I’m happy with the ease of use and results I got using the Charlotte Tilbury light/medium tanning drops on my legs and arms just a couple evenings in a row (develops overnight). My skin is super pale, and the drops resulted in enough color so my skin had a lovely golden tone and didn’t stand out as being my normal stark white shade. I wouldn’t say my skin looked tan or turned a deep bronze shade (even when later using more drops), but my skin got enough color so it had more of a healthy look rather than being so pasty white.I find the drops easy to use and forgiving in that I simply used my hands (washed right after) and didn’t get streaks or dark areas where color grabbed too much. I did continue to use the drops a few more times during the week leading up to an outdoor event where I wanted to have a little color, though I didn’t perceive my skin as getting noticeably darker with continued use. That may be due to shaving a couple times and how I reapplied drops.My skin still had color for the event, but I feel the color looked best after the first two applications. Now that I know how the color develops and that it doesn’t get streaky on me, I’ll just wait until a couple days before I want some color to use the drops as I didn’t really notice further darkening with continued use. The shade actually looked good after just one night but a second application let me even out the color as I had concentrated a little less on the back of my legs.I feel continued use was more about maintaining color. It may be Fromm choosing the lighter shade, or because I shaved a couple times or even because I used different techniques applying the drops and was imprecise as to amount used. Directions say the drops can be applied directly to the skin or added to moisturizer. The drops are alcohol based and my skin gets very dry, and my best results occurred applying the drops at night (showered in the a.m.) after applying a small amount of body cream first and smoothing a little more cream over the same areas after (slightly different than the directions).I also tested how it worked simply adding drops to my cream and I did get color, but I feel I got more color putting the drops directly on my lightly moisturized skin. When mixing the drops, I may have used too much cream given my dry skin and that likely diluted the drops or may have made my skin less prone to absorb as much of the drops. I can’t say this is the product I’d use (though maybe in the darker shade) if I wanted to get dark enough to look tan, but these drops did give my skin the level of color I anticipated and wanted.My sensitive, dry skin has had no negative reaction. However, I can’t say if it might irritate the more sensitive skin on my face as I haven’t used the drops on my face as my skin tone looks more even when pale, plus I avoid products with drying alcohol on my face. I do notice a faint, slightly unpleasant, odor on my legs while the tanner develops. I do believe that’s common from the interaction of DHA with amino acids on the skin surface, but not everyone gets it and there are ways to minimize it. Overall, like it a lot. 4.5 stars.
