The Perfect Combination of Vitamin C and Retinol: A Must-Follow Skincare Routine for Dull Skin

My complexion has been looking a bit dull lately, so I need to work on my skin whitening routine. I brighten my skin tone with a vitamin C ampoule in the morning and a retinol cream in the evening. This routine seems to be perfect for me. At first, I thought the retinol was a bit harsh, but once I got used to it, my skin texture became smoother and firmer. To simultaneously address freckles and maintain elasticity, I had to be diligent. Since the effort you put into your skin in your 40s is obvious, I never skip these two steps.
