oilyskinguru review for Collagen & Retinol Serum

This is actually a good retinol serum if you are a beginner. It is perfect if you have a sensitive skin like mine. It is lightweight, doesn't cause redness and irritation, it helps smoothen my texture and improves the overall appearance of my skin. I've been using this for a month and I can tell that this product actually works. It didn't cause me any breakouts or purging. I'm impressed and highly recommend this serum. It is a good quality product and quite affordable. ❤️
