The peach tree can reach a height of up to 8 m and has leaves alternately arranged on straight branches. The leaves are divided into petioles and blades. In Central Europe, the flowering season of the tree begins in April. Its flowers are pink or reddish-violet and sit individually or in pairs on the branches, each consisting of five sepals and petals. There is a wide variety of fruit types to distinguish. There are white and yellow fleshy variants as well as early and late ripening strains. The peach has a pale green or yellow, on the sunny side reddish colored fruit skin, which is velvety hairy. The flesh is juicy and pale green or orange. The light brownstone seeds are up to about 4 cm long and 2.5 cm wide. They have an ovoid, pointed shape and are deeply furrowed. The brown seed, which contains 30-45% fatty oil, lies inside the thick stone.

Extraction of peach kernel oil

The light to golden yellow peach oil is acquired from the seeds of the peach kernels. To obtain the oil, the wooden peels of the fruit are removed, the kernels are divided and the oil is extracted with the help of a solvent (e.g. petroleum ether). The oil can also be obtained by cold pressing the seeds of the peach kernels and is usually filtered or refined afterward.

Cosmetic use of peach kernel oil

The oil is quickly absorbed by the skin, leaving a soft and pleasant feeling. The oil can be used in all cosmetic formulas. Due to its ability to bind moisture, it can protect the skin from dehydration, which makes it particularly suitable for the care of dry, flaky skin but can also help with poorly circulated skin. The oil also improves the skin’s barrier function and makes the skin elastic. This helps to prevent the formation of lines and wrinkles.

Internal use of peach kernel oil

One study found that the physical development before puberty of female rats was prevented to a certain extent by injected peach kernel oil.

However, peach kernel oil is considered a healthy oil with regard to blood pressure and heart disease due to its low cholesterol content and can therefore be used in the food industry.

Buy peach kernel oil – what to consider?

As already mentioned, peach kernel oil can be obtained by cold pressing and is then usually filtered or refined. If you want to buy cold-pressed peach kernel oil, you have to dig a little deeper into your pocket, since it is a real rarity in this quality.


When buying peach kernel oil, you should also make sure that it is of organic quality, since peaches unfortunately belong to the fruits that are often contaminated with harmful substances.

Employees of Greenpeace had peaches and nectarines from France, Italy, Greece and Spain tested. Only one out of 32 samples was free of peticide residue. In the other samples, a total of 23 different pesticides were identified, including dangerous carcinogens and nerve toxins.

In order to be sure you avoid residues of pesticides, you should use organic peach kernel oils. These are regularly tested for purity and the risk of unpleasant components contained is very low. This is important because especially oil is a good carrier for pesticides and hormone-like substances, since it transports them well through the skin.
