Are Vitamin C derivatives less effective than L-ascorbic acid?Updated a year ago

Vitamin C derivatives offer stability advantages over pure L-ascorbic acid. This stability is crucial because skincare is a marathon, not a sprint. Consistency is key in skincare routines; it's about long-term benefits rather than short-term gains.

L-ascorbic acid, while potent, can be unstable and prone to degradation when exposed to air, light, or higher pH levels. This instability not only reduces its effectiveness over time but can also lead to potential irritation, particularly for sensitive skin types. 

On the other hand, Vitamin C derivatives are designed to be more stable, ensuring they maintain their efficacy throughout their shelf life.

Using stable Vitamin C derivatives consistently allows you to enjoy the benefits of antioxidant protection, collagen stimulation, and improved skin brightness without the need to scale back usage due to irritation.
