The efficacy and function of rosehip oil. I heard that this oil is also very friendly to oily acne skin.

Compared with traditional creams, lotions and essences, skin care oils are 100% oil, so they are more moisturizing and more suitable for "adding fuel" when you need it. Let’s take a look at the benefits and functions of rosehip oil.

The efficacy and function of rosehip oil

High content of unsaturated fatty acids with repairing and antioxidant functions. The biggest feature that distinguishes rosehip oil from other natural oils is that the content of unsaturated fatty acids is very high, basically reaching about 70-80%. In nature, perhaps only argan oil, known as "liquid gold", can be comparable to it.

Causes of acne

In fact, acne is not only caused by excessive oil secretion. Some studies in recent years have found that low linoleic acid content or high oleic acid content in the oil secreted by the skin can also cause acne. This is why some people with oily skin are less prone to acne, because linoleic acid can promote the formation of the skin barrier and also has a certain interference effect on Propionibacterium acnes. In a clinical study, adding 2.5% linoleic acid can significantly solve the problem of closed comedones. Compared with traditional bactericidal and anti-inflammatory ingredients, linoleic acid therapy is safer and gentler.

When should rosehip oil be used?

Characteristics of rosehip oil: high content of unsaturated fatty acids and retinoic acid, which can easily replenish lipids in damaged skin, effectively resist free radicals, and accelerate skin cell metabolism. Therefore, it is very suitable for repairing damaged skin barrier and improving dull skin condition after staying up late, and plays a role in brightening skin tone. As for the usage of this type of natural oil, it depends on the skin characteristics of different people. It can be added to facial cream for use, or used instead of essence. Generally 2 to 3 drops are enough. Don't be greedy. If you use too much, your face will easily become oily.

If you want to improve acne marks or new scars (it is ineffective on old scars), just apply a small amount directly to the area. There is also a water-oil-water method circulating on the Internet (from my favorite science blogger: The Beauty King and the Chemist): that is, use toner as a base first, then use rosehip oil for massage, and then use toner. This can reduce some stickiness and absorb faster.
