Here are some Biological & Lifestyle Triggers that can make skin hypersensitive:

Genetics – If sensitive skin runs in your family, you may be more prone to it.
Hormonal fluctuations – During menstruation, pregnancy, or menopause, your skin may become more reactive.
Underlying skin conditions – Such as rosacea, eczema, or psoriasis increase skin sensitivity.
Aging – Thinner, more delicate skin becomes more reactive over time.
Allergies – Both food and environmental allergies can show up as skin irritation.

Stress – Increases cortisol levels, which can weaken your skin’s barrier and trigger inflammation.
Lack of sleep – Reduces skin regeneration, making it more prone to sensitivity.
Poor diet – Deficiencies in essential fatty acids, vitamins, or antioxidants can compromise skin health.
Smoking – Diminishes blood flow to the skin and increases oxidative stress.
Alcohol – Can dehydrate the body and increase skin flushing.
Caffeine – May cause redness or dehydration in sensitive individuals.
Overexertion (excessive workouts) – Sweat buildup and heat can irritate skin.
Inconsistent skincare routine – Switching products too often or overusing actives can disrupt your skin barrier.
