formulation can help to keep active ingredients stable and effective, ensuring that they deliver the intended benefits to the skin. For example, certain ingredients can become less effective or even inactive when exposed to air, light, or heat.
2. Efficacy: A well-formulated product can enhance the efficacy of active ingredients and ensure that they penetrate the skin and deliver the desired benefits. This can be achieved by using the right concentrations of active ingredients and by combining them with complementary ingredients that enhance their absorption.
3. Safety: Proper formulation is essential to ensure that skincare products are safe for use. This includes selecting clean ingredients, ensuring that the pH level is appropriate for the skin, and avoiding any potential irritants or allergens.
