I will post some of my recipe attempts soon.
This is what's great about making your own:
dirt dirt dirt cheap
you can customize to no end to fit your own needs
you know it is fresh
you can make more of it for cheap, so you can use it all over, not just on your face. What's the point of taking good care of your face if the skin everywhere else gives you away? continued >>
I started using C-serums back in mid-90s with Helena Rubinstein Force C serum which came in 5, 10, 15% ascorbic acid (this product was discontinued several years ago). It was half home-made serum as they sold a serum base and ascorbic acid packed separately for max freshness, you had to mix them before use. I used this product continuously for several years and I think in terms of immediate results vit.C products have the largest impact on my skin. It becomes smooth, bright, pores become tighter etc. I also believe it helped with my acnes scares. Since Force-C serum was discontinued I used different over the counter serums (Neostarta, LRP, Body Shop), but I did not like any of them. The largest problem is that they don't seem to sink into my skin. They stay on top and oxidize and after several hours turn yellow right in fron of my eyes. So I want to use something that penetrates right away. My homemade serum comes closest to what I want C-serum to be.
20 gr L-ascorbic acid
10 gr vodka
10 gr glycerin
several drops vit. E
distilled water enough to fill in 100 ml tinted glass bottle
(To make it less moisturising, use less glycerin. Also, shake it before use to dispense vit. E)
10-20 gr L-ascorbic acid
added to the Body Shop Vit. E or Vit. C facial sprays
The reason I use Body Shop sprays for face is because they contain preservatives and stabilizing agents. However I do not want to use the chemicals all over my body, so I use more simple and less stable preparation for my body.
I make my homemade Vitamin C serum with Solgar Vitamin C crystals, water and glycerin (because Propylene Glycol is hard to get in the UK). I make a 10% version using 1/4 tsp on Vit C, 1 1/2 tsps water and 1/2 tsp glycerin. I store in an amber glass dropper bottle in the fridge and throw it out after one week. I don't know if I've had any effects from it but I'm using it to see long-term results. I splash it on my face and neck after cleansing in the morning and apply moisturizer over it. Then I wait 20 mins and apply a high PPD European sunscreen.
I thought the water-based vit C serum with propylene glycol lasted about a week...so I make new batches weekly:
1/4 tsp l-absorbic acid powder (I like the Vitamin Shoppe brand -- dissolves intantly)
1/8 tsp ferulic acid powder (from skinactives.com)
1/2 tsp propylene glycol
enough distilled water to make 1 oz.
Slight stinging, but goes away quickly. I apply in the morning and then let it absorb for 10-15 minutes (while getting dressed or eating breakfast). Then I apply my sunscreen. I like to think of the vit C serum as the silk underwear of skincare -- just a light layer that makes other stuff more efficient.
