Salicylic Acid & Its Impact on Skincare

Vitamin C & Its Impact on Skincare
Vitamin C, also known as ascorbic acid is a water-soluble antioxidant that is crucial for your overall skin health. It can be naturally found in several vegetables and fruits, including spinach, oranges, and strawberries. It's an important factor for the production of collagen making it useful in anti-ageing formulations.
This buzz-worthy ingredient is available in different forms like L-ascorbic acid, magnesium ascorbyl phosphate, and ascorbyl palmitate to cater to various skin types and formulation needs.
It has been popular in the skincare industry for long due to its following advantages;
Acts on wrinkles and fine lines: Vitamin C has anti-ageing properties by increasing the skin's collagen production. Collagen holds the body tissues together. More collagen means fewer wrinkles and fine lines.
Enhances sun protection: Your skin needs to be protected from the sun in order to be protected from multiple upcoming concerns. Vitamin C-enriched sunscreen can mitigate UV-induced damage.

Has antioxidant properties: UV rays and pollution can cause free radicals which can lead to premature ageing. Vitamin C neutralises those free radicals and improves the skin's condition.
Heals wounds: Vitamin C can accelerate the natural repair process of the skin making it effective for wound healing. Its restorative properties can efficiently address minor cuts and scars.
Reduces hyperpigmentation: With disciplined use, vitamin C can aid your hyperpigmentation by triggering the regeneration of new cells into the skin.
