We may not like the oiliness that is natural to our skin as teenagers, but it has its advantages. Disadvantages? They are many. The minor one is the look of our oily skin. Shiny and not “glowing”, although it will reflect the light and be as glowing as it can be without Photoshop. Then, the sebum is great food for acne bacteria, and we all know how that goes. But think what your skin looks without sebum, or, rather, just wait until you are 40! As hormone production goes down, sebum will go down too and then dry skin and wrinkles come with it.If you are lucky, acne is long…

Because glutathione protects your skin from strong oxidants! Glutathione is one of the peptides that matter, and a lot. Glutathione is present in us and in most living beings for good reasons. Glutathione helps us cope with life at 21% oxygen (what we do have in the atmosphere). Respiring oxygen allows us get the most energy out of our food but it carries a price: Reactive Oxygen Species (ROS*), What are ROS*? Reactive oxygen containing molecules that are so desperate for electrons that will take them from anything and everything. There goes your DNA, your proteins, your lipids (vital for cell life) etc. In top of the ROS* we produce…

Note that most people use this term for “bumpy” skin, common in children and teenagers. Some types of keratosis pilaris (with longer names) are related to severe genetic problems. Keratosis pilaris is a (usually) temporary disorder of keratinization, The problem resides in the upper portion of the hair follicle, which fills with scales instead of exfoliating normally. In bumpy skin, actives that improve keratinization and skin renewal will help a lot. These include alpha hydroxy acids, salicylic acid (so called “beta hydroxy”), and vitamin A. Other actives that can help are those that will help keep the skin moisturized but will not “plug” pores. K.P. is normal, if we define…

We’ve added a phytic acid to our reformulation of Vitamin C Serum 15%. Phytic acid is used in some alpha hydroxy acid serums because it is a weak acid like ascorbic, malic, etc. Phytic acid is the way we and plants and other organisms store phosphate. Why do we need to store phosphate? Because it is vital for everything that has to do with energy production and use and synthesis of everything that is important to life so it is very useful to have it handy while at the same time without interfering with what is going on at the time. Hence, storing it as phytic acid makes sense. Why…

Deficiency of vitamin C results in scurvy (the name “Ascorbic Acid” is derived from the Latin word for scurvy, scorbutus), a nasty illness whose easy fix, citrus fruit, eluded pirates and sailors until 1753. Why is L-ascorbic acid a vitamin? Most animals can make their own vitamin C, but humans can’t. Somewhere along the line we lost a crucial enzyme, L-gulonolactone oxidase, required for the synthesis of L-ascorbic acid, making it an essential nutrient (i.e. we must get it by eating food containing it, or applying the vitamin to our skin).
