Not All Vitamin C Is Created Equal
While Vitamin C is widely recognized for its benefits, not all forms perform the same. Many formulas rely on L-ascorbic acid—a form that can be unstable and prone to oxidation when exposed to air and light.
This can impact both performance and overall user experience.

Vitamin C Skincare FAQs
What does Vitamin C do for your skin?
Vitamin C is a powerful antioxidant that helps protect the skin from environmental stressors such as UV exposure and pollution. It also helps improve the appearance of brightness, uneven tone, and fine lines while supporting collagen for firmer-looking skin over time.
Why is Vitamin C important in a daily skincare routine?
Skin is exposed to oxidative stress every day, which can accelerate visible signs of aging. Incorporating Vitamin C into your morning routine helps defend against these environmental aggressors while supporting overall skin health, making it a foundational step in maintaining long-term skin performance.
When should I use Vitamin C—morning or night?
Vitamin C is best used in the morning to help defend the skin against daily environmental exposure. It can also be used in the evening to correct the damage from the day, but morning application is especially beneficial when paired with sunscreen for enhanced protection.
Can Vitamin C be used with other skincare ingredients like retinol?
Yes. Vitamin C pairs well with many commonly used skincare ingredients, including sunscreen, hyaluronic acid, peptides—and even retinol.
While some forms of Vitamin C, such as L-ascorbic acid, are often recommended to be used separately from retinol due to their low pH and potential for irritation, C+ Correcting Complex 30%™ is formulated with THD Ascorbate. This highly stable form of Vitamin C is designed for improved compatibility within a routine.
Because of its formulation and pH profile, it can be used alongside retinol products—allowing for a more streamlined approach to supporting antioxidant protection and skin renewal without the need to separate application.
Is Vitamin C suitable for all skin types?
Vitamin C is generally suitable for most skin types, including those concerned with uneven tone, or visible signs of aging. Choosing a stable, well-formulated version can help improve tolerability and overall performance.
Why does Vitamin C oxidize, and what does that mean?
Certain forms of Vitamin C, such as L-ascorbic acid, can be unstable and may oxidize when exposed to air, water, and light. Oxidation can reduce effectiveness and may cause the formula to change color over time. Stable forms and protective packaging can help maintain performance.
What makes THD Ascorbate different from other forms of Vitamin C?
THD Ascorbate is a highly stable, lipid-soluble form of Vitamin C designed to penetrate more effectively into the skin. It is known for its improved stability compared to traditional forms and is formulated to deliver antioxidant benefits with enhanced tolerability.
How long does it take to see results from Vitamin C?
Some improvements in skin radiance can be seen relatively quickly, while more visible changes in tone, firmness, and the appearance of fine lines typically develop with consistent use over time. Daily application is key to achieving and maintaining results.
Can Vitamin C help with dark spots and uneven skin tone?
Vitamin C helps improve the appearance of discoloration and uneven skin tone by supporting a brighter, more uniform-looking complexion. With consistent use, it can help skin appear brighter and balanced.
Do I still need sunscreen if I use Vitamin C?
Yes. You always need sunscreen no matter what! Sunscreen is imperative for better skin health protection. This is a non-negotiable. While Vitamin C helps provide antioxidant protection, it does not replace SPF. Using Vitamin C in the morning alongside a broad-spectrum sunscreen helps provide a more comprehensive defense against environmental stressors.
