Newbie w/ Self Tanners- HELP!

Just as the title says.. I am totally a newbie when it comes to self tanning products! I actually tan pretty well in the sun, however I have had 2 open heart surgeries in the last 3 years (most recently was only 4 months ago!!!!) … therefore, hospitalizations, health concerns, certain medications limiting sun exposure .. etc etc.. have made it so I’ve been quite pale these last few summers, and I am over it!! I am finally (pretty much) back to my old healthy self - feeling much better health AND confidence wise - but still gotta limit my sun time for the rest of the summer. I just ordered & received “Bondi Sands Everyday Gradual Tanning Milk” … any experience with this product? Any tips on application? Or even suggestions for other self tanners that y’all have had success with? ……Thanks all my Picky Peeps💖
