What is the structural difference between sensitive and sensitised skin?
Sensitive skin is a permanent genetic trait characterised by an inherently thin skin barrier and reactive nerve endings. Sensitised skin is a temporary condition triggered by external factors like over-using harsh retinoids, resulting in a damaged barrier that can affect any skin type.
What skincare ingredients should sensitive skin completely avoid?
Sensitive skin should bypass drying denatured alcohols. Avoid strong physical scrubs and aggressive chemical peeling agents, choosing low-dose, slow-release formulas instead.
How can I safely patch-test a new cosmetic product?
Apply a pea-sized amount of product to a hidden, thin area of skin like the inner forearm or behind the ear for 24–48 hours. Monitor the test spot for signs of swelling, immediate redness, tingling, or itching before applying it all over the face.
Why does my face sting even when using "gentle" moisturisers?
When the lipid barrier is severely compromised, raw nerve endings become exposed near the skin surface. Even benign ingredients can hit these nerves, triggering a stinging response until the skin's barrier lipids are restored.
Can I still use anti-ageing retinoids if my skin is sensitive?
Yes, but you must alter the technique. Choose encapsulated or low-percentage retinol, or retinal, and introduce them slowly, once or twice a week. Layering product over your moisturiser (the "sandwich method") also buffers direct exposure and reduces the risk of irritation.
