Keep your religion separate from your purchasing, especially of skincare products. There is no Saint Jane in the Christian list of saints, but my Yiddish name is Jane (pronounced Chane and named after my grandmother), so I feel very protective of the name. So when I saw that there is now a skincare brand named Saint Jane, I became interested. Like, taking my grandmother’s name in vain! I found it in Credo, a website that purports to keep your skincare as pure as your heart (Credo in Spanish means religion). Too much religion here in products that should be “ruled” by science. Indeed, in TikTok they use the phrase “sent…

“Nona” from Latin, having nine (remember hexagon, heptagon, etc.?). Is a nonapeptide better than an octapeptide? Or than a decapeptide? It doesn’t matter how many amino acids; the sequence is what matters. In this case, the stereospecificity also matters because a couple of amino acids used in this particular peptide are not present in proteins, which are all Levo amino acids. The actual sequence of this nonapeptide, described by Jayawickreme et al. (1994), is Met-Pro-D-Phe-Arg-D-Trp-Phe-Lys-Pro-Val-NH2Why does it matter? Because it has to do with a spatial 3-D structure that will bind to the hormone receptor, blocking access to the normal hormone and preventing it from working. The idea is to…

This case is about a new skincare brand created in Spain by a plastic surgeon who is telling Spaniards that it’s not necessary to go under the (his) knife to have a young face. All they need is his new line of skincare products. What’s this all about? His theory is that skin ages because of the accumulation of a toxic protein, called “progerin” that causes all the symptoms of aging skin, including thin skin, wrinkles, non-uniform pigmentation, enlarged pores, etc. He then asserts that his new skincare products, containing an alga extract, plus two other plant extracts, can destroy this toxic protein and restore skin to its younger appearance…

Anti-fatigue cosmetics will not make up for lack of sleep. A concealer could help hide the deep shadows under your eyes but otherwise, what on earth are anti-fatigue cosmetics?

Water is good (and cheap). Glycerol is great at moisturizing. Denatured alcohol?…

How do you end up with silly formulations like Perricone’s Hyaluronic 4 + 2 Complex? Ingredients: Water, Sodium Hyaluronate Crosspolymer, Sodium Hyaluronate, Sodium Acetylated Hyaluronate, Hydrolyzed Sodium Hyaluronate, Pentylene Glycol, Ethylhexylglycerin. This ingredient list is silly. Why? There is sodium hyaluronate (hyaluronan), an ingredient we use in Skin Actives. As you can see below, I am against using three of the four actives: Sodium Hyaluronate Crosspolymer, Sodium Acetylated Hyaluronate, and Hydrolyzed Sodium Hyaluronate. The rest is water (solvent) and preservatives. One of these, sodium acetylated hyaluronate, was designed to be used in implants and grafts. It is made by cutting hyaluronan and acetylating it by chemical means, to prevent degradation…

But first, what’s in it? What can it do for you? The ingredient list wants to convey “natural” and “plum” (just because plum and plump together sound like fun), so you will find many label value ingredients below the 1% concentration, which is the boundary after which you can list the ingredients in any order. This is a good way to hide preservatives, but here there are a couple at the end of the list (Sodium Benzoate, Phenoxyethanol). Plums are a type of fruit of the genus Prunus, but this product uses fruits that may look like plums but belong to many different, unrelated species. There are some nice ingredients…

How to start?Buy some self-stick labels and write with a golden marker the following: Magic! Elixir! Golden! Crystal! You are halfway there. Next, I will tell you how to make your own, improved version. Ignore ingredients labeled by me as “label value”, LV. They are there to “plump” the ingredient list and help hide synthetic ingredients and fragrances. Charlotte’s Magic Cream | Charlotte Tilbury Ingredients: Water (solvent), Homosalate (chemical UV filter)), Glyceryl Stearate SE (lubricant), Ethylhexyl Salicylate (exfoliant), Butylene Glycol (solvent), Glycerin (humectant), Butyl Methoxydibenzoylmethane (chemical UV filter), Octocrylene (chemical UV filter), Cetyl Alcohol (emulsifier), C12-15 Alkyl Benzoate (emollient), Cyclopentasiloxane (silicone, feel), Dimethicone (silicone, feel), Phenoxyethanol (preservative), Butyrospermum Parkii (Shea)…

Is the skin of Korean women “better”? If it is, is it because (as “they” say) a Korean beauty routine comprises 20 or so steps? Is it better because they use Korean made skincare? Will Korean skincare make your skin smooth and healthy like that of Korean women? Acne Too many questions. In any case, from what I know, the skin of Korean women is more similar to American skin than it is different. For example, Korean women also get acne, and the acne triggers seem to be the same as for women in the USA: psychological stress, lack of sleep, menstruation, smoking, drinking. And acne is also triggered by…

A product from Spain with a Japanese name. What could go wrong? Just as fake as its Japanese sounding name, here are the ingredients Water, Butylene Glycol, Propylene Glycol, Ascorbic Acid, Glycerin, Glycosaminoglycans, Tocopheryl Acetate, Peg-35 Castor Oil, Benzyl Alcohol, Glycogen, Salicylic Acid, Potassium Sorbate, Sodium Benzoate, Soluble Proteoglycan, Sorbic Acid, Camellia Sinensis (Tea) Leaf Extract, Matcha Tea. Is there anything interesting in this list? Not the solvents (water, butylene glycol, propylene glycol), or ascorbic acid, which will be an oxidizer by the time it reaches your skin. The preservatives, potassium sorbate, sorbic acid and sodium benzoate, are not very interesting either. Glycosaminoglycans (GAGs) or mucopolysaccharides, can be more interesting.…

Like in this cream, where C12-15 Alkyl Benzoate and Polyester 7 are transformed into MAGIC by paying celebrities to advertise it. Pity there is no money left for ingredients like epidermal growth factor and that some many fragrances (Linalool, Citronellol, Geraniol) are likely to irritate your skin. Still, “Charlotte Tilbury” sounds posh, right? Water, C12-15 Alkyl Benzoate, Glyceryl Stearate Se, Butylene Glycol, Glycerin, Vegetable Oil, Isononyl Isononanoate, Cetyl Alcohol, Ethylhexyl Palmitate, Cyclopentasiloxane, Dimethicone, Polyester-7, Phenoxyethanol, Neopentyl Glycol Diheptanoate, Shea Butter, Steareth-21, Oat Kernel Extract, Carbomer, Dimethiconol, Potassium Cetyl Phosphate, Chlorphenesin, Caprylyl Glycol, Xanthan Gum, Hydrolyzed Viola Tricolor Extract, Allantoin, Aloe Vera Leaf Juice, Disodium Edta, Tocopheryl Acetate, Camellia Oleifera Seed…

Ingredients: Distilled Water, Glycolic Acid, Witch Hazel, Sodium Hydroxide, Polysorbate 20, Propanediol, Vegetable Glycerin, Vitamin B5, Calendula Extract, Green Tea Extract, Allantoin, Menthol, Eucalyptus Oil, Spearmint Oil, Vitamin E, l-Ascorbyl Palmitate (Vitamin C), Diazolidinyl Urea, Iodopropynyl Butylcarbamate. They are selling you an acid but they are giving you salt. What a rubbish product! It will irritate because of the eucalyptus, not “peeling” because the glycolic acid is neutralized, menthol to make you think something is happening. Plus the name suggests that it’s a prescription medication. All of the sins of bad skincare in just one product.

Water, Pentylene Glycol, Glycerin, Vegetable Collagen, Amla Extract, Palmitoyl Tripeptide-37, Tripeptide-29, Fucus Vesiculosus Extract, Pichia Ferment Lysate Filtrate, Grape Seed Extract, Kiwi Fruit Water, Coffee Seed Oil, Sodium Hyaluronate, Jojoba Seed Extract, Epilobium Angustifolium Flower/Leaf/Stem Extract, Leuconostoc/Radish Root Ferment Filtrate, Hydroxyacetophenone, Hydroxyethylcellulose, Butylene Glycol. No, vegan collagen doesn’t exist. Don’t waste your money on products that sell you what doesn’t exist. Feeling indignant is the right reaction to this kind of stuff. Somebody called this kind of stuff “the bastardization of science”, to what I answer: aren’t scientists cheap? If you can’t be a serious, honest scientist, please find yourself a different profession. Maybe sell used cars? Or bridges?…

I love L’Occitane. But once I read the ingredient lists, it becomes clear to me that I like the idea of L’Occitania: a romantic part of France, Provence, that I haven’t visited (yet), where a strange language was spoken, it makes me dream of exotic fragrances. But it’s just an idea, crystallized in products that are made of the same ingredients, synthetic fragrances, and colors used by everybody else including Korean and French, and American skincare companies. Artists put together the colors and pictures that make me want to buy a $8.50 soap (3.5oz) or spend $34 in 2.5 oz of water, glycerin, cetearyl alcohol, etc. If I am this…
