From product name

This product works by removing dirt and oil from the surface of the skin. It uses a combination of mild cleansing agents (candida bombicola/glucose/methyl rapeseedate ferment, diisostearyl malate, glyceryl behenate/eicosadioate, linolenic acid, polyglyceryl-10 behenate/eicosadioate, polyglyceryl-10 diisostearate, sorbeth-30 tetraoleate, stearoyl inulin) and should be able to cleanse the skin gently. Still keep in mind that any cleansing can disrupt the skin barrier, and most people do not need to cleanse their skin more than once per day.

What the product description says
“Cleanses blackheads and purifies the skin by providing pore care Improves skin tone by brightening any dark areas of the skin.”
Source: Lila Beauty

This product contains ingredients (pantothenic acid) that could help reduce blemishes and clogged pores in theory, but there is not enough evidence that they actually work.

Pantothenic acidEffect: MediumHelps attract water to the upper layer of the skin and may help reduce inflammation in skin~0.15–0.6%
NiacinamideUnder-dosedIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production~0.15–0.6%
