How long after breast augmentation can you go tanning?

Yes, you can tan, but make sure that any scars are covered and that you wear plenty of sunscreen. My best,

Keep the sun away from scars is your best bet. Scars behave differently in different people and can become too dark permanently (hyperpigmentation or dyschromia) if exposed to the sun. Or as you mentioned it may stay white while your skin tans around it. Better to spray tan if you want to hide it. Definitely use a strong SPF (>30) sunscreen on it even though it is hidden by your bathing suit as some sun goes through the fabric.

Follow the advice of your surgeon, but I advise my patients that they can go tanning as early as three weeks after surgery. I tell them to be sure to protect their incisions with sunscreen that has a sun protection factor (SPF) of 15 or higher. Ultraviolet light, whether from the tanning bed or the sun at the beach, can make a scar redder for a longer period of time. For more information on this and similar topics, I
recommend a plastic surgery Q&A book like "The Scoop On Breasts: A
