another update: serum

I didn’t use serum while I was away, as I forgot to pack it. I often leave it behind anyway, as I prefer to pack light / minimalist and usually in one carry-on bag (except that if I’m going for more than a week in summer or a couple of weeks in winter, I’ll need to pack a checked bag for the sunscreen supplies).

On my return, I used up the last of my older supplies of Silk Naturals Awesome Sauce vitamin C serum. Good stuff. Will be getting that again.

I had also ordered some more of the ASDM Beverly Hills vitamin C serum online while I was away. Yep, epic vacation fail: didn’t entirely manage to escape the interweb and buying stuff. Bad me. My purchases were awaiting me when I returned home. Which is always nice. As previously, the multiple layers of packaging were insane, but the contents had to be fair been well protected from the elements and all possible perils, and probably also every imaginable threat and a few that would be barely conceivable to the imaginative or maybe even unimaginable. All that was missing was an explosive-proof metal box.

The tail end of one bottle of serum overlapped with the start of another. This enabled some side-by-side testing. Approximate, but still. The two serums are quite different in composition: both contain the magnesium ascorbyl phosphate (MAP) form of vitamin C, but ASDM BH has more of it; both contain extra antioxidants, but different ones; both also contain humectants (ASDM BH has a fair whack of hyaluronic acid, SN has a small quantity of glycerin); both are unscented; both contain some ingredients that might or might not break some people out in spots or irritate. I’ve talked about them previously in other reviews on here, in the main “vitamin c” post series and under “antioxidant serum.”

[UPDATED (2017-07) TO ADD: the cruelty-free status of ASDM BH is uncertain, and they do use animal-sourced ingredients that are by-products of killing animals for meat (emu oil). I haven’t repurchased this serum in a while. But I digress…]

Information source:

Tested split-face and on hands and arms, one serum on each side.


1. Quantity required: about the same to cover the same surface area.

2. Application: both are gels; ASDM BH is now clear, old version was creamy-coloured. The SN is more forgiving if applied to damped skin. With the ASDM BH, skin was sucked dry in instants.

Applied to dryish skin: felt much the same. I then patted on some water; just a couple of drops from the good old tap.

3. Once the hurdle of (2) above had been surmounted, skin feel within the next minute: the same.

4. After ten minutes: slightly moister and plumped-up-er on the ASDM BH side. A more silken skin-feel.

5. After an hour: ditto.

6. I didn’t keep pinching myself all day, because unfortunately I lost focus and got distracted from the important business of skincare testing. By work. Sorry. I know, I know, what can be more important and interesting than blogs and skincare and diarying and self-examination and obsessive self-reporting and all those things that are The Selfie writ large into one’s whole life, lifestyle, and extended beyond oneself into culture and human existence itself, verily and forsooth? It’s way beyond zeitgeist, man.

7. But I did some pinching and punching of myself in the evening. Punishing myself for my failings of earlier. Making up for the pinching I’d missed out on earlier. And the final results?

SN vs ASDM BH: ASDM BH wins on moisture retention.

8. I also experimented, using the vasty swathes of my largest available skin-expanse (thighs), to draw some further comparisons. In all cases, with a layer of oil on top and then sunscreen, to replicate normal daily skin conditions

(a) either of the two serums vs. nothing:
serum wins

(b) either serum vs. layer of dampness (=water from bathroom tap; our water is quite soft–low mineral content–and slightly acidic) on skin:
serum wins

(c) vs. witch-hazel hydrosol (=water-based, steam-distilled, no alcohol):
serum wins

(d) nothing vs. either dampness or WH:
the latter two win

(e) dampness vs. witchery:
plain water wins

9. I’ve previously used other hyaluronic acid serums (not as good as the ASDM BH) and plain glycerin (irritation and spottiness, except in low concentration, when hydrating results are little different from plain WH or water alone). I have also used rosewater and RW-and-glycerin toners, ages ago, that were good. Not for ages though as I can’t stand the smell anywhere within, well, smelling distance or my nose. Which means not using them on my face.

I’ve used various other serums over the last few years. Mostly just testing them out in small quantities, in limited tests (limited by the quantity provided and, all too often, self-limited by reaction). I’ve found some others that were good on the moisture-retaining side: for example, the oat serums from Garden of Wisdom and Silk Naturals. I found both of these to be better than glycerin solutions or more hyaluronicky concoctions.

I’ve also tested out a lot of vitamin C serums. The ASDM BH one and SN Awesome Sauce are the two moistest I’ve used.

10. So here’s a ranking of these various humectant layers, from weakest to strongest:

—witch-hazel hydrosol
—Silk Naturals Awesome Sauce vitamin C serum
—ASDM Beverly Hills vitamin C serum

11. ASDM BH is cheaper, including when you factor in the postage cost to Canada; the same should be true for other countries outside both companies’ homes in the USA. Though it should be noted that shipping worked out much the same for me, as neither order was just one bottle of serum.

12. But: in a drier climate, it may be better to avoid humectants like hyaluronic acid. Also if you don’t have the time or coordination to faff about with an extra layer of dampness to skin between the serum and moisturiser layers. In such circumstances Silk Naturals Awesome Sauce is recommended instead.

The usual caveats apply, as ever. This is my skin. It is dry and dehydrated, thin, reactive; it can be finicky, foolish, frivolous; whimsical. What works on it and how it responds to or reacts (or over-reacts) to anything will not necessarily be the same as what does or doesn’t on your or anyone else’s skin. Whim and whimsy must be taken into consideration, yet cannot be predicted.

Expect the unexpected. Have no expectations. The only exceptions to these rules are those trivial yet cardinal (and I don’t mean serums or any other skincare) trusty reliables in life: a good cup of tea or coffee, a decent glass of something cool, chillaxing sitting on a beach, enjoying sunshine or looking forward to the next glimpse thereof… that sort of thing.
