What I Looked for Before Buying
When I first considered the Numbuzin No 5 Goodbye Blemish Serum, I wanted a serum that could help with blemishes, dark spots, and uneven skin tone without irritating my skin. I usually pay attention to ingredients, texture, skin type suitability, and whether the product feels gentle enough for daily use. For me, a good blemish serum should not only target acne marks but also support overall skin clarity.
My First Impressions of the Serum

For me, that balance is important because harsh products often make my skin more sensitive.
How I Would Use It in My Routine
I found that this type of serum works best when used after cleansing and toning, but before moisturizer. In my experience, consistency matters more than anything else with blemish treatments. I would use it once or twice a day depending on how my skin feels, and I would always follow it with sunscreen in the morning to protect my skin from further darkening.
