Let me start by saying, this little 1 fl oz bottle packs a serious punch! I've been using the SunFX Sunless Tanning Additive for a few weeks now, and it's become my secret weapon for achieving that perfect sun-kissed glow while fighting off fine lines.

The first thing I noticed was how seamlessly it blends with my regular tanning solution. No weird separation or texture changes - just smooth, easy application. The fact that it's vegan and cruelty-free is a huge plus for me personally.

Where this product really shines (pun intended) is in its dual action. While developing my tan, I could actually feel my skin getting more hydrated thanks to the hyaluronic acid. After about three uses, I noticed my skin looked plumper and those pesky forehead lines seemed less noticeable.

One of my favorite ways to use it is mixing a few drops with my post-tan moisturizer. It gives this incredible radiant finish that makes the tan look even more natural while continuing to deliver those anti-aging benefits.

Now for the reality check - you do go through this bottle pretty quickly if you're using it regularly like I am. At about 5-6 drops per application, I find myself reordering more often than I'd like. But considering the results, it's worth the investment.

The lack of fragrance might disappoint some, but I actually appreciate it - no competing scents with my other products. My husband even stole some for his routine and now swears by how it improves his skin texture without any greasy residue.

Bottom line? If you want more than just color from your sunless tanning routine - if you want actual skincare benefits - this additive delivers. It's like getting a facial treatment while you tan. Just be prepared to budget for regular repurchases!
