Squalane is so similar to the lipids that our skin produces that it works perfectly to create a natural barrier on the skin. It does this without being too heavy or occlusive. The molecular structure of squalane allows it to deeply penetrate the skin and make your face feel smoother and better over time. 
Hydration and moisturization are two different things. Hyaluronic acid is a humectant that hydrates your skin. Squalane is an emollient that seals in moisture and hydration.
They are both equally great ingredients, but they are best if used together. Especially if you are using hyaluronic acid, you should add an emollient to add on top of it to prevent trans epidermal water loss. What’s the point of adding a humectant that will hold more water in your skin if you are just gonna let it all escape?
Squalane oil is effectively a moisturizer for your skin. The serum-like consistency absorbs well into the skin and prevents water loss.

Despite the conflict, we can safely say that squalane oil is probably the least likely of all skincare oils to cause trouble for oily or acne-prone skin.
