Glow up!
Color: #2 ROSE, Color: #2 ROSE
I bought this for a cruise to the Caribbean and it was perfect! I applied it before heading to the beach. Then reapplied once I got to the beach. The oil is light and doesn’t feel oily at all. It leaves your skin with a very natural glow and softens your tan. The scent is light but elegant, not over powering. I love it!

Love this oil!
Color: #2 ROSE
Great oil. I have problems with dry skin and this oil adds moisture and a little glow to complement the perfect outfit. It looks just as good on my tan skin as it does on my off-season, lighter skin tone. Great price point too!
