(Purchased with my own money) IOPE Expert Retinol Super Bounce Serum

I purchased this product after seeing it recommended on a famous beauty YouTube channel, doing some research, and deciding it was good. Come to think of it, I recently bought some functional cosmetics, and I have three IOPE products. It seems the saying "the old is better than the new" is true. As everyone knows, the major benefits of retinol are improving fine lines and preventing wrinkles from forming. In addition, it offers anti-aging benefits such as pore reduction and improved pigmentation. I have used this product for a month and a half, and the biggest change I can feel with my fingertips is the improvement in my skin texture. My skin has become softer and smoother. Although 1% is a considerable amount, IOPE manufactured it stably, so I experienced no side effects from the retinol. I think this might be a good product to start with for those using retinol for the first time. If you are new to it, please remember that retinol should only be used at night, and it is best for pregnant women to avoid using it. Also, I recommend gradually increasing the frequency to once every 3-4 days, or sometimes every 2 days, to help you get used to it. I remember experiencing a lot of dead skin flaking on my face when I first used retinol from a different brand. I remember feeling stressed about it, even though it is a normal reaction to retinol rather than a side effect. They say IOPE Retinol minimizes such side effects, and since I didn't experience any particular side effects myself, I recommend it.

If you want to buy it a bit cheaper, I remember it being much cheaper when I purchased a set containing two at a duty-free shop. Just so you know.
