If you live on Colorado’s Western Slope, you’ve probably noticed something curious. The sun feels warm and beautiful most of the year - but over time it can also be surprisingly harsh on the skin. People who move here often remark that their skin suddenly feels drier, more weathered, or harder to keep hydrated.
The reason isn’t just the dry air. It’s also the sun itself.
At higher elevations, sunlight behaves differently than it does at sea level. The same sunshine that makes Colorado’s landscapes so striking also carries stronger ultraviolet (UV) radiation, which can affect the skin in ways many people don’t expect.
Understanding why this happens can help you care for your skin more effectively in high-altitude environments.
The Science of High Altitude Sun
The higher you go above sea level, the thinner the atmosphere becomes. That thinner atmosphere filters less of the sun’s ultraviolet radiation before it reaches the ground.
Researchers estimate that UV exposure increases roughly 10–12% for every 1,000 meters (about 3,280 feet) of elevation.
Much of the Western Slope sits between 4,500 and 6,000 feet above sea level, with nearby mountain areas rising far higher. This means people living and working here often experience noticeably stronger UV exposure than those at lower elevations.
Colorado also receives an unusually large number of clear, sunny days each year, which increases overall sun exposure over time.
In short, the combination of altitude, dry air, and abundant sunshine means that skin in this region is regularly exposed to intense sunlight.
How Strong Sun Affects the Skin
Ultraviolet radiation interacts with skin in several ways. Over time, frequent exposure can contribute to:
• increased dryness
• reduced skin elasticity
• uneven tone
• fine lines or rough texture
Sun exposure can also encourage the formation of free radicals — unstable molecules that may contribute to visible signs of skin aging.
Because high-altitude environments often combine strong UV exposure with low humidity and wind, the skin barrier can become more vulnerable to moisture loss.
This is why many people living in dry mountain climates find that their usual skincare routines suddenly stop working as well.
Why Dry Air Makes Sun Damage Worse
Colorado’s climate is naturally arid. Humidity levels are often far lower than in coastal or eastern regions of the United States.
When humidity is low, the skin loses moisture more easily. Add strong sunlight and wind, and the skin barrier may struggle to maintain hydration.
This combination can lead to skin that feels:
• tight
• dry
• easily irritated
• more reactive to sun and weather
For this reason, skincare in high-altitude environments often focuses on protecting the skin barrier and reducing moisture loss.
Natural Ways to Support Skin in High Sun Environments
For generations, people living in sunny, dry climates have turned to botanical oils, plant extracts, and protective salves to help shield the skin from harsh environmental conditions.
Many of these traditional approaches are still valued today.
Antioxidant-Rich Botanicals
Plants produce antioxidants to protect themselves from environmental stress, including sunlight. When used in skincare preparations, antioxidant-rich botanicals can help support skin exposed to sun and weather.
Herbs and oils traditionally associated with antioxidant support include:
• Rosehip seed oil – rich in naturally occurring vitamins and fatty acids
• Chamomile – long used in calming herbal preparations
• Calendula – valued in traditional skin remedies
• Lavender – often included in botanical skincare blends
These ingredients are commonly found in herbal creams and oils designed for daily skin support.
Protective Plant Oils
Certain plant oils have been prized for centuries because they help slow moisture loss from the skin.
These oils create a light protective layer that helps the skin remain supple even in dry conditions.
Examples include:
• almond oil
• coconut oil
• castor oil
• raspberry seed oil
• rosehip seed oil
When blended into creams and balms, these oils can help support the skin’s natural barrier.
Rich Creams vs. Thin Lotions
In very dry climates, lightweight lotions often evaporate quickly because they contain a high percentage of water.
Thicker creams and botanical balms typically contain more oils and protective ingredients, which allows them to remain on the skin longer and help reduce moisture loss.
This is one reason traditional herbal skincare preparations often rely on richer formulas rather than thin lotions.
A Botanical Approach to Western Slope Skin
For people living in sunny, high-altitude environments like Colorado’s Western Slope, skincare often becomes less about quick moisture and more about supporting the skin’s natural defenses.
A thoughtful routine may include:
• gentle cleansing
• antioxidant-rich botanicals
• protective plant oils
• nourishing creams that help maintain hydration
Many modern herbal skincare preparations continue to follow the same principles used in traditional apothecaries — combining botanical oils, herbs, and natural ingredients designed to support the skin in challenging environments.
At Smittys Little Farm, our own formulations are inspired by these long traditions of botanical care. Preparations like Golden Emollient Cream rely on rich plant oils and herbal ingredients intended to support skin exposed to the dry air and bright sun common on Colorado’s Western Slope.
Living Well Under a Big Western Sky
The strong sunshine of the Rocky Mountain region is part of what makes life here so beautiful. From clear winter days to bright summer afternoons, the sun shapes everything from the landscape to the way we care for our gardens and our skin.
Understanding how altitude affects sunlight allows us to make simple, thoughtful choices that help keep skin healthy and resilient.
With the right combination of protective habits, botanical ingredients, and nourishing skincare, it’s entirely possible to enjoy the bright Western sky while keeping your skin comfortable and well cared for.
