Top 5 Skin Myths We Hear in Clinic (And the Truth Behind Them)

With so much skincare advice online, it’s easy to feel confused. In clinic, we hear the same myths again and again – and they can actually slow down your progress. Here are five common beliefs our team at Thorold Medical Aesthetics & Skin Care gently corrects all the time.

Myth 1: “If it stings, it’s working.”

A mild tingle with some active products can be normal, but strong burning, itching or pain is a red flag. Discomfort doesn’t equal effectiveness – it often means irritation or barrier damage.
The truth: The best results usually come from consistent, comfortable routines, not constant burning and peeling.

Myth 2: “I have oily skin, so I don’t need moisturiser.”

Oily or acne-prone skin can still be dehydrated. Skipping moisturiser often makes things worse, as the skin produces even more oil to compensate.
The truth: Lightweight, non-comedogenic moisturisers help balance oil production and support a healthy barrier.

Myth 3: “I only need SPF in summer or on sunny days.”

UV rays penetrate clouds and windows, and they’re one of the main causes of premature ageing and pigmentation.
The truth: Daily SPF is essential all year round – especially if you’re having treatments like peels, microneedling or laser.

Myth 4: “Scrubbing hard will get rid of my acne faster.”

Harsh scrubs and over-cleansing can inflame the skin, spread bacteria and trigger more breakouts.
The truth: Gentle cleansing, the right actives (like salicylic acid or retinoids) and, when needed, medical support will take you much further.

Myth 5: “Professional treatments are only for severe problems.”

Many people think clinics are only for “extreme” cases. In reality, we treat everything from mild congestion and first fine lines to advanced conditions.
The truth: Early, preventative care often means you need less intervention later.
