| What is it? | A carrier oil pressed from the seeds of the borage flower. It is primarily comprised of linoleic and γ–linolenic acid. |
| INCI | Borago Officinalis Seed Oil |
| Appearance | Pale yellow liquid oil |
| Usage rate | Up to 100% |
| Texture | A thick, heavy oil |
| Scent | It smells very distinctly oily/fishy; I recommend blending it with other carrier oils and perhaps some essential oils to dilute/mask the scent. |
| Absorbency Speed | Slow |
| Solubility | Oil |
| Why do we use it in formulations? | Borage oil is recommended for acne-prone, mature, dry, and/or sensitive skin. |
| Do you need it? | No, but it is useful to have one of either Evening Primrose, Black Currant Seed, or Borage oil. They all have a similar fatty acid profile so there’s no real need to have more than one of them. |
| Refined or unrefined? | I have tried the unrefined stuff and it’s fine, but if you are quite scent sensitive you might prefer to source the refined variety. |
| Strengths | It’s amazing for battling acne and tacking problematic skin. It’s also recommended for aging skin. |
| Weaknesses | It’s pretty heavy and doesn’t smell amazing. |
| Alternatives & Substitutions | Evening primrose and black currant seed oils have a similar fatty acid profile. They are also similarly heavy and oily-smelling. |
| How to Work with It | Include it in the oil phase of your recipes; avoid extended exposure to heat where possible. I typically aim to dilute it with a lighter oil or in an emulsion. |
| Storage & Shelf Life | Stored somewhere cool, dark, and dry, borage oil should last up to two years. I recommend storing it in the fridge. |
| Tips, Tricks, and Quirks | Try blending it with a faster absorbing oil, like argan or pomegranate seed, to help it sink into the skin faster. |
| Recommended starter amount | 100mL (3.3fl oz) or less |
| Where to Buy it | Buy it from an online DIY ingredient supplier or Amazon. |
