Yes it can but it's a super concentrated & powerful oil so remember a little goes a long way and every day is not necessary for all skin types.
We have found that applying the oil in the evening is best - this is when the skin is free from pollution irritants, weather fluctuations, make-up and spf for example. It is the perfect time to nourish and repair the skin with the Rosehip Oil.
If you do apply it in the daytime, just 1-2 drops is needed and we recommend combining with your Day Cream and applying an SPF over the top.
Can it be used for teenage skin? Yes, it's great for acne scarring in particular at this stage. However, as above, it's a very powerful oil and younger skin needs even less than adult skin. Start by using 1-2 drops once or twice a week and only increase if the skin is reacting well.
