Skin produces oil to maintain balance. Without oil the skin can become overly dry, leading to the formation of fine lines, wrinkles and breakouts. When the natural oils are stripped (this can occur from oil-reducing products or a strong foaming cleanser) the body then produces more oil to compensate and replenish the skin.
An oil will moisturise and replenish the skins barrier and can also help balance the skin's sebum production. They are also loaded with vitamins and minerals and contain antibacterial and anti-inflammatory properties.
Moisturisers are a combination of water and oil, and other active ingredients that help these two mix. They can contain up to 90% water and the key function of this product is to hydrate the skin.
Just as on any surface, moisture evaporates from the skin, that’s where oils come in! They rebalance the skin’s protective barrier which helps lock in that moisture.
Which is better? Well, each have different, but important roles to skin health, so we actually need both moisturiser and face oil!
