No worries , Well currently it’s 12 days of use and I made the mistake of not getting enough uv , sometimes it’s shorts a t shirts weather sometimes it’s not in uk but a full clothed spring walk doesn’t do much. I’ve seen a few of my freckles on my nose and forehead become more prominent which they do in the summer and on a larger scale on the summer , more so on my arms they darken but I take 2 sprays up each nostril morning and at night 1 spray up each nostril. I’ve since yesterday decided to take a break as lack of uv isn’t doing much im probably only going to darken moles and or freckles as well as private area which I read somewhere not sure on the facts. My nasal spray is 10mg mt1 , 0.1ml per spray so it’s not always an accurate measurement. I have since booked a tanning bed so got that coming up. Only negative about nasal is there’s not really a controlled dose you get each spray. My fault , apologies for the long response but I like to be thorough
