Several clinical studies have highlighted the efficacy of vitamin C in reducing wrinkles. For instance, one study revealed that consistent use of a vitamin C formulation for at least three months led to visible improvements in both fine and coarse wrinkles on the face and neck, while enhancing overall skin texture and appearance.

When paired with a broad-spectrum sunscreen, vitamin C also offers protection against harmful UV rays. Research indicates that combining vitamin C with other topical ingredients like ferulic acid and vitamin E can further reduce redness and shield the skin from long-term sun damage.

Moreover, vitamin C is known to diminish the appearance of dark spots by inhibiting pigment production in the skin.

In addition to its anti-aging benefits, topical vitamin C can aid in acne management due to its anti-inflammatory properties, which help regulate sebum production within the skin.
