Moisturizing Ingredients for Low Humidity Environments

Working in a low humidity environment like an airplane can make skin feel very dry. It's understandable that you're looking for moisturizers that won't exacerbate this issue by drawing moisture out of your skin.

Based on your experience and the information available, here are some insights and recommendations for ingredients that can help keep your skin hydrated in dry conditions:

• Hyaluronic Acid: You mentioned experiencing dryness with Hyaluronic Acid on the plane. This can happen with humectants in very low humidity if they don't have enough moisture to pull from the air, potentially drawing it from deeper skin layers instead. As the staff mentioned, using Hyaluronic Acid at a low concentration (e.g., not exceeding 0.1%) might help prevent this. Combining different molecular weights (like small and large) can also provide hydration at different skin levels. However, if you've had a negative experience, other options might be more suitable.

• Panthenol (Vitamin B5): The staff correctly pointed out that Panthenol is more than just a simple humectant; it's a moisturizing active that helps improve the skin barrier and reduce moisture loss. It's a good choice for dry conditions and is less likely to cause the issue you experienced with Hyaluronic Acid. You can use it at concentrations of 1-3%, and up to 5% for very dry skin. Options available include Panthenol (Vitamin B5, DL-Panthenol, Powder) and D-Panthenol Care (Pro-Vitamin B5, 100% Liquid).

• Natto Gum: You were right to question if Natto Gum would behave like Hyaluronic Acid in dry air. However, according to the staff and product information, Natto Gum (Nutto Gum) does not have the effect of drawing water from the skin in low humidity. It contains Polyglutamic Acid, which provides comprehensive moisture. It can be a good alternative or addition to your routine.

• MOIST72™: This ingredient is specifically designed for dry skin and provides continuous, long-lasting hydration (up to 72 hours). It does not draw water from the skin in dry conditions and is highly suitable for your situation.

• Ceramide: Ceramides are essential components of the skin barrier. Using Ceramides helps restore and strengthen this barrier, which is crucial for preventing moisture loss, especially in dry environments. They do not draw water from the skin. Ceramides are excellent for dry, sensitive, or compromised skin, as the staff noted. There are various types available, such as Cerasoft™ (Synthetic Ceramide), Skin-Barrier™ (Skin Barrier Restoration, Skin Mimic Ceramides Liposome), Ceramide Complex (Water/Oil Dispersible Powder), Ceramide 3 (Ceramide NP), Pseudoceramide (Cetylhydroxyproline Palmitamide), Cera-Flux V (Water Dispersible Ceramide Complex, 3 Types), Ceramide 6-II (Ceramide AP), Pseudo-Ceramide 104 (Hydroxypropyl Bispalmitamide MEA), Cera-Flux VX (Water Dispersible Ceramide Complex, 5 Types), Ceracare™ Liposome-3 (Liposome Ceramide Complex, 3 Types), Ceracare™ NP50 (Water/Oil Dispersible Ceramide NP), Ceracare™ Oil (Clear Oil Ceramide, 2% Minimum Ceramide), and Ceracare™ Wash-5 (Ceramide Depositing Lipid Particle).

Recommendation:

As the staff suggested, using a combination of moisturizers is often most effective for very dry conditions. Consider building a routine that includes:

1. Ceramides: To strengthen the skin barrier and prevent moisture loss.
2. Panthenol: To provide moisture, soothe, and support skin healing.
3. MOIST72™: For long-lasting hydration independent of air humidity.
4. Natto Gum: As an additional comprehensive moisturizer that doesn't pull water from the skin.

By combining ingredients that work in different ways – reinforcing the barrier and providing hydration through different mechanisms – you can create a more robust defense against the extremely dry air on the airplane and keep your skin comfortable both in the air and on the ground.
