What the product description says
“Effaclar Medicated Gel Cleanser, 3.”
Source: Skinstore

This product works by removing dirt and oil from the surface of the skin. It uses a combination of mild cleansing agents (capryloyl glycine, carbomer, coco-betaine, decyl glucoside, hexylene glycol, peg-150 pentaerythrityl tetrastearate, peg-40 hydrogenated castor oil, peg-6 caprylic/capric glycerides, sodium laureth sulfate) 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.

Even though this formulation is mild, the following cleansing agents could trigger an irritation or allergy for some people: coco-betaine, decyl glucoside, sodium laureth sulfate

What the product description says
“Effaclar Dermatological Acne Treatment System”
From product name

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

Capryloyl salicylic acidKey activeEffect: Medium~0.2–0.4%
Glycolic acidKey activeEffect: MediumAn alpha-hydroxy acid (AHA) that helps to remove the dead skin cells on the surface of the skin reveling a more even, smoother complexation. It is also able to stimulate collagen production with long-term use. Could help to reduce pore congestion. It can be irritating to the skin. Apply sunscreen daily if using products with glycolic acid~0.2–0.4%
Zinc gluconateEffect: Low, below effective doseTypically used to stabilize the product formulations. It is a salt of a polyhydroxy acid (PHA) and in larger concentrations, can help shed the dead cells from the skin surface revealing smoother skin. It can help attract water to the upper layer of the skin. Might to be helpful against acne and clogged pores. Could be helpful in neutralizing free radicals, but solid research is missing. Due to the zinc content, might help calm down inflammation in skin~0.2–0.4%
Exfoliation
Not advertised by the brand · Glycolic acid, Capryloyl salicylic acid + 1 more
Works well

This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: capryloyl salicylic acid, glycolic acid.
