As the temperatures rise, off we head, swimsuit (and hopefully sunscreen) in hand, to the closest beach, pool or lake we can find. No harm in a quick dip right? Well, not exactly! The team from Dermalogica explain.
An Ocean Swim
Rich in trace elements and minerals, and with a composition not dissimilar to human blood plasma, seawater, arguably, has many unique healing properties for the skin. Many skin health benefits are specifically attributed to the Dead Sea, such as treatment for eczema, psoriasis and other extreme, dry skin conditions. Yet it is important to note that these benefits do not come from “salt” or sodium chloride, but from the high magnesium levels found in this body of water.
Nonetheless, it’s not all good news. Salts in high quantities can be the skin-drying scourge of the summer flesh baring masses. Diluted salt is almost impossible to remove from the skin with lye based soap or non-foaming wash, so even after showering, traces of salt deposits may remain on the skin, absorbing essential moisture. Couple this with excessive sun exposure and you have a dehydrated skin with an impaired barrier function – never a great combination!
A Day at the Pool
Chlorine is a toxic chemical; it has been used in water systems to combat disease for over 100 years. It is a necessary component of swimming pools and hot tubs, due to its disinfectant qualities. Chlorine’s harsh composition strips the skin of its natural lipids, therefore exacerbating moisture loss in the skin that leads to dehydration. Showering immediately after exposure can help to reduce the moisture loss by ensuring the skin does not suffer prolonged contact.
Another potential risk of chlorine exposure is skin irritation. While technically water proof, our skin has the capacity to
absorb chemicals from water sources. This means that low level exposure to chlorine, as found in swimming pools, can cause skin irritation in the form of contact dermatitis. Wetting the skin with non-chlorinated water prior to exposure can lessen the amount that can be absorbed and lower the risk of irritation.
And on that note, chlorine & salt deposits are not the only culprits of swimming related dehydration. Water itself (ironically) removes moisture from the skin, and need we talk ocean pollution?
Summer swim trips can still be fun; just follow these post-dip skin steps to maintain a healthy, hydrated summer skin:
• Shower as soon as possible after swimming – and don’t forget to reapply that sunscreen if staying outdoors.
• Cleanse the skin with Dermalogica Conditioning Body Wash.
• Exfoliate with products such as the Dermalogica Daily Microfoliant or Dermalogica Exfoliating Body Scrub.
• Moisturise, moisturise, moisturise! Lock in hydration; repair the barrier function and calm irritation with Dermalogica Barrier Repair or your prescribed moisturiser.
