하이퍼 레티놀 EX 1.0 세럼

I haven't been using it for long, so I'm not sure about its effectiveness yet. But so far, I don't have any complaints.

Since it's my first time using this product, I've been applying a small amount. It doesn't seem to cause much irritation, which is good.

- I balance my skin's pH before application by using a low pH foam cleanser or toner.
- I use it in my evening skincare routine.

- I don't have any complaints yet. If I had to nitpick, I'd say the dropper could be improved.

- I love that it has a high retinol content and doesn't contain any ingredients that don't agree with my skin.
- Despite the high retinol concentration, it's not irritating thanks to the many stabilized ingredients.
- I was skeptical about its effectiveness since it wasn't irritating, but after daily use, I noticed gentle exfoliation of dead skin cells. Now I'm using it every other day!
- I was planning to switch to a pharmacy-grade vitamin A (retinol) product if this didn't work out, but I'm so pleased with it that I'll be sticking with this for a while.

There weren't any particular issues. If I had to pick something, maybe the scent? It has a medicinal smell. I suppose they intentionally didn't add fragrance...?

Certified full bottle - I'll stand it upside down to prove it! First impression: it applies moisturizing and absorbs well. After absorption, it's not sticky at all. Somehow, it leaves my skin feeling cool, not dry but hydrated. I've been consistently using retinol for anti-aging. Being curious, I've tried various products without settling, but thanks to my persistent retinol use, I think, I no longer stress about frequent milia or rough skin texture. It seems like those issues have improved without me even noticing.

The 20ml quantity feels a bit small. Also, the dropper's usability is slightly disappointing.

I noticed a slight improvement in pigmentation, and the next day after using it, my skin feels more elastic.

However, I did experience a slight tingling sensation during the first application. For beginners, it might be best to use this only in the evening. Also, it takes some time before you see noticeable results, so don't expect instant changes. The price point is a bit on the higher side, which might be a concern for some.

This product is known for its retinol content, which helps improve wrinkles and skin elasticity. I personally noticed some of my fine lines smoothing out after use. What I particularly loved was its lightweight, fluid texture that glides on the skin smoothly and absorbs quickly. It's also passed sensitivity tests, so I felt reassured using it without irritation. With consistent use, I found my complexion became more even.

I absolutely loved it! No skin irritation and no unpleasant scent

This is the real deal! After just a week of use, I can feel my pores shrinking

The quantity is a bit disappointing considering the price. It also has a noticeable scent.

This seems like a great introduction to retinol products. So far, I haven't experienced any tingling or irritation.

However, the volume is small, so I don't think it's particularly good value for money.

The hydration is great, and I've tried almost all products with retinol. This one is pretty good and reliable.

While the price is reasonable, it would be even better if they offered a larger size.

The retinol effect is definitely noticeable. My pores seem to have shrunk and my skin feels more firm and elastic.
