How should I safely dilute and mix this oil into my existing skincare products?

Since Medikomed Barberry Aromatic Oil is a concentrated fragrance product, it must never be applied directly to the skin in its pure form. To use it effectively, you should integrate it into a "carrier" base, such as an unscented body lotion, cream, or vegetable-based massage oil. For a standard 50ml container of cream, starting with just 2 to 4 drops is usually sufficient to impart a delicate floral scent without overwhelming the original formula. If you prefer to scent your products on a per-use basis, one single drop mixed thoroughly into a palm-sized amount of lotion is the recommended limit.

When adding the oil to a bath, it is more effective to mix the drops into a dispersant first—such as a tablespoon of sea salt, honey, or a small amount of milk—before pouring it into the water. This prevents the oil from simply floating on the surface in concentrated droplets and ensures the aroma is distributed evenly through the steam. Because everyone's skin chemistry is different, it is important to perform a patch test: apply a small amount of your diluted mixture to the inner forearm and wait 24 hours to check for any signs of sensitivity. If you have chronic skin conditions, are pregnant, or are breastfeeding, consult a specialist before adding aromatic oils to your routine.
