A thick cream like Vaseline (petroleum jelly) is highly recommended for a Kilimanjaro climb because the mountain’s environment—especially above ~4,000m—features extremely cold, dry, and windy conditions that rapidly dehydrate your skin.
Because the air becomes so thin and dry at such a high altitude, it is a good idea to pack Vaseline when climbing Kilimanjaro. Furthermore, it has the potential to turn quite chilly. As a result, your skin will get very dry very fast. Vaseline, a thick nourishing lotion, will keep your skin and lips moisturized. When your skin hurts from cleaning your runny nose, you may use it to soothe it in and around your nasal area.

Primary Reasons to Bring It
- Dry skin and face protection — Low humidity and high altitude suck moisture from your skin. Exposed areas (face, hands, lips) can become cracked, flaky, or painful. A thick barrier cream locks in moisture better than regular lotions.
- Chapped lips and windburn — Summit night involves hours of freezing winds and sub-zero temperatures. Lip balm alone may not suffice; Vaseline provides a durable protective layer that prevents cracking and soreness. Many packing lists specifically highlight it for the nighttime summit push.
- Chafing prevention — Long days of hiking with a pack, in layers, or with friction-prone areas (thighs, underarms, feet) can cause irritation. Apply it preventively to hotspots.
- Multi-purpose use — It can soothe minor cuts, help with dry nostrils (from breathing cold dry air), or even act as a barrier for blisters when combined with tape/socks.
The air thins and dries out significantly at altitude, amplifying these issues even in good weather.
Practical Tips
- Bring a small travel-size tube or jar (it’s lightweight and compact).
- Apply liberally at night and before summit day, especially on lips, face, and hands.
- Pair it with high-SPF sunscreen (UV is intense) and a buff/balaclava for extra protection.
- Alternatives like Aquaphor work similarly and are popular among climbers.
It’s a cheap, versatile item that many trekkers say they were glad to have—preventing discomfort that could distract from the experience. Most standard Kilimanjaro packing lists include Vaseline or heavy moisturizer for these exact reasons. Stay protected and enjoy the climb!
