But some of her followers weren't so happy about her transformation and urged her to be more natural.

In the photos and videos, Olivia wore her long hair wavy and a fresh face of makeup.
She captioned the post: Makeup by @novakaplan Hair @bykileyfitz (getting your DMs and 1. Yes it’s all my own hair. And 2. Kiley used a flat iron to put these waves in)”.
The compliments poured in calling her "beautiful," and "gorgeous," but some thought she'd covered up one of her biggest assets - her freckles!
Olivia looked flawless in her selfie but fans noticed her freckles were missing
"Don't hide your freckles," wrote one, while another said: "Be natural. You don’t even need makeup Olivia, natural beauty girl."
Olivia faded her famous freckles several years ago when she switched up her skincare routine.
At the time she said: "Got rid of sunspots. I love my freckles. But over the past couple of years I’ve seen more come up and merge with other freckles to make large dark spots."

She added: "Dark spots prevent your skin from reflecting light and gives you a dull complexion. So for the past year, I’ve been diligently using @Proactiv Mark Fading Pads. I wipe my face with one every night and now my face has a more even tone and the large spots aren’t as noticeable."
Olivia also credits exercise for keeping her complexion glowing and says she stays age-defying with a consistent wellness regime.
