To be honest, Slimthicccsenpai did reveal her face, yet not to the extent anyone could recognize her.
She disclosed some pictures where she can be seen without wearing the mask.
Slimthicccsenpai either shares a picture of the upper half of her face or the lower half of her face.
However, she hasn’t fully shared a picture of her face as a whole until this day.
For instance, in the above picture, she has only shown the upper half of her face.
Slimthicccsenpai’s age seems to be around 20-25 years old based on her appearance.
That being said, the TikTok star neither any trusted sources have substantiated the number.
In addition, insights relating to her introduction to the world remain obscure.
