If the wall in your home has a crack in it, you call a painter. He will patch up the wall, prime it and paint over. The wall will look like new. If your left eyelid is a bit “droopy”, and your first instinct is to see a plastic surgeon, think again. Because your skin is alive and it is silly to think of surgery as the only option. Your skin is not like a wall: your skin is alive and capable of changing for the better. %0, 60 or even 70 does not mean that you have yo give up on skin care, on the contrary. Almost anything good…

Warning: this is a “heavy” post that may feel to you like you are back in school and not in a good way (like for prom). You don’t have to read it but the objective is to convey to you the complexity of skin metabolism and molecular biology and why you should never look for a “magic” ingredient when it comes to skin youth and health. In short, life (LIFE) is complicated. Your skin is alive. Below the few layers of dead cells in the epidermis, perfectly designed for the tough job of protecting your body from pollution and damage, is the basal cell layer. Here is your stem cells…

What is all that noise about ugly masks? A protein or carbohydrate solution in water will dry as a film, tensing your skin and make you look ugly until you rinse it off. Benefits? None. A leave on serum will give more time for any active ingredients to make its way into the skin. Hanacure all-in-one facial ingredients Mask: Water, Carbomer (thickener), Nelumbo Nucifera (Lotus) Leaf Extract, Yeast Beta-Glucan, Caffeine, Niacinamide, Ethyl Ascorbyl Ether, Hovenia Dulcis Fruit Extract, Camellia Sinensis Leaf Extract, Honeysuckle Flower Extract, Rosa Canina Fruit Oil, Peony Root Extract, Sophora Angustifolia Root Extract, Rhus Semilata Gall Extract, Peach Leaf Extract, Ginkgo Biloba Leaf Extract, Caprylyl Glycol, Scutellaria…

Why is it worth your while to make a skin care product yourself? I can see two reasons: 1) When what you want does not exist in the market 2) When what you want does exist but it is too expensive. However, first you should make sure that what you want is what your skin needs, and not something that has been pushed on you by advertising. When not to do DIY 1) Don’t make a product so that you can add to it all the peptides that are in fashion. Why? Because such a product is unlikely to benefit you or your skin. If the ingredients are not beneficial,…

Look at your face and hands and see what last Summer, the one that just ended, did to them. Ouch! Pigmentation is more irregular, plus there is a new scar or two and, how about those new wrinkles? First of all, as the Hitchhiker’s guide to the Galaxy will tell you: Panic is the worst advisor when you have any problem, especially a health problem, panic makes you take bad decisions. My suggestions 1) NOT suitable for sensitive skin: A good start would be a super light “peel”: 15% Vitamin C serum or alpha/beta exfoliator, but not both. More is less, in this case. Follow the instructions carefully. Rinse the…

Remember: All protective mechanisms in the skin are interconnected and regulated by redox-dependent processes. What is glutathione? Figure: glutathione (a.k.a. γ-L-Glutamyl-L-cysteinylglycine), with that all-important SH group. When oxidized, two glutathione molecules are joined together to make a S-S bridge. L-Glutathione (gamma-L-Glutamyl-L-cysteinyl-glycine) is a tripeptide composed of the amino acids L-glutamine, L-cysteine, and glycine. Glutathione is part of the antioxidant defense system of the cell, together with superoxide dismutase, catalase, glutharedoxin, thioredoxin, alpha-D-tocopherol (vitamin E), ascorbic acid (vitamin C), and others. GSH protects cells by neutralizing (i.e., reducing) Reactive Oxygen Radicals (ROS*). This conversion is illustrated by the reduction of peroxides: 2 GSH + R2O2 → GSSG + 2 ROH (R…

Striae distensae or stretch marks are deep scars caused by the skin being stretched beyond its capacity to stretch, followed by ineffective repair of the damage. Latin does not make them any less noticeable. They may start as striae rubra, which are reddish streaks (indicating increased blood flow), and “mature” to as striae alba, which are hypopigmented atrophic bands. Location: abdomen, thighs, breasts, more or less anywhere when the skin was stretched too fast. What you see is skin that has less elasticity, more roughness, and lower dermal density than normal skin. At the molecular level What you see at the molecular level is that in normal skin, dermal collagen…

We need to start with the basics: what is a pore, and why they are so important. There will be some repetition here but I hope our readers will not mind too much. As usual, feel free to skip whatever is too boring, but, hidden within the boring stuff you may find some useful facts you have not heard about in the past. Celebrities’ photos how no pores. This is not because celebrities have no pores but because magazines use Photoshop to a ridiculous extent. Is this a problem? I think it is. False advertising makes women buy products that can’t possibly have the effect advertised, which was obtained with…

Did you see the latest “personalized” Clinique? But the new gimmick takes some chutzpah: 15 products (5×3) is not personalized. What do you get for $39? You get 3.9oz (117mL) of a base cream, lotion or gel, plus 0.1 oz (3mL) of a concentrate that contains some ingredients with undefined anti-aging benefits like caffeine, taurine and whey protein. What’s the problem? I like Clinique moisturizers because they work for very dry skin because they contain mineral oil (you can add this to any base cream for 5 cents, though). But, Clinique has very few actives as such. Its products can moisturize and very little more. For example, Clinique’s concentrate for…

What is dull skin? It depends on who you ask. In my opinion, it is a non-existing skin condition, The opposite of dull skin, however, does exist, on babies and in Photoshopped pictures. The famous “glow” of the actresses photographed in the 1920s was obtained by careful lighting, make up and touch-ups. Photo: the great Greta Garbo. Now we have Photoshop and people still dream of the after-Photoshop skin of Julia Roberts. But remember that before Photoshop, her skin is just like yours and mine. . Photo: Julia Roberts: beautiful with or without Photoshop. What a smile! Incidentally, some insects can actually make light. It is called bioluminscence. The insect…

Combination skin is probably the norm, in the sense that some areas of the skin produce more sebum that others. The so called “T-zone”, includes the forehead, nose, and chin, and tends to be more oily than the rest of the face. As people age, sebum secretion decreases, even in the T-zone. This is the main reason why the incidence of acne also decreases as we age, as the sebum fatty acids is what keeps acne bacteria going. What to do then, if you have combination skin? Just use the same products all over, and reserve some T-zone serum for the area of the forehead, nose and chin, as needed.…

One should think that, as more people use sunscreen, skin cancer incidence would decrease. Actually, the incidence of non-melanoma skin cancer is increasing worldwide despite the increased use of sunscreens. In 2014, the USA Surgeon General estimated that 2.2-5.0 million people were treated annually for basal cell carcinoma and squamous cell carcinoma. Why is there more skin cancer despite the use of sunscreen? I am not epidemiologist (and I have not seen explanations in the literature) but I can think of some reasons. The feeling of invincibility that sunscreen, makes people spend more time in the sun. The average age of the population is increasing. All things being equal, all…

There are several components to this “problem” and you may be able to control on some of them. But first: you have no control on who your ancestors were, so forget about under eye shadows if everybody in your family has them. The shape of the face may cause the light to play a trick. In my case, I am happy to look the way my mum and grandmother looked. Or brown hyperpigmentation of the lower eyelid skin along the shape of the orbital rim. A hint of makeup will fix this “problem”. About the other possible components: Keep away from prostaglandin analogs used by some skin care companies to…

First of all, WHY do you have to use retinoids? Because retinoids will help you with very common problems that everybody will have at one time or another: acne and skin aging (wrinkles, etc.). What retinoids do After retinoic acid enters the cell, it binds to specific nuclear receptors. These “activated” nuclear receptors, in turn, bind to specific regulatory sequences (called retinoic acid response elements) in the DNA inside the nucleus and directly change gene expression of specific genes. Such changes in gene expression translate into changes in the production of proteins, and are responsible for the biological and therapeutic effects of retinoids. Acne and retinoids In the 1970s, retinoic…

T-zone serum is a typical Skin Actives product: complex and different from everything else in the market. The secret is in the ingredients, the way it should be.

It is hard to find a precise definition of sensitive skin, but sensitive skin does exist: more and more people are defining themselves as having sensitive skin, reaching numbers as high as 50%. We may have to re-define normal, because once more than half of us have sensitive skin, this becomes the new normal. Clearly, there must be something that we are doing wrong. In “we” I include people and manufacturers of skin care products. What is “exaggerated” reaction? It can be pain, stinging, dryness, inflammation, redness, reactions to products or environmental conditions that usually are not described as irritating or allergenic. In my opinion, this huge increase of people…

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…

Once upon a time, people thought that disease was (a well deserved) punishment for sins. That was before germ theory of disease, and before Pasteur and vaccinations, but there is still a superstitious bit in us still believes that, especially when it comes to acne. Acne is a complex condition that includes faulty skin keratinization, increased sebum production, and acne bacteria overgrowth, followed by follicular rupture and inflammation. A complex condition will have a complex relationship with your body and the environment. Avoid people who tie acne (or any other health problem) with “morals”. And avoid people who blame you for being sick or have bad skin! Indeed, avoiding bad…
