●Purchased product and purpose of purchase: I have sensitive skin, but I bought it because my pores were a concern. I also wanted to use it as a booster for the cosmetics I have, I'm writing this review so that people with sensitive skin like me don't regret it, so those with healthy skin who are thinking about buying the product don't have to read it, but those with sensitive skin who are hesitating can read it.

●Skin condition: Dehydrated and oily, but forehead + cheeks are very dry, oily only on the T-zone, pores on the nose and vertical pores on the butterfly zone.

●Feeling of use: I said 100 is for beginners, but please know that even 100 was irritating to people with thin skin like me. And since skin recovery varies from person to person, I don't recommend using 100 every day for people with sensitive skin. People with sensitive skin should use 100 only once a week, and replenish moisture three times more than usual. Thanks to the microneedles, my skin absorbs cosmetics better (I really praise Riddleshot's technology)

● Ingredients: Microneedles smaller than pores, cica effective ingredients

● Skin changes: It was definitely effective on pores. I felt that the pores in my butterfly zone were noticeably smaller, but even though I moisturized twice or three times more diligently than usual after use, my pores began to stretch, my cheeks started to redden, and itching occurred. I think this is because the cosmetic ingredients are oversupplied to my face. This is my problem with my weak skin rather than the product itself. If it weren't for this problem, I would have continued using it, but I have unhealthy skin, so it's a little disappointing.

But if I had to write about something good, I really liked how the effective ingredients in my retinol cream or essence were absorbed into my face.
