**Denver's Altitude: Is Air Conditioning Dehydrating Lasers?**

By Franklin Everett Shaw

The mirror reflects more than just your image in Denver. It reflects the harsh reality of the city’s high-altitude climate, especially when considering cosmetic procedures like laser treatments. Many chase the promise of rejuvenated skin or permanent hair removal, but few fully grasp the amplified dehydration risk lurking beneath the surface. It’s a double whammy: the already arid air of Denver combined with the artificial dryness of air conditioning, all conspiring to sabotage your skin’s healing process.

Denver’s altitude, sitting a mile above sea level, presents a unique challenge. The air is thinner, meaning less oxygen and lower humidity. This leads to increased transepidermal water loss (TEWL), where your skin loses moisture at a faster rate than at lower altitudes. Think of it like leaving a glass of water out in the sun; it evaporates quicker. Your skin is that glass of water.

Air conditioning, a near-constant companion during Denver’s summer months, further exacerbates this dehydration. Air conditioners work by removing moisture from the air, creating an artificially dry environment indoors. This pulls even more moisture from your skin, compounding the effects of the altitude.

Laser treatments, while effective, intentionally cause controlled damage to the skin. This damage triggers the body’s natural healing response, which requires ample hydration. Dehydrated skin struggles to heal efficiently, leading to:

• Prolonged redness and inflammation.
• Increased risk of scarring.
• Suboptimal results from the laser treatment.
• Increased discomfort and itching.

So, what can a Denver resident do to combat this compounded dehydration risk and ensure optimal results from laser treatments? It starts with a proactive hydration strategy, both internally and externally.

Pre-Laser Hydration Protocol:

1. Hydrate from Within: Begin increasing your water intake at least one week before your scheduled laser treatment. Aim for at least half your body weight in ounces of water per day. For example, if you weigh 150 pounds, drink at least 75 ounces of water daily. Add electrolytes to your water to improve absorption. Consider using electrolyte tablets or powders readily available at sporting goods stores like those near Sports Authority Field at Mile High.

2. Humidify Your Environment: Invest in a humidifier, especially for your bedroom. This will help combat the drying effects of air conditioning while you sleep. Aim for a humidity level between 40-60%. You can find affordable humidifiers at stores like Target in Stapleton.

3. Avoid Diuretics: Limit your consumption of caffeine and alcohol in the days leading up to your treatment. These substances can dehydrate you further. Opt for herbal teas or water infused with fruits like cucumber and lemon.

4. Moisturize Diligently: Apply a rich, hydrating moisturizer to your skin twice daily, focusing on the area to be treated. Look for ingredients like hyaluronic acid, ceramides, and glycerin, which help attract and retain moisture. CeraVe Moisturizing Cream is a readily available and effective option.

Post-Laser Hydration Protocol:

1. Continue Increased Water Intake: Maintain your increased water intake for at least two weeks after your laser treatment. Your body needs ample fluids to repair and regenerate skin cells.

2. Gentle Cleansing: Use a gentle, fragrance-free cleanser to wash the treated area. Avoid harsh soaps or scrubs that can further irritate the skin. Cetaphil Gentle Skin Cleanser is a dermatologist-recommended choice.

3. Apply a Healing Ointment: Apply a thick layer of a healing ointment like Aquaphor or Vaseline to the treated area. This will create a protective barrier and help lock in moisture. Reapply frequently throughout the day, especially after cleansing.

4. Avoid Sun Exposure: Sun exposure can significantly hinder the healing process and increase the risk of hyperpigmentation (darkening of the skin). Wear protective clothing and a broad-spectrum sunscreen with an SPF of 30 or higher whenever you are outdoors. Even on cloudy days, UV rays can penetrate and damage your skin.

5. Cool Compresses: Apply cool compresses to the treated area to reduce inflammation and discomfort. You can use a clean cloth soaked in cool water or a gel pack wrapped in a towel.

Dermatologist-Recommended Skincare Routine for Denver’s Dry Climate:

Beyond the pre- and post-laser protocols, Denver residents should adopt a year-round skincare routine that prioritizes hydration.

• Morning:
  • Gentle cleanser.
  • Hyaluronic acid serum.
  • Moisturizer with SPF 30 or higher.
• Evening:
  • Gentle cleanser.
  • Hydrating serum (e.g., niacinamide or vitamin C).
  • Rich moisturizer.
  • Consider adding a facial oil for extra hydration, especially during the winter months.

Common Mistakes and Pitfalls:

• Not drinking enough water: Many people underestimate their daily water needs, especially in Denver. Track your water intake to ensure you are meeting your hydration goals.
• Using harsh skincare products: Avoid products containing alcohol, fragrances, or harsh exfoliants, as these can further dry out your skin.
• Skipping sunscreen: Sunscreen is essential year-round in Denver, even on cloudy days.
• Ignoring signs of dehydration: Pay attention to your body’s signals, such as dry mouth, headache, and fatigue. These are signs that you need to drink more water.
• Assuming all moisturizers are created equal: Look for moisturizers with humectants (like hyaluronic acid), emollients (like shea butter), and occlusives (like petrolatum) to provide comprehensive hydration.

Real-World Scenario:

Consider a Denver resident, Sarah, who undergoes laser hair removal on her legs. She lives in a condo downtown and works in an office building, both heavily air-conditioned. Without proper hydration, her skin becomes excessively dry and irritated after the treatment. She experiences prolonged redness, itching, and even some minor blistering. By following the pre- and post-laser hydration protocols outlined above, Sarah can significantly improve her healing process and achieve better results. She can also consult with a local Denver dermatologist, perhaps at the University of Colorado Hospital, for personalized skincare recommendations.

Laser treatments in Denver can be incredibly effective, but they require a proactive approach to hydration. By understanding the compounded dehydration risks posed by the altitude and air conditioning, and by implementing the strategies outlined above, Denver residents can ensure optimal healing, minimize complications, and achieve the beautiful results they desire. Don’t let the dry air steal your glow; hydrate your way to radiant skin.
