I can’t guess the structure of a chemical (or mix of chemicals) from a name like saccharide isomerate. This name means (sort of) sugars that have been modified in such a way that they become different sugars. Uh? However, saccharide isomerate is sold in the skin care industry as a glycerin alternative and is used in many skin care products. Why not use glycerin? Maybe saccharide isomerate is cheaper,or easier to use, I don’t know, but I like my ingredients to have a chemical structure I can recognize. In any case, you should not use sugars “just because”. Why? Protein glycosylation is why the skin of people with diabetes ages…

Yes, they can both be true. If there was ever an example of why you should not have “absolute”preferences (be dogmatic about a subject), this is it. I have posted a lot about natural vs. synthetic chemicals in skin care that you may wonder if I have anything new to say. I think I do. It is unlikely that a natural chemical will be bad for you, unless they are trying to sell you a poisonous plant extract like Nerium oleander as skin care (!). This does not happen very often simply because there are not that many silly people willing to spend money on a poison. Case 1) Natural…

Two products, not counting those for eyelashes and eye brows. As always for Skin Actives, look at the ingredient list. First, let me tell you about some of the ways that eyes are special. We have to be careful not to irritate them and be very careful not to increase the chances of getting an eye infection. Styes, infections in the eyelids, are also very uncomfortable. Also, the skin of the eyelids and in the eye area is thin and gets thinner with age, making what happens in the capillaries below very visible. Eyes, like the lungs, are open to the environment and exposed to pollutants and irritants. What do…

Lazy is not bad unless you are repeating old formulas that everybody knows don’t work. To those who think that foreign companies make better skin care products, here comes a warning: Babor, is a German company that uses very American run-of-the-mill ingredients to sell products with huge mark-ups. Here, again, the brand value is in the ridiculously high price; it is certainly not in the quality of the ingredients. Another irritating fact: they baptize old, inexpensive ingredients with novelty names and then they leave you to try to guess which ingredient is which. Maybe it doesn’t matter? Here are some examples: “Telovitin, extends the life cycle of skin cells. Agicyl,…

Argan oil is extracted from the seeds of the fruit of the argan tree (Argania spinosa). The fruit takes a long time to mature and is not really edible, it is used as animal feed. Everything in the fruit is used: the peel and pulp of the fruit for animal feed, and the same for the paste that remains of the kernel after the oil is extracted by pressing. The nut inside the fruit contains one (occasionally two or three) small, oil-rich seeds; the oil is pressed from these seeds. The method used to extract the oil depends on what is available. Using stones is the most basic method. The…

How much is too much? The answer to this apparently simple question is very complicated: as complicated as the number of ingredients used in skin care. Also, for a good answer, you may have to go to numbers that are much smaller than a percent (1%) and go to parts per million. In the best of cases more is likely to be a waste of money. You are throwing away the money you spent on the active by trying to add more. For example, if you add more ascorbic acid to a serum than will possibly dissolve (as determined by the laws of nature and how water interacts with ascorbic…

In April 2017, we offered a limited run of our Hyaluronic Acid Serum with EGF as a Bonus and we received tons of great feedback. Although we are unable to add this to our line-up of great products, we think you’ll find that it’s super easy to make for yourself! If you are just looking for an anti-aging product that contains both Hyaluronic Acid and Epidermal Growth Factor (EGF), then we still recommend our Collagen Serum. Collagen Serum is our best anti-aging product and contains these ingredients and many more to help promote healthy skin. However, those of you who are looking for a light, water-based moisturizing serum with some added benefits should look no further. All of…

Copper is present in our water and air. Depending on how old is your house, there may be too much copper in your water. Depending on where you live, there may be too much copper in your air. But we need copper for good health. How much? We have very important enzymes that depend on copper for activity: cytochrome oxidase, copper/zinc superoxide dismutase, tyrosinase and more. Why is copper so important in these enzymes? Because of its capacity to take and donate electrons. Tyrosinase, for example, is an oxidase that we need to make melanin, the skin and hair pigment. For people who are trying to lighten their skin, or…

Why I love apocynin, tonic for our skin stem cells. You will love it too! First of all, I like it because it is old. Apocynin is as old as the plants that make it, and they are many of them. Even its health promoting properties have been known for quite a while. Old means that we know more of its tricks, its benefits and that it is OK for humans to use it. Second of all, I like it because it has anti-inflammatory activity. Extracts containing apocynin have been used for centuries to help with asthma and heart problems. Purified by Schmiedeberg in 1883 from Canadian hemp, its chemical…

Skin Actives makes it easy to avoid the few products we make that contain ingredients not suitable for vegans. In the past, skin care companies used a few animal sourced ingredients. One example would be extracts from cow organs used because of their high content of epidermal growth factor. This sourcing was never made evident in the ingredient lists. Another if the use of growth medium that contains fetal cow or horse serum, again because of the presence of growth factors that cells in culture require to grow and divide. This source is not disclosed in ingredient list, as the name used is “human fibroblast conditioned growth medium”. Unless you…

You will find Centella asiatica extract in several Skin Actives products, including the capillary health cream, restoration cream, scar vanishing gel , ultra calming cream, and antiaging cream. We also sell it as a Do It Yourself (DIY) ingredient. As you can see, it is a favorite active that we have been using since we started Skin Actives. Centella asiatica (Gotu kola, a.k.a. Hydrocotyle asiatica). This oriental herb has been used for centuries in both traditional Chinese and Indian medicine. The active chemicals in the extract are terpenoids including asiatic acid, madecassic acid, and asiaticoside. Centella asiatica promotes wound healing, apparently by stimulating the production of type I collagen and…

You’d better rethink that. Sulfate is just one of the ways that life forms, including us, take sulfur from the environment. You may have a bad feeling about sulfur if you live near a volcano which emits sulfur smelling gases. If you also believe in the existence of the devil and the underworld, you may associate the smell of sulfur to bad stuff or the Holemouth of Buffy . On the other hand, if you work in a laboratory that has drain problems (old Michigan State Biochem lab!) then the smell of hydrogen sulfide may warn you that you have to pay attention to the drains (hint: keep sinks wet).…

Zinc PCA is the Zinc salt of pyrrolidone carboxylic acid. It helps control acne and decrease sebum secretion while helping the skin retain its humidity. The mechanism of action of Zinc on acne may still be a matter of discussion, but there seems to be an agreement that salts of this metal decrease inflammation caused by acne, perhaps through inhibition of the enzyme that catalyses the production of dihydroxytestosterone, a hormone that controls sebaceous gland activity. Zinc is also an antibacterial, and its salts are used to control dandruff. At Skin Actives we decided to offer zinc as zinc PCA. Pyrrolidone carboxylic acid, PCA, also called L-pyroglutamate, is a derivative…

Kojic acid dipalmitate is a derivative of kojic acid and a fatty acid (palmitic acid), and one of the many active we use to alleviate the problem of hyperpigmentation. Sometime ago, may be our skin was uniformly pigmented, but as soon as we got our first suntan, that perfection was gone. Small areas appeared that were more heavily pigmented than others. Why? Because synthesis and accumulation of melanin in the skin is an exquisitely complicated mechanism which is easily disrupted. When disrupted, hyperpigmentation ensues. There are many ingredients that can be used to help with hyperpigmentation and this is a good example of when not to go for harsh “treatments”.…

For many reasons but I will try to keep it short. EGF is a most important ingredient when it comes to skin health. It signals for healing, cellular division and increased protein synthesis (among other benefits). We need it. EGF goes down as we age, like many other cell functions, but when you apply it to the skin it signals for generalized increased skin activity, rather than stimulation to make more of a single protein. Everybody knew how valuable this growth factor was since the 1960s when growth factors were discovered. See this to find out more about Stanley Cohen. But, EGF was not available just a few years ago.…

Which types of vitamin C products will help your skin Any good product (serum or cream) should give the vitamin C an environment that preserves its structure. Otherwise, an oxidized vitamin C will work against your skin! How? Oxidized ascorbic acid is a pro-oxidant. Just as ascorbic acid can donate electrons to your skin, oxidized ascorbic acid will be hungry for its missing electrons. Copper or iron will promote ascorbic acid oxidation. Unfortunately, this basic fact of life is unknown to some people in the skin care business so you will find this unfortunate combination is some skin “care” products. How does vitamin C work FOR your skin? As a…

There are skin “treatments” that women take because they want to feel good and pampered. Could we please re-examine this idea so that we don’t damage our skin and bodies when we pamper ourselves? I am all for a good massage (not those that leave you hurting) and a yogurt mask while you take a nap on your couch. But, do you know what sonicating does to live cells? In a biochemical lab we use sonication to break cells. Sound waves break cell membranes (all of them). You are not an inert piece of jewelry that needs to be cleaned. Did you know that cascara sagrada (Frangula purshiana), a laxative,…

Sometimes (look at Skin Actives website) there may be two products with similar names, like antioxidant, with one a cream and the other a serum. Is there any reason to have two versions? I know that in the industry, the word serum is used to convey the idea that it has a higher concentration of the magic ingredient. This is not necessarily true. In my case, I use a serum when the ingredients are either water soluble OR oil soluble; and I use a cream when I want to include two types of ingredients, some soluble in water and others in oil. A cream is an emulsion of oil and…
