Is Nimegen effective in clearing my skin of acne permanently? What are the chances of my acne relapsing?

I noticed that I tend to breakouts after holidays. Yes, weather and humidity changes can sometimes trigger breakouts. Stress/poor quality of sleep due to jet lag and time differences can also contribute. Speaking from personal experience here; I tend to break out much worse in Singapore than I did living in the UK. Went to national skin centre for consultation, and was given some watery creams and Cetaphil products to use. Hard to comment on what you were given, but from what you’ve described here, NSC doesn’t seem to have given you anything specifically for acne treatment.

Most doctors would definitely advise you NOT TO POP PIMPLES to prevent leaving a scar/bigger pores! Your pus-filled pimple holds oil, debris (dead skin cells etc), and acne-causing bacteria. Squeezing your pimple causes all that gunk to land inside other pores, introducing more bacteria, which can lead to more breakouts. You may also force the debris and bacteria even deeper into your skin where it can cause greater damage. Picking pimples also risks inadvertently damaging other skin tissues in the process, resulting in more inflammation, and increasing the risk of leaving a permanent scar.
