Vitamin C is a powerful antioxidant known to aid in the skin's natural regeneration process. It helps repair damaged skin cells and neutralizes free radicals, resulting in brighter and more radiant skin. Additionally, it can boost collagen production, helping to reduce the appearance of fine lines and wrinkles.

Serums, including those with Vitamin C, are typically applied once or twice daily, but it's always best to follow the specific usage directions provided on the product or as advised by a skincare expert.

Many Vitamin C serums are designed to be gentle, but if you have sensitive skin, it's recommended to conduct a patch test or consult with a dermatologist before full application to avoid potential irritations.

Yes, after allowing the serum to fully absorb into the skin, you can apply sunscreen, makeup, or other skincare products. In fact, using sunscreen after a Vitamin C serum can provide enhanced protection against UV damage.

The time frame for visible results can vary based on individual skin types and concerns. However, consistent use over several weeks is often needed to notice significant changes. As always, it's important to be patient and continue using the product as directed for optimal results.
