BURN
What it is, how to calm it down and how to stop it coming back.
Razor burn is skin irritation caused by shaving. It usually shows up as redness, stinging and tenderness, and most often comes from a worn blade, too much pressure, not enough lubrication or shaving too quickly. It typically settles within a few days. To soothe it, rinse with cool water, apply an alcohol-free moisturiser and avoid shaving the area until it has calmed down.
What Causes Razor Burn?
It drags and tugs instead of cutting cleanly, which irritates the skin.
Pressing down scrapes at the skin rather than cutting the hair.
Shaving dry, or with water alone, leaves the blade nothing to glide on.
Going against the grain or over the same area again and again adds friction.
Fast, uneven strokes lead to more pressure and more passes.
Skin that is dry or easily irritated reacts more to friction.
How to Soothe Razor Burn Fast

Action: Splash for 30 seconds or so.Dab gently with a clean towel rather than rubbing.
Action: No rubbing.Use a fragrance-free, alcohol-free moisturiser or a plain aloe vera gel.

Is Your Razor the Problem?
If you get razor burn every time you shave, the technique tips above may not be enough. Your razor could be working against you. Check for these signs:
- Your blade is more than a week or two old.
- You press down to get a close shave.
- You need several passes over the same spot.
- The razor head feels stiff and doesn’t follow your jawline or neck.
- You skip shaving cream because the razor “glides well enough”.

When to See a Pharmacist or GP
Most razor burn clears up by itself. If the skin is still sore after several days, or you notice pus, swelling or redness that’s spreading, speak to a pharmacist or your GP.
