Thank you for your question. Sun bathing before breast augmentation surgery should be okay. Nothing should be done excessively, and I’m sure you do not plan to either. Put on your sun screen to prevent sun burns, especially in the areas of the breast. Moderate sun bathing should not interfere with the results of your breast augmentation surgery. All this being said, after your surgery, you should try to avoid sun exposure for at least 6-8 weeks, especially those tanning beds. Sun burns may negatively affect the wound healing process. For example, a sunburn can change the distribution and function of disease-fighting white blood cells for up to 24 hours post-sun exposure. If you do sun-bathing for a long-time before surgery, it may affect the healing of your breasts after augmentation. Two, they have a negative impact on the quality of your skin. Studies show that on a cellular level, increased UV exposure caused on swelling of endothelial cells (cells of blood vessels), and causes infiltration by white blood cells, and reduced the tensile strength of wounds. UV rays also speed up aging and sagging of the skin by destroying collagen resulting in premature wrinkling, brown ‘liver’ spots and loss of skin elasticity. Three, your breasts will be more sensitive to sunburns resulting in more pain during the recovery period. Five, the UV exposure can worsen the scarring (i.e., incision scars) and cause its hyperpigmentation and darkening. That being said, you are allowed to get sun exposure as it is important for vitamin D production, etc. However, it is important to always wear sun screen with both UVA and UVB protection with spf greater than 30. After your surgery, you should cover your scars during tanning as they can take up to one year to fully mature. Hope this helps.
