Glowy skin hydration
Size: 6.8 Fl Oz (Pack of 1)
Golden goddess results unlocked !!!! If you’re not tan it adds a nice glow. But if you’re tan ( fake or not) this product will make your skin look hydrated, glowy, bronzed and highlighted. I’m on the older side so I have some crepey skin on my inner arms, this makes it look 100 times better. I also only self tan, I find this helps my “tan” last longer. Has a nice tropical scent that gradually fades.

Soft Bronzy Glow
Size: 6.8 Fl Oz (Pack of 1)
I received a stinky oil in a subscription box, I love how soft it makes my dry diabetic skin feel. Oil leaves skin much softer than a moisturizer does, however, I was put off by the strong magnesium smell. I found this Vaseline Oil online and decided to try it instead. Firstly, the smell is so much more enjoyable and the shine it left behind is unmatched. I used it directly after a shower, applying it to my skin while I was still partially wet. Doing this, traps moisturize in the skin and leaves behind a beautiful bronzy glow. Unlike my moisturizer, I find I do not need to reapply daily, instead I only use every 2 to 3 days because it keepsy skin so very soft. I would recommend this to any diabetic with dry skin.

Gorgeous Glow

This products leave the best subtle glow! The shimmer last very long and it isn’t greasy. I apply with a body brush or my hands and it spreads pretty evenly.

Works great, a tad "tacky" in feeling!
Size: 6.8 Fl Oz (Pack of 1)
Mixed review. The product smells great, provides good moisturizing effects and glistens on the skin. Drawback, it remains sticky on the skin. It is an oil so some oily feeling is to be expected, but the tackyness is what I dislike. Especially when doing outdoor activities where everything that drifts in the wind will stick to your skin due to the oil. If you do not mind that feeling, you will love the product and the results.
