Feature 

vitamin C and collagen are common ingredients found in a wide range of products, from cleansers and serums to moisturizers and under-eye creams. Though they have their unique benefits when used alone, they complement each other when paired in the same routine.

Advantage 

 Vitamin C: also known as ascorbic acid, is a powerful antioxidant that can help brighten the skin, fade dark spots, and protect against free radical damage from UV rays and environmental pollutants. It can also stimulate collagen production, 

which is important for maintaining skin elasticity and firmness.
 Collagen: is a protein naturally found in the skin that provides structure and helps keep it plump and youthful. As we age, collagen production decreases, leading to wrinkles and sagging skin. Collagen serums aim to replenish and support the skin's collagen levels, potentially reducing the signs of aging.When combined in a serum, vitamin C and collagen work together to promote healthier, more radiant skin. These serums are often used as part of a skincare routine to target issues like fine 
lines, uneven skin tone
