Pros
I'm just trying a small amount at first, and it's not overly irritating, so it's been fine.
Cons
I haven't used it for long, so I'm not sure about the effects yet, but there aren't any downsides so far.

Pros
I like it because it has a high retinol content and doesn't contain ingredients that don't suit me. It's not irritating because it contains a lot of stabilized ingredients, despite the high retinol content. I was wondering if it was working on my skin since it's not irritating, but when I started using it daily, I noticed my skin gently peeling. So I'm using it every other day now! I was going to switch to a pharmacy-bought vitamin A (retinol) product if this one didn't work for me, but I'm really pleased with it, so I think I'll keep using this one for a while.
Cons
There are no disappointing aspects yet. If I had to pick one, it would be that the dropper is a bit disappointing.
Tip
Use a mild, slightly acidic foam cleanser or toner to balance your skin's pH before using the product. Use it in the evening.

Pros
This product is known to help with wrinkle improvement and skin elasticity due to its retinol ingredient, and I also felt that some of my fine lines were smoothed out after using it. In particular, the lightweight and watery formula applies gently on the skin and absorbs quickly, which I found pleasant. I was also pleased that it passed sensitivity tests, so it can be used without irritation, and with consistent use, my skin tone became more even.
Cons
However, there was a slight stinging sensation upon first use, and for beginners, it may be better to use it only in the evenings. Additionally, it takes some time for the effects to become noticeable, so drastic changes should not be expected. The relatively high price point may also be a concern for some.

Pros
It seems like a good introductory retinol product. There are no side effects like irritation, and it's not too harsh.
Cons
The amount seems a bit too little, so the cost-effectiveness is slightly lower.

Pros
The formula has a light yellow, thin consistency that flows quite easily, similar to a runny nasal discharge. It has good spreadability and absorption. While it doesn't contain 1% retinol, it does have a blend of 0.1% retinol, 0.6% bakuchiol, and 0.3% retinyl palmitate, making it a gentle introductory retinol product that can be gradually increased in usage. As someone with sensitive skin, I started with a very small amount and after a week-long adjustment period, I now use about three drops. I first cleanse my face, then apply a slightly acidic product or a booster serum to help absorption, followed by the retinol serum and a moisturizer. I haven't experienced any issues with this routine. The current formula feels light enough for the weather, but I think it may be too lightweight for the winter, so I'll likely switch to a richer, more emollient cream then. And for the summer, I may find it a bit heavy, so I plan to finish this bottle by April and repurchase in the fall.
Cons
Compared to other retinol products, I thought this was more affordable, but the amount is so small that it gets used up quickly. However, it's best to minimize air and light exposure for retinol products after opening, so using a smaller quantity like this may actually be better for preserving the quality of the cosmetic.

Pros
- Affordable price! Retinol skincare products are generally expensive, but this product has a good price-to-volume ratio. - Retinol is the most irritating ingredient, but this product mixes it with other derivatives to reduce the irritation of retinol while maintaining the effectiveness. - The amount seems appropriate to mitigate the risk of oxidation. If the quantity is too much, it may not be used up within 3-4 months, but this seems sufficient to use. - The retinol percentage is 0.1%, so I recommend this for retinol beginners with non-sensitive skin or those who have tried retinol derivatives before.
Cons
There are no significant downsides yet. The only slight drawback is that the retinol content is a bit lower, so the effects may be slightly less potent. However, this can be an advantage for those new to retinol.
Tip
It is recommended to store retinol in the refrigerator and use it within 3-4 months after opening. If used beyond that, the retinol active ingredients may oxidize or degrade, diminishing the benefits. For first-time users, it's important to check the retinol concentration and gradually increase usage while allowing your skin to adapt. This product contains 0.1% retinol combined with retinol derivatives, which can be a good starting point for stable adaptation. Also, retinol ampoules can be more irritating than expected, so it's best not to apply a large amount like a serum. Instead, dispense 2-3 drops into your palm and gently pat it into the skin. If you experience redness or discomfort, do not use the ampoule alone, but mix it with a cream or reduce the amount. For those who find retinol challenging, I recommend starting with retinoid derivatives first (e.g., retinoids).

Pros
It seems like a good starter product for retinol as it's not too harsh.
Cons
Since I have sensitive skin, I was getting breakouts when using it every other day, so now I only use it once a week.
Tip
You'll need to adjust the frequency based on your skin's condition.

Pros
It's retinol but it doesn't seem to hurt or irritate my skin. Usually when I use it, my skin peels, but this time it's fine.
Cons
It's been a week and some small bumps are coming up. :( I'm sad about it, but I'm sure I'll get used to it.
