Evening Primrose Oil in Skin Care

Evening primrose oil, (Oenothera biennis), is a common ingredient in many skin care and supplement products.

It contains extremely high amounts of valuable fatty acids such as linoleic, linolenic, and gamma-linolenic fatty acids.

Evening primrose oil is comedogenic, which means it can clog pores and should not be used on acne-prone skin or allergic sensitive skin subtypes.

What is evening primrose oil?

Evening primrose oil is a plant extract used in a variety of products like skin care products and fatty acid supplements.

EPO is considered the best source of gamma linolenic fatty acid out of all oils used in skin care.

EPO contains high concentrations of many useful fatty acids for products like moisturizers, cleansing creams, and various serums.

This oil is has shown significant positive impacts on patients with eczema.

Evening primrose oil is used in skincare because it has extremely high concentrations of anti-inflammatory compounds.

Linoleic and linolenic fatty acids are great in moisturizers and other products meant to soothe inflammation and hydrate skin.

EPO has one of the highest concentrations of linoleic acid of any oil used in skin care at 70%.

EPO fits into the ingredient category of "dry oils" because linoleic fatty acids are unsaturated fats.

It serves a similar function to sunflower oil products in skin care, but with a lower concentration of oleic acid than sunflower oil has.

Evening primrose oil products

Evening primrose oil has an extremely high concentration of beneficial and soothing unsaturated fatty acids for skin care, like linoleic, linolenic, and gamma-linoleic fatty acids,

It is used as an ingredient in many kinds of skin care products such as:

Evening primrose oil is a tyrosinase inhibitor.

Tyrosinase inhibitors block tyrosinase receptors to stop them from producing melanin, or skin pigment.

Evening primrose oil is one of many skin lightening ingredients used in skin care.

It can be used alongside other tyrosinase inhibitors like hexylresorcinol, as well as PAR-2 blockers like niacinamide.

The best combination of skin care products for you depends on your custom skin care routine.

Shop for skin lighteners by your Baumann Skin Type to make sure you only use the right oils for your skin.

Retinoids

Using evening primrose oil with retinoids for wrinkles

Evening primrose oil will not fix wrinkles on skin on its own, but it can be used alongside a retinoid as part of an anti aging regimen.

Evening primrose oil is used alongside retinoids and other anti-aging ingredients in many products because of its soothing linoleic fatty acids which counteract the side effects of retinoids.

Retinoid routines vary greatly based on your skin type and personal skin issues. Be sure to take the Baumann Skin Type questionnaire to develop your custom skin care regimen!

Hormones and evening primrose oil

Evening primrose oil products can affect your hormones when taken orally.

When used in topical skin care products, EPO does not have any effect on hormone balance.

It contains extremely high levels of beneficial fatty acids that have been shown to have many interesting positive effects on hormone balance.

For example, evening primrose oil supplements have been shown to improve reproductive hormone regulation in obese rats. (1)

Though more testing is required, it seems that EPO might one day be commonly recommended for regulating reproductive hormonal imbalances related to obesity in humans.

EPO affected levels of follicle stimulating, luteinizing, and testosterone hormones, reducing the complications from hormonal changes in polycystic ovary syndrome. (2)

In this same study, EPO reduced insulin and serum glucose levels and increased insulin sensitivity - all of which are beneficial effects.

Metabolic processes having to do with the reproductive cycles were clearly improved as compared to the control group in this study.

Can you use evening primrose oil topically?

Yes, EPO oil can be used topically, and is found in many topical skin care products.

It is very anti-inflammatory because of its high linoleic acid concentration.

It also contains healthy omega-3 fatty acids, an important nutrient that is not naturally synthesized in the body.

Evening primrose oil is used in topical products to hydrate skin, repair the skin barrier, and soothe inflammation.

It is also an occlusive ingredient that helps hold water into the kin and protect the skin from allergens and irritants.

There are conflicting reports on the hormonal impacts of EPO, some studies have noted changes in pregnancy related hormones in obese rats when exposed to EPO through oral ingestion. (1)

When used in topical applications for skin care, EPO has shown no evidence of altering hormone production in any way. 

It is worth asking an endocrinologist or your dermatologist if EPO is right for you if you are planning a pregnancy, are pregnant, or have hormonal imbalance.

EPO does not have any dangerous side effects when used in skin care products.

As with many oils in skin care, over application can lead to clogged pores or an undesirable film on the skin.

EPO is comedogenic, meaning it poses a risk of clogging pores in acne prone or sensitive skin subtypes.

EPO might be useful regulating hormones required for healthy normal gestation in obese populations

Some sources claim that EPO should be altogether avoided during pregnancy, so consult your OB/GYN if you have any concerns. (5)
