Denver Skin: Altitude Lies About Summer Vaseline?

By Franklin Everett Shaw

December 26, 2025

The Denver sun is no joke. It’s intense, relentless, and amplified by the altitude. Many Denver residents find their skin drier than the Sahara, especially during the summer months. So, can Vaseline, that ubiquitous petroleum jelly, be your skin’s savior in the Mile High City? The answer is nuanced, and it’s time to cut through the myths and get to the truth.

Vaseline, or petroleum jelly, is an occlusive moisturizer. This means it creates a physical barrier on the skin, preventing water loss. It doesn’t add moisture; it traps what’s already there.

Now, let’s address the elephant in the room: the altitude. Denver’s high altitude (5,280 feet above sea level) contributes to lower humidity. This means the air is drier, pulling moisture from your skin at a faster rate.

The concern is that Vaseline, being occlusive, might trap existing dryness, potentially exacerbating the problem. Some also worry about it clogging pores, especially in the summer heat.

Let’s debunk some myths and establish best practices for Denverites.

Myth 1: Vaseline clogs pores.

While Vaseline can trap debris on the skin, it’s not inherently comedogenic (pore-clogging). The key is application.

• Proper Application: Never apply Vaseline to dirty skin. Always cleanse your face thoroughly before applying a thin layer. Think of it as sealing in hydration, not dirt.
• Strategic Use: Consider using Vaseline as part of a “slugging” routine at night. This involves applying a thin layer over your regular moisturizer to lock in hydration while you sleep.
• Avoid Heavy Application: In the summer, especially during the day, avoid applying a thick layer of Vaseline, particularly if you’re prone to sweating. This can create a breeding ground for bacteria.

Myth 2: Vaseline makes you more sun-sensitive.

There’s no scientific evidence to suggest Vaseline increases sun sensitivity. However, it offers no sun protection.

• SPF is Non-Negotiable: In Denver, sunscreen is your best friend, year-round. Apply a broad-spectrum SPF 30 or higher every morning, regardless of the weather.
• Vaseline and Sunscreen: If you choose to use Vaseline during the day, apply it after your sunscreen has fully absorbed. Vaseline should be the last step in your skincare routine.
• Consider Tinted Sunscreens: For a bit of coverage and sun protection, explore tinted sunscreens. Many brands offer formulations that blend seamlessly into the skin.

Myth 3: Vaseline is the only moisturizer you need.

While Vaseline is excellent at preventing water loss, it doesn’t contain hydrating ingredients like hyaluronic acid or glycerin.

• Layering is Key: In Denver’s dry climate, layering your skincare is crucial. Start with a hydrating serum, followed by a moisturizer, and then, if needed, a thin layer of Vaseline.
• Humectants First: Look for moisturizers containing humectants like hyaluronic acid, glycerin, or aloe vera. These ingredients draw moisture from the air into your skin.
• Emollients Second: Follow with an emollient moisturizer containing ingredients like shea butter, ceramides, or squalane. These help to soften and smooth the skin.

Alternative Moisturizers with SPF for Denver Summers:

Vaseline alone isn’t enough, especially during the day. Here are some excellent alternatives that combine hydration and sun protection:

• EltaMD UV Clear Broad-Spectrum SPF 46: This is a cult favorite for a reason. It’s lightweight, oil-free, and contains niacinamide to help calm redness and inflammation. It’s a great option for acne-prone skin.
• La Roche-Posay Anthelios Melt-In Sunscreen Milk SPF 60: This sunscreen is incredibly hydrating and absorbs quickly. It’s a good choice for dry or sensitive skin.
• CeraVe AM Facial Moisturizing Lotion SPF 30: This affordable option contains ceramides, niacinamide, and hyaluronic acid to hydrate and protect the skin. It’s a great everyday moisturizer with SPF.
• Supergoop! Unseen Sunscreen SPF 40: This sunscreen has a unique, velvety texture that feels like a primer. It’s oil-free and works well under makeup.

Specific Challenges in Denver and How to Overcome Them:

• Increased UV Exposure: Denver’s altitude means you’re closer to the sun, resulting in higher UV exposure. This increases your risk of sunburn and skin damage. Solution: Wear sunscreen daily, even on cloudy days. Reapply every two hours, especially if you’re outdoors.
• Dry Air: The low humidity in Denver can lead to dry, itchy skin. Solution: Use a humidifier in your home, especially at night. Drink plenty of water to stay hydrated from the inside out.
• Windburn: Denver’s windy conditions can strip the skin of its natural oils, leading to windburn. Solution: Protect your skin with a scarf or balaclava when spending time outdoors in windy conditions. Apply a thicker moisturizer to create a barrier against the wind.
• Chapped Lips: Dry air and wind can quickly lead to chapped lips. Solution: Use a lip balm with SPF throughout the day. Avoid licking your lips, as this can worsen dryness.

A Denver-Specific Vaseline Routine (Summer Edition):

Here’s a sample routine for Denver residents who want to incorporate Vaseline into their summer skincare:

• Morning:
  • Cleanse your face with a gentle cleanser.
  • Apply a hydrating serum (e.g., hyaluronic acid).
  • Apply a lightweight moisturizer.
  • Apply a broad-spectrum SPF 30 or higher sunscreen.
  • Optional: A very thin layer of Vaseline on extremely dry areas (e.g., around the eyes) after sunscreen absorption.
• Evening:
  • Double cleanse your face to remove makeup and sunscreen.
  • Apply a hydrating serum.
  • Apply a richer moisturizer.
  • Optional: “Slugging” with a thin layer of Vaseline over your moisturizer.

Common Mistakes and How to Avoid Them:

• Applying Vaseline to dirty skin: Always cleanse your skin before applying Vaseline.
• Using too much Vaseline: A thin layer is all you need.
• Forgetting sunscreen: Vaseline does not protect you from the sun.
• Not hydrating from the inside out: Drink plenty of water.
• Ignoring other skincare needs: Vaseline is not a substitute for a well-rounded skincare routine.

Vaseline can be a useful tool in your Denver skincare arsenal, especially during the dry summer months. However, it’s crucial to use it correctly and in conjunction with other hydrating and protective products. Remember, sunscreen is non-negotiable, and layering your skincare is key to combating the effects of altitude and dry air. By following these tips, you can keep your skin healthy and hydrated, even in the challenging climate of the Mile High City.
