Does applying vitamin C to the face increase skin elasticity?
Generally speaking, applying vitamin C to the face can increase skin elasticity to some extent, but it should be used in moderation. Detailed analysis is as follows:

Vitamin C is an essential cofactor for collagen synthesis and can promote the production of collagen within the skin. Collagen is a key component contributing to skin elasticity and firmness; as collagen levels increase, skin elasticity can improve. Additionally, vitamin C has strong antioxidant properties that help neutralize free radicals, protecting skin cells from damage caused by the external environment. This helps reduce oxidative damage to the skin, effectively delaying skin aging, and thereby indirectly improving skin elasticity and firmness.
If one excessively relies on vitamin C over a prolonged period without paying attention to overall skincare, such as cleansing, moisturizing, and sun protection, its effectiveness in improving skin elasticity may be limited. Therefore, when using vitamin C for skincare, it's important to use it in appropriate amounts.
In daily life, one should develop good living habits and maintain proper skin cleansing and care. Taking sun protection measures when going outdoors to avoid excessive ultraviolet radiation is more beneficial for maintaining skin elasticity.
