Hi, you can use tea tree oil, lavender oil or even orange oil in your skincare. The only thing you need to keep in mind is that don't apply essential oils directly on skin. You need to mix it with some carrier oil or cream or face wash and then use. You can try essential oils from Anveya.

I would suggest you to checkout Anveya. They have great collections of good quality and pure essential oils.

Any organic oils like almond, lavender , rose which can be applicable for your skin
