IOPERetinol Expert 0.1% - Anti-Aging Serum with Pure Retinol, Reduce Wrinkles & Fine Lines, Pore Refining, Ideal for Retinol-Experienced User, Dermatologist Tested Korean Skincare, 1.01 fl.oz.

I'm used to a having retinol in my daily routine, so keep that in mind, because when I started my skin was more fragile. Sometimes products containing retinal don't do too much, and it seems as if there aren't any in the product at all. On days/weeks I don't use retinol, you can see a difference in how much more 'wrinkly' my face looks, and the weeks that I used this product, I didn't have the issue so the retinol content must be pretty good.

Pleasant, although the value for product is quite steep, even with how far a tube of targeting/eye cream tends to go. although isn't necessarily jsut for eye area so thus can disappear faster.. The ingredients had some red flags for me, like added fragrance but otherwise seemed pleasant to use. Can't say I've seen drastic results or anything to warrant repurchase yet but TBA

IOPE is a very well known and trusted beauty brand in South Korea, they make innovating products all the time, of great quality and care, this product is no exception, this is a light milky serum with a light scent, the bottle is sealed with a green plastic ring that you have to remove first then you twist the cap and twist back to open, the tub is long and thin making it easy to carry in your makeup bag or for travel. Instructions say to use it every other day for the first two weeks then every day starting on the third also to use at night because of the sensitivity to light. SO far I haven't seen a huge difference but I do see a difference specially on the lines by my mouth, the smile lines, this corrector should be using on the spots you want to target and not on the entire face.

The serum is great to travel with and has extremely high-quality ingredients. It feels very effective, and it helps brighten and moisturize the skin in a very positive manner - overall, a very high-quality product for travel.

unfortunately to strong for my sensitive skin to use regularly

Just starting to use, so can't speak to long term effects yet. This serum cream has a light, pleasant fragrance- scented products are not usually my preference but this one is nice- it smells vaguely floral and very expensive. No disturbances to my somewhat sensitive skin- have been applying to forehead and smile lines. It absorbs well and leaves a moisturized feeling, not drying. The container is very impressive- besides the brillent vilet color, it comes well sealed with a section that you twist and remove after the initial opening. After the extra ring is removed, it looks like the lid might be a 2-part dispenser but I think it's just an interesting design.

Two days of patch tests with no adverse effects1.01 fluid ounce tubeNo expiration date on the box or tubeI have been using this nighttime retinol serum for two weeks. I had a bit of an issue, figuring out how to dispense it. That was just a “me” issue though. It does not take much product as the instruction state only use it in areas of concern. For me, that is my eye area, that annoying T area on my forehead, and my starting to be more noticeable laugh lines. I have not had any concern with dryness, and I started using it every night right after my patch test. No visible changes seen, but I think it will take multiple tubes and months to see if it makes a difference.

This serum actually seems to work. Don’t get me wrong, this won’t make a 50 year old look like a 20 year old but I did notice very slight changes. I’m not sure that anyone else would really notice a difference and I really don’t either. I only know because I was documenting it. A subtle change for the better is nicer than a subtle change to the bad which is what I expect as I do get older. I appreciate even the tiny change because it’s better than going the other way. It only takes a little, and instructions say to only use it on problem areas, so it doesn’t take a whole lot. Luckily, I have had no adverse reaction, and my skin has shown a teeny tiny amount of improvement.
