Acne is the most common skin condition people experience, affecting teenagers and adults alike. While it's rarely dangerous, it can affect comfort and confidence — and most acne responds well to the right approach, so there's no need to simply wait it out.

What causes acne?

Acne develops when hair follicles become blocked by oil (sebum) and dead skin cells. Bacteria, hormones, and inflammation all play a role. Common contributing factors include hormonal changes (puberty, menstrual cycles, and other shifts), genetics, certain products that block pores, and some medications. Diet and stress can influence acne for some people, though they're rarely the sole cause.

Common types

Acne can appear as blackheads and whiteheads (blocked pores), papules and pustules (the red or pus-filled spots most people picture), and deeper nodules or cysts, which are firmer, sometimes painful, and more likely to leave marks. Knowing the type helps guide the most suitable approach.

When to see a doctor

It's worth seeking care if acne is persistent, painful, leaving scars or marks, or affecting how you feel day to day. Early assessment can help prevent scarring and find an approach that works for your skin. Your iCollab family doctor or a walk-in physician can assess your skin and, where appropriate, coordinate a dermatology referral within the clinic.

How it's assessed at iCollab

Assessment starts with understanding your skin, history, and what you've already tried. Because dermatology is on the iCollab team, if specialist input is helpful, the referral path is short and your records stay connected. Any plan is discussed with you and tailored to your situation.
