What Can Damage Your E-Liquid

• Avoid extreme heat. Heat can damage your e-liquid. Making the ingredients separate, the nicotine become weaker, and the e-liquid to darken in color. 
• Avoid very cold temperatures. If your e-liquid becomes cold it will thicken up, and not wick as well. 
• Keep your e-liquid out of direct sunlight. Sunlight can damage your e-liquid and cause it to darken, the ingredients to separate, weak the nicotine and make it taste bad. 
• Always recap the bottle after using it. Leaving the top off can lead to the e-liquid getting darker and the nicotine becoming weaker.
