I was skeptical because it was cheap, but it was better than I expected for skin tone care.

I was a little worried since it was my first time using a undiluted niacinamide product, but Nano Recipe 20% Niacinamide Solution wasn't as difficult to use as I thought.

Since the price range was quite affordable, I tried it without high expectations, but the texture is light and absorbs quickly, so it was good to include in my daily routine.

Rather than applying a lot to my entire face from the start, I dispensed just one or two drops after toner and applied them first to areas where dullness was a concern.

After getting used to it for a few days, I tried mixing a little with lotion, and using it that way was less irritating and more comfortable. It wasn't too sticky after application, so it suited my evening routine better than my morning routine.

My skin tone didn't change overnight, but it was good to use for consistent care. I think it is a good product to choose for those who find expensive ampoules burdensome and want to start with pure niacinamide.
