Razor Burn versus Razor Bumps
Razor bumps are ingrown hairs that result from hair removal. Razor burn looks more like streaks or blotches across the skin. Both cause redness and irritation.
What causes redness after shaving?
When you shave, the razor can open small cracks in the top layer of the skin, triggering irritation and redness. Additional factors include: using a blunt razor, shaving against hair growth, shaving too fast, and having sensitive skin.
How to avoid redness after shaving: 6 steps
Step 1 — Prepare your skin
Cleanse with a gentle, hydrating cleanser. Our Red Algae Cleansing Soap Bar gently exfoliates, removes dead skin cells, and hydrates with coconut oil and shea butter to prevent cracking.
Step 2 — Use a sharp razor
Dull blades tug at hair follicles, causing irritation. Always use a sharp razor and replace blades regularly.
Step 3 — Apply soothing shaving cream
Use a shaving cream formulated for sensitive skin with anti-inflammatory ingredients like aloe vera and chamomile. Apply generously and let sit for 1–2 minutes before shaving.
Step 4 — Shave with the grain
Shave in the direction of hair growth using short, gentle strokes. This minimises friction and reduces the likelihood of razor burn.
Step 5 — Rinse with cold water
Cold water constricts blood vessels and closes pores, immediately reducing redness. Pat dry — never rub.
Step 6 — Apply a calming aftershave gel
The Recovery & Repair Gel is a natural Red Algae gel that tackles inflammation and sensitivity while moisturising the skin. Proven to reduce redness by 21% in just 28 days.
