Retinoids, or retinol, is an umbrella term for compounds that feature vitamin A. It has anti-ageing properties, helps unclog pores, and evens out your overall complexion.
So, what does retinol do? A retinol serum’s main purpose is to stimulate collagen production in the skin, which is naturally occurring but begins to decline in your mid-20s. This helps produce a natural, healthy glow and reduces the appearance of fine lines.
