When and how do I use The Ordinary B Oil?

You can use this in the morning or evening. Apply a couple of drops to the palm of your hands and apply it all over your face. You could use this alone or after your water-based products. If you like to use oil and moisturizer, you can apply this before or mix a few drops in with your moisturizer.

As always, read the label, and patch testing is recommended. Please refer to the official Deciem page for a list of ingredients and instructions.

Rachael Candice is one of the moderators of the Facebook Group and you can find her here on Instagram. I’ve tried every TO oil and heaps of other brands, The Ordinary’s B Oil is my most loved.
I have dry previously dehydrated skin and it is the perfect oil blend, used alone or mixed with a moisturizer to give your skin a deep moisture boost. I no longer buy expensive face masks, I’ll just sleep in two layers of B Oil under moisturizer if my skin needs a little extra TLC.

Love it. Been using it for months now, skin is much more hydrated and plumped. Great product, great price. Definitely recommend!

I love this one! It feels like it´s helped my acne heal faster and it is super lightweight too.

Love it! Very good even for my oily skin.

Hated the smell but other than that it works ok. It´s not my favourite.

Can’t use any oils. The Ordinary line is AMAZING.

I have combination skin with dehydration. I use a water-based hydrating serum first, then the oil, and finish with moisturizer and SPF. It’s been the best thing to use on my nose during my cold. No stinging or irritation and prevented broken skin.

Got it as soon as it came out and I love it. It goes on this dry face daily my B…beautiful oil!


Can I use The Ordinary B Oil after The Ordinary Hyaluronic Acid 2%+B5? Yes, you may use them together.

Should we use “B” Oil before or after moisturizer? “B” Oil can be used on its own, or before your cream moisturizer. You can also mix 1-3 drops into your moisturizer. 

Can “B” Oil be used for fungal acne? It can be, but please note that none of our products can be considered medical treatments for fungal acne, so we suggest consulting with your physician to see what may work best for your skin.

Can you please tell me why one might choose B Oil over the Rose Hip Oil or vice versa? Trying to pick between the two right now! Rose Hip Seed Oil would be a great choice if you are concerned with anti-ageing. B Oil is a great choice for overall hydration.

Is “B” Oil suitable in pregnancy? Also, do you have a guide on which products should not be used in pregnancy? While each ingredient has been tested and is considered safe for topical application, DECIEM products have not been tested on pregnant or breastfeeding women. When pregnant or breastfeeding, it is recommended to avoid any skincare products containing retinoids such as formulations with Granactive Retinoid or Retinol. We also recommend not using any of our supplements while pregnant or breastfeeding. Please kindly consult with your physician before using any of our products as all our ingredients are listed on our website. 

More Faqs

My The Ordinary “B” Oil is not green at all. It´s more like a dark orange/brown color. This is a stylized photo. The colour of your product will not reflect the colour in the photo. If your product has a slight green hue, that is normal 

Can I use “B” Oil as a hair oil? If you’d like to, yes you can. Alternatively, we’d recommend exploring The Ordinary 100% Plant-Derived Hemi-Squalane or The Ordinary 100% Organic Cold-Pressed Moroccan Argan Oil 

Can I combine this B Oil with your Buffet serum? We’d recommend layering rather than mixing the two together, ideally.

Would B Oil be ok to use on skin that is prone to getting clogged pores? We specifically avoid comedogenic ingredients.
