Evolution history of IOPE’s retinol
Our research to stabilize retinol began in 1994. We have applied for 25 patents in Korea (registered 20) and 22 overseas patents (registered 14), published 10 SCI entries, presented at 17 international conferences, won six external awards, evaluated 500 skin-friendly ingredients, and reported 67 skin-friendliness evaluations. IOPE now proposes the 10th generation of its retinol.
Can cosmetics really smooth out wrinkles?
It is possible with IOPE Retinol Expert!

IOPE Retinol, proven by numerous customers and history
We have been together for a long time for young skin of women.
I've been using retinol since my late 20s, and even after I'm in my 50s, there are almost no fine lines.
I know people look at me and think I'm in my 40s.
I think the new retinol is even more amazing.
As soon as I applied it the first day, my skin felt tighter the next morning.

REAL User Reviews
I use it intensively on the nasolabial folds.
No, it feels like the pores are getting smaller?!
It has changed that makeup was caught in the wrinkles.
Especially the nasolabial folds! The wrinkles around the bridge of the nose are noticeably improved.
yur****I have nothing to say. This is my third purchase and I am using it.
You can apply it at night and look in the mirror in the morning to be satisfied.
It is the only product. Noticeable wrinkles around the eyes and nasolabial folds
I was worried because it disappeared and under my eyes went dark, but it was corrected
I think I will continue to repurchase. you should try it out
same. I hope everyone is as happy as me.
It's really a real recommendation.

IOPE RETINOL EXPERT
- 30's aclsq****
When I first started applying retinol, I was surprised every morning.
I feel like my skin is becoming luxurious day by day, so I look in the mirror first as soon as I open my eyes in the morning. I was greedy from the first time I applied it, so I applied it all over my face like an essence~^^
My skin was dry! pores! Figure 11 wrinkles?!
It was always stressful every time I looked in the mirror, but now others recognize me first~^^
It's been about 5 months since I applied retinol, but now I go with confidence as if my skin was originally good~^^
I bought it at 80,000 won and saw the effect of 8 million won~^^
Retinol Alabou~♥ - 40's jjun****
I have sensitive skin, so I haven't tried it yet, but I was concerned about the wrinkles on my neck, so I started it first.
It's been a week, is this a true story?
I can see with my own eyes that the deep wrinkles on the neck have softened.
It's no joke, it's a little red and itchy the first time I applied it, but after the second time it's okay. I'm going to try to get rid of the wrinkles on my neck. - 50s 0102353****
It was my first time using this product, but I was concerned about the wrinkles around the eyes and neck, but every time I use it, when I wake up in the morning, I feel really good because I feel sticky and firm on my face.
The next step is to purchase the product later. I want to recommend it to everyone around me.
Wrinkles separately, properly, with retinol.
You can change the future of wrinkles
