Innisfree Retinol Cica Blemish Ampoule is good.

The Innisfree Retinol Cica Blemish Ampoule is the ampoule I repurchased and am currently using.

To be honest, the price is a bit steep, so I recommend buying it during a sale. The regular price is a bit high, so I hesitated to buy it.

Some people mentioned that retinol stings, but whether it's because the concentration is low or it just suits me, I didn't really experience any stinging!

It spreads well, so it isn't too sticky, and I like that I can move on to the cream step right away.

If you use it consistently, it seems like it will be effective on marks as well.
