| I found this article http://www.ncbi.nlm.nih.gov/pubmed/9256916on citric acid. Does anyone use it in concoctions or ready mades for anything other than ph adjustment? From this article I should think there is a certain value in it for skin care, but haven't found much else about this. |

It is from wiki but here goes:
Cosmetics and pharmaceuticals
Citric acid is widely used as a pH adjusting agent in creams and gels of all kinds. In this role it is classified in most jurisdictions as a processing aid and so does not need to be listed on ingredient lists. Citric acid is an alpha hydroxy acid and used as an active ingredient in chemical peels.
Citric acid is commonly used as a buffer to increase the solubility of brown heroin. Single-use citric acid sachets have been used as an inducement to get heroin users to exchange their dirty needles for clean needles in an attempt to decrease the spread of AIDS and hepatitis.[12] Other acidifiers used for brown heroin are ascorbic acid, acetic acid, and lactic acid; in their absence, a drug user will often substitute lemon juice or vinegar.
Citric acid is used as one of the active ingredients in the production of antiviral tissues.[13]

I only use it as a pH adjuster when necessary mainly since I do use LAA, RA and Glycolic acids. |

 Strange, from what the link I posted states I should think citric acid would be a nice ingredient in skin care. I found another reference to the same study (but on a blog, nothing scientific), and I quote:
| Quote: |
In one study, American researchers investigated the effects of a 20% citric acid lotion on skin thickness and GAG content in sun-damaged skin. They recruited six female volunteers (aged 70-83) who had clinical evidence of sun damage, including fine wrinkling and alterations in pigmentation, on their forearms. Using a randomized, placebo-controlled, double-blind protocol, the women’s forearms were treated with lotion that either did or did not contain the citric acid. The lotion was applied twice daily for three months, after which biopsy specimens were taken from the center of the treated area and analyzed.
In the citric acid-treated skin, there was a dramatic increase (41%) in viable epidermal thickness, i.e., the thickness of the basal cell layer of living cells. At the same time, there was a significant increase (16%) in overall skin thickness. In the dermis, there were also major increases in the levels of two specific types of GAG: hyaluronic acid (up 57%) and chondroitin sulfate (up 66%). GAGs constitute only about 0.1-0.3% of the dry weight of normal dermis, but they have the remarkable property of being able to bind up to 1000 times their own weight in water. Thus, even a relatively small change in the amount of GAGs in the dermis can result in a large increase in its hydration (water content), and this may account for the observed increase in the thickness of the dermis. |
You'd have to admit it SOUNDS pretty interesting! I guess if you use L AA you wouldn't need to try this though. |

My main thinking is between RA, and LAA for collagen, then all three adding in Glycolic Acid I am using enough acids?
You are right it seems as though it would be used for more than peels and pH adjustment? 
Edit To Add:
Maybe I should try a serum made with citric acid on my forearms where thanks to Florida sun I have the worst hyperpigmentation? |

| For me this is a very shocking fact but will now surely try it..... |

| After a bit of googling to see what kind of skin care products with citric acids are about last night, today I made a serum based on one of Kassy's vitamin C recipes. Test driving it on my arm to see if there's any irritation. It's about 10% citric acid and I intend to use it at night. So far the acid arm is still happy. Don't have ph test paper so I don't know how effective the solution is though. |

 Well, that was an experience. Because nothing happened on my arm, I thought I could try it on my face. After half a minute I rinsed it off because it stung, especially on the spot that got burned from a vit. C serum. After that I put some cream on my face to soothe it, and while rubbing in the cream a LOT of dead skin came off. Obviously I don't exfoliate enough.
This is a 10 percent solution and for my skin (not used to anything stronger than yoghurt and lemon juice) its way too strong to use as a serum. I thought I would report this asap, in case anyone else wanted to try it. |

@Lotusesther
Hi, can you tell me what the outcome of your citric acid experiment was? Im also interested in making citric acid serum. |

| The outcome was, that I will not do this again. |
