CeraVe Resurfacing Retinol Serum is a good product for those needing retinol in their skincare routine. It is specifically designed for those with uneven skin tone, post-acne scar marks, and large visible pores. I have been using it because I am concerned about my uneven skin tone and have recently become bothered by my pores. After using it for about a week and a half, I have noticed some improvement, so I plan to continue using it. Here are my findings: - Formulated specifically for those with post-acne marks, uneven skin tone, and visible pores - Helps refine, smooth, and improve skin texture without compromising the protective barrier - Non-comedogenic, paraben-free, and fragrance-free CeraVe resurfacing retinal serum should be applied 1x per day at night after washing skin. You may experience tingling /minor burning, I didn't but some people cite these sensations. You may choose to use it every other day if this occurs. I do like this product, and I would highly recommend it to anybody who is suffering from post acne scars specifically
