What Can Damage the Skin Barrier and Make Skin Feel Sensitive?

Cleansing & washing

• Harsh or high-pH cleansers
• Soap used repeatedly on the face
• Washing the face too frequently
• Very hot water
• Long hot showers
• Excessive cleansing or double-cleansing when it isn't needed

Exfoliation & skincare actives

• Over-exfoliating
• Frequent facial scrubs
• Using exfoliating brushes or cleansing devices aggressively
• Too many acids
• Strong AHA/BHA/peels used too frequently
• Retinoids introduced too aggressively
• Combining multiple strong actives
• Using high-strength products without allowing the skin to adapt
• Applying actives on an already damaged barrier

Shaving — especially important for men

• Shaving physically removes part of the superficial protective layer along with hair
• Repeated razor passes over the same area
• Shaving too closely
• Shaving with a blunt razor
• Shaving without adequate lubrication
• Shaving against the direction of hair growth
• Alcohol-heavy or irritating aftershaves immediately after shaving

For a period after shaving, the barrier is more vulnerable — which is why what a man puts on his skin immediately afterwards matters.

Physical damage

• Scrubbing the face with towels
• Rubbing or wiping the skin repeatedly
• Picking acne
• Scratching
• Friction from masks, helmets, chin straps or clothing
• Frequent waxing, threading or facial hair removal
• Dermaplaning
• Improper use of facial tools

Professional procedures

• Chemical peels
• Microneedling
• Lasers
• Microdermabrasion
• Dermabrasion
• Certain facials
• Waxing
• Any procedure that deliberately disrupts the stratum corneum while the skin heals

Environment

• Excessive sun/UV exposure
• Heat
• Cold weather
• Dry weather
• Low humidity
• Strong wind
• Air-conditioning
• Indoor heating
• Pollution
• Sudden climatic changes

Products & ingredients

• Fragrance
• Essential oils in susceptible skin
• High concentrations of alcohol
• Harsh surfactants
• Irritating preservatives or ingredients in susceptible individuals
• Products with unsuitable pH
• Using too many products at once
• Frequently changing skincare products

Lack of barrier support

• Not moisturising adequately
• Insufficient skin lipids
• Loss of ceramides, cholesterol and fatty acids
• Excessive removal of natural skin oils
• Dehydration of the stratum corneum

Lifestyle factors that can worsen sensitivity

• Stress
• Poor sleep
• Frequent swimming/chlorinated water
• Repeated sweating followed by harsh cleansing
• Excessive heat exposure

And importantly…

Not every case of sensitive skin comes only from barrier damage.

Conditions such as eczema, rosacea, contact dermatitis, allergies and certain inflammatory skin disorders can also cause sensitivity — although barrier dysfunction often accompanies many of them.

The key message for the reel

Your skin may not suddenly have "become sensitive."
Its protective barrier may simply be asking for help.

And for men:

Every shave temporarily challenges the skin barrier.
What you do to your skin immediately afterwards matters.
