The emoji 🫪 ("melting face") and 🫩 ("biting lip") were both introduced in Unicode 14.0 (2021), but their adoption and support across platforms (like iOS, Android, Windows, etc.) can vary due to a few reasons:

1. Platform-Specific Design Choices

• Visual Complexity: The 🫪 emoji has a more abstract, surreal design (a face melting into a puddle), which might require more artistic interpretation. Some platforms may delay or simplify its rendering compared to 🫩, which is a more straightforward expression (a face biting its lip).
• Prioritization: Platforms like Apple, Google, or Microsoft may prioritize emojis based on perceived popularity, cultural relevance, or technical ease of implementation. 🫩 might have been seen as more universally useful or easier to design.

2. Unicode Consortium Guidelines

• While both emojis were added in the same Unicode version, the Unicode Consortium (which standardizes emojis) doesn’t enforce how quickly vendors must adopt them. Vendors decide when to include new emojis in their updates.
• Some platforms may roll out emojis in phases, especially if they require custom animations or complex graphics.

3. User Demand and Trends

• Emojis that gain early viral popularity (e.g., through memes or social media) often get prioritized by platforms. 🫩 might have been more widely used or requested by users, prompting faster adoption.
• 🫪, while popular in niche communities (e.g., for expressing anxiety, exhaustion, or humor), may not have had the same immediate demand.

4. Technical Limitations

• Older devices or operating systems may not support newer emojis until they receive updates. If a platform’s user base is slow to update, they might deprioritize less commonly used emojis like 🫪.
• Some platforms (e.g., Windows) have historically been slower to adopt new emojis compared to iOS or Android.

5. Design Consistency

• Platforms aim for visual consistency across their emoji sets. If 🫪 didn’t fit well with a platform’s existing emoji style, it might have been delayed or redesigned, causing uneven support.

Current Support (as of 2026)

• 🫩 (Biting Lip): Widely supported on most major platforms (iOS, Android, Windows, Twitter, etc.).
• 🫪 (Melting Face): Supported on most modern platforms, but may still appear as a black-and-white outline or missing on older systems.

How to Check Support

If you’re seeing 🫪 as a blank or monochrome emoji, it likely means your device or app hasn’t updated its emoji font. Try:

• Updating your OS or app.
• Using a platform that supports it (e.g., iOS 16+, Android 13+).

Fun fact: Both emojis were part of a wave of new expressive faces in Unicode 14.0, including 🫤 (saluting face) and 🫥 (dotted line face), which also saw varied adoption rates.
