24 to 48 hours after getting lip fillers, the use of a straw should be avoided as this can cause movement and pressure on that part. Straws could potentially cause larger suction than required, which might result in irritation or relocation of the filler. Focus on gentle care, including avoiding vigorous lip movements during the first recovery period. After the initial road to recovery, you can reintroduce using a straw gradually but it is always suggested that when taking up your treatment injection into account and consider how far through its healing process. Adhere to all post-treatment guidelines given by your health care specialist in order to achieve the best results and safety.
