Which vitamin helps fade discoloration such as dark circles and bruises?

• A. Vitamin A
• B. Vitamin B
• C. Vitamin C
• D. Vitamin K

Answer: (D)

This question tests how vitamins relate to resolving skin discoloration from bruising and vascular changes. Vitamin K is the most relevant because it plays a key role in blood clotting and in strengthening capillary walls. By supporting the healing of small vessels and the breakdown of pooled blood in bruises, vitamin K helps reduce the lingering blue-purple tint and the appearance of dark circles that come from vascular leakage. In skincare, vitamin K is often used specifically to address under‑eye bruising and post‑procedure bruising for this reason.

Other vitamins have beneficial skin effects, like Vitamin C brightening the skin and supporting collagen, or Vitamin A promoting cell turnover, but they’re not as directly linked to resolving bruising and vascular discoloration as Vitamin K.
