Retinol and vitamin C are the most studied chemicals for reversing signs of aging and providing a dewy glow to the skin.
Retinol is a derivative of vitamin A used in cosmetics to promote collagen production and cell turnover.
Vitamin C administered topically prevents aging and repairs skin damage. Vitamin C protects the skin from free radical damage.
This mixture of ingredients is ideal for delivering the intended preventive and anti-aging benefits; nevertheless, excessive use may cause skin irritation.
If you combine the two products, you may experience irritation. Try using vitamin C in the morning and retinol at night to decrease this.
Apply vitamin C serum to clean, dry skin in the morning, followed by moisturizer and SPF 30 or higher.
Apply retinol to clean, dry skin at night. Utilize a hyaluronic acid serum or a hydrating moisturizer if your skin is dry.
Choose a vitamin C product packaged in an opaque, airtight container, as light and air can oxidize or degrade its contents, rendering them ineffective or irritating.
Regarding retinol, begin with a low dose and select "encapsulated" or "time-released" retinol for sensitive skin, as these formulations are often less irritating.
