What is the difference between dry and dehydrated skin?
People assume that the terms dry and dehydrated are interchangeable when referring to skin but little do they know there is a chasm between the two terms.
Dry skin or alipidic (if you are into impressing others -which means without lipids) does not produce oil. Skin follicles are very small and the sebum production is minimal. Smaller follicles indicate dry skin. The purpose of the natural oil that our skin produces is to hold onto moisture. If skin has no ability to produce natural oil moisture evaporates and problems arise making skin rough, taut and flaky.
Dry skin lacks oil.
Dehydrated skin is not a skin type but a skin condition and it does not discriminate. You can have oily, dry, combination or acne prone skin and still have dehydrated skin. Dehydrated skin is caused by topical skin care and external aggressors like pollution, weather, smoking, artificial environment, harsh ingredients and products, medication, not drinking enough water, long hot baths and showers, over cleansing, chlorine and alcohol.
Dehydrated skin lacks water.
Dry skin – a skin type
Very sensitive to touch
Slight tingling or smarting after cleansing
Make up stays longer
General discomfort when applying make up or skin care
Dehydrated skin – a skin condition
Feels oily and dry at the same time
Skin taut after cleansing
Pores are enlarged
Black heads appear more readily
Skin care products are absorbed too readily – it is never enough
Make up goes on patchy and stays patchy and oily
How to treat dehydrated skin
Seek professional analysis
Use a mild cleanser that does not strip skin
Use non-alcoholic toner
Avoid scrubbing brushes and harsh exfoliants
Water-in-oil moisturiser is a must
Avoid acids like AHA, BHA, Salicylic, Benzoyl peroxide, Sulphur topicals and acne treatment creams and retinol

A study published in the Journal of Applied Physiology in 2008 found that dehydration by -2.5% and -5.0% of body mass “…strongly increased cortisol, epinephrine, and norepinephrine, the primary stress hormones.” Judelson AD. et al. “Effect of hydration state on resistance exercise-induced endocrine markers of anabolism, catabolism, and metabolism.” Journal of Applied Physiology September 2008 vol. 105 no. 3 816-824
The Pinch-Pout face test
Dehydration often reduces skin elasticity, so take this test to find out if you are dehydrated. After washing and drying your face pinch the skin on the bridge of your nose for a few seconds and release – the skin should snap back immediately if it maintains it for a few seconds – you are dehydrated.
You can try this also by puckering your lips and when you relax if the skin around your mouth does not snap back rapidly and the creases hold for a few seconds – you are dehydrated
