Mum, look what I made!- DIY 5% Niacinamide, 3% Glucosamine and green tea serum



I’ve been wanting to make this serum for awhile, after reading much discussion from other DIYers on http://www.skincaretalk.com/ and http://www.essentialdayspa.com/ on the wonders of  B3 + NAG (N-Acetyl Glucosamine).

There are a few different recipes posted on the above forums, but it took me a little while to decide what I wanted out of this serum- main purposes, combination of actives, feel on skin, etc. And then there was the looooong wait for my raw ingredients to arrive from the US.


The Recipe:

5% Niacinamide (B3)
3% N-Acetyl Glucosamine

2.5% Panthenol (B5)
9% Green Tea Extract (liquid)
40% aloe vera gel (99.9% from Garden of Wisdom)
10% seamollient (liquid algae extract)
30% Hyaluronic Acid serum (1% premade)
0.5% Optiphen preservative

(note: I used the maximum recommended concentration of actives ingredients) You end up with a gel consistency serum that has a pretty silky feel (I had to play around a bit to get the texture right so that it wasn’t sticky and not too thin)

At the moment I like layering my night time skin care, so I apply this after a shower, apply a moisturiser on top, then massage a treatment oil to seal it all in (I’m using my Marie Veronique Anti Aging Oil+, which I review here) As with all my DIY skin care products, I’m always experimenting with new ingredients with each new batch, so I’ll see how this batch goes for the next 2 weeks and probably play around with tweaking percentages and/or adding new ingredients. ?

Why Niacinamide and NAG?


Topical application of niacinamide has been shown to increase ceramide levels in the skin (our skin’s own emollient), significantly reduce water loss from the skin (2% Niacinamide is more effective than petrolatum in reducing water loss), thus boosting skin hydration from inside out. 

Niacinamide is also one of the few effective non-hydroquinone treatments for hyperpigmentation which is great for overall brightening, and fading/preventing freckles and melasma spots. *Woot*

There are also studies that show that it reduces red blotchiness, sallowness, fine lines, and is 4% is comparable to (the acne medication) Clindamycin in treating acne.

Glucosamine also has anti-inflammatory, brightening, and hydrating properties. Glucosamine and Niacinamide work synergistically to boost hyaluronic acid levels in the skin and increase collagen production.
Olay Regenerist products are based around the Niacinamide and NAG combo, although I don’t think they list the concentration of these actives. If you’re not partial to DIYing your skin care this is another option (I haven’t tried this line of products so let me know if you like this).
