The yellow one is more famous, and I was torn between the two, but I wanted firmness, so I went for the pink one. It has a sticky texture, and it feels strangely like a film is covering your lips, but it's not sticky or bothersome. Just be careful not to use too much! I usually use it before bed, and the next morning, my lips are surprisingly not dry, and there's no irritation at all! I regret not having started using it sooner (;_;)
