The concern
What are acne, congestion and visible pores?
A pore can become blocked when oil and dead skin cells collect inside a hair follicle. A closed blockage can form a whitehead, while an open blockage can form a blackhead. Inflammation can then cause red spots, pustules, nodules or cysts. Pores can also look larger because of oil, surface build-up, sun damage or loss of support around the opening.
Common causes
What can cause acne and congestion?
Oil and dead skin cells
Excess oil and cells that do not shed normally can block a follicle and form a blackhead or whitehead.
Bacteria and inflammation
Bacteria that normally live on the skin can multiply inside a blocked follicle. The immune response can make the area red, swollen and painful.
Hormonal change
Hormonal changes can increase oil production. This is common during puberty, menstrual cycles, pregnancy and some medical conditions.
Products, pressure and friction
Oily products, tight equipment, masks and repeated rubbing can trap heat and oil or irritate acne-prone skin.
Genetics and medicines
Family history can increase acne risk. Some medicines can also cause or worsen acne-like breakouts.
A measured starting point
Start with a 3D skin test
For visible facial skin concerns, the Janus PRO scan gives your doctor objective images and measurements before a treatment plan is made.
It photographs the face with standard, cross-polarised, parallel-polarised and UV light. The system maps visible features such as pores, pigmentation, redness, texture and sebum. Your doctor reviews this information with your medical history and examination to make a more precise facial-skin recommendation. The scan supports the decision; it does not diagnose a condition or select a treatment automatically.
