What Is Borage Seed Oil/Hydrogenated Borage Seed Oil Esters?
Borage seed oil comes from the seeds of Borago officinalis, a hardy herb also called starflower. Rich in gamma linolenic acid and other fatty acids, the oil has long been valued for its soothing feel on skin. To create Borage Seed Oil/Hydrogenated Borage Seed Oil Esters, manufacturers first take the natural oil and fully hydrogenate a separate batch of the same oil, turning its unsaturated fatty acids into saturated ones that are solid at room temperature. They then blend the two through a process called transesterification, which swaps fatty acid groups to form a stable mix of liquid and solid esters. The resulting ingredient keeps the nourishing profile of the original oil but is less greasy, more oxidation resistant and easier to use in modern formulas.
Borage entered skincare in the 1970s when formulators searched for plant oils high in omega-6 fatty acids that could calm dryness. The esterified form gained popularity in the 2000s because it offered the same comfort without the tendency to go rancid. Today you will spot Borage Seed Oil/Hydrogenated Borage Seed Oil Esters in facial and body moisturizers, barrier repair creams, anti-aging serums, overnight masks, lip balms, baby care lotions and after-sun treatments.
Borage Seed Oil/Hydrogenated Borage Seed Oil Esters’s Cosmetic Benefits/Uses
This balanced blend of natural and hydrogenated borage oil provides two main benefits in skincare.
- Emollient: Softens rough patches, fills in tiny gaps between skin cells and leaves a smooth velvety finish that helps other actives spread evenly.
- Skin protecting: Forms a light occlusive layer that slows moisture loss and shields the surface from everyday irritants, supporting a healthy barrier.
Who Can Use Borage Seed Oil/Hydrogenated Borage Seed Oil Esters
This esterified oil suits most skin types including dry, normal, combination, sensitive and mature because it is lightweight yet rich in barrier-supporting fatty acids. Very oily or acne-prone skin may still prefer lighter humectants, but the hydrogenated portion keeps the texture from feeling heavy so many with balanced to slightly oily skin tolerate it well.
The ingredient is entirely plant derived so it is suitable for both vegans and vegetarians.
There is no known issue for women who are pregnant or breastfeeding when the ingredient is used topically in cosmetic amounts. This is not medical advice and anyone who is pregnant or nursing should clear all skincare products with a healthcare professional first just to be safe.
Borage Seed Oil/Hydrogenated Borage Seed Oil Esters does not make skin more sensitive to sunlight so no special daytime precautions are needed beyond regular sunscreen use.
Potential Side Effects/Adverse Reactions

- Mild redness or stinging on very sensitive skin

If you notice any irritation or other negative change in your skin stop using the product and seek medical advice if needed.
Comedogenic Rating
Rating: 2/5
The base borage oil sits around a 2 on the comedogenic scale and the hydrogenated portion plus transesterification slightly reduce its tendency to clog because the resulting esters are lighter and more stable. Still, its blend of fatty acids can occasionally settle into pores on very oily or congestion-prone skin, so it cannot be called fully non-comedogenic.
Most users with normal, dry or even mildly oily skin will have no issues but those who break out easily may want to monitor how their skin responds.
Formulation matters: when combined with lightweight humectants and good emulsifiers the risk of pore blockage drops further.
Summary
Borage Seed Oil/Hydrogenated Borage Seed Oil Esters works primarily as an emollient and skin protectant. Its fatty acids smooth rough texture while the hydrogenated esters create a breathable film that locks in moisture and shields against irritants.
The ingredient enjoys steady popularity in barrier creams, baby lotions and overnight masks because it delivers the comfort of a natural oil without the greasiness or short shelf life. It is not as trendy as argan or jojoba yet formulators appreciate its balance of feel, stability and omega-rich profile.
Topically it is considered very safe with low rates of irritation or sensitization. As with any new skincare product it is wise to patch test first to make sure your skin agrees with the formula.
