>> It's 2 days after Christmas, too early to know the impact of the purchases made based on what AI recommended, either positive or negative.

No worries, I can tell you what to expect: nothing. No effect. Zilch. Nada. Zero. Those beauty creams are just a total scam and that's obvious from the fact they're targetted just as well to women who don't need them (young, good skin) as to ones who do (older, bad skin).

About the only thing the beauty industry has figured out really works in the last five or six decades is Tretinoin, but you can use that on its own. Yet it's sold as one component in creams with a dozen others, that do nothing. Except make you spend money.

Forgot to say: you can buy Tretinoin at the pharmacy, over the counter even depending on where you are. They sell it as a treatment for acne. It's also shown to reduce wrinkles in RCTs [1]. It's dirt cheap and you absolutely don't need to buy it as a beauty cream and pay ten times the price.

It's a teratogen causing birth defects and miscarriages, so severe that "women of child bearing age taking isotretinoin are required to register for the iPLEDGE program. The iPLEDGE program requires that women taking isotretinoin undergo frequent pregnancy tests and commit to using two (2) forms of birth control in order to prevent themselves from getting pregnant."[1]

From Wikipedia[2]: "Isotretinoin is a teratogen; there is about a 20–35% risk for congenital defects in infants exposed to the drug in utero, and about 30–60% of children exposed to isotretinoin prenatally have been reported to show neurocognitive impairment".

See also pages like r/AccutaneRecovery[3] for people harmed by using it for acne, reporting systemic damage, perhaps permanent damage.

Scroll down[1] for the picture of some of the possible side effects of oral Accutane/Isotretinoin on the mother[3] and note that Wikipedia says "the most common adverse effects are dry lips (cheilitis), dry and fragile skin (xeroderma), dry eyes[8] and an increased susceptibility to sunburn" and wonder how a beauty treatment which improves skin condition has most common side effects which ruin skin condition.

This line of inquiry leads to a fun conspiracy/woo hypothesis; Grant Genereux[5]'s claims that what it does is trigger stem cells to differentiate in the epithelial layers of the skin, which makes thicker skin in the short term (wrinkle free) and worn out stem cells and thick skin in the longer term - and that many small vessels in the body have an epithelial lining of 'internal skin' and that thickens by the same mechanism leading to narrowing and closing of all kinds of internal vessels - tear ducts and sweat glands and blood vessels and inside the kidneys and liver and inner ear, etc. which cause the dry skin and dry eyes "side effects" (direct effects really) seen outside, and the organ damage/dizziness/etc. seen inside. And that it's a teratogen by getting inside cells, damaging them, damaging the DNA/protein building mechanisms causing wider systemic damage which can be long term and is not cleared up by stopping taking Accutane, this is misunderstood as retinoids "mediating hundreds of gene expressions" but is really shotgun chaotic damage and that's why there isn't a single symptom to look for and how it gets diagnosed as many different organ-specific diseases instead of retinoid toxicity damage. And/or causing cellular apoptosis with immune system response to a percieved 'attack', which is then seen as organ damage with immune system activity present, and misdiagnosed as "autoimmune" where the immune system has decided to attack an organ for no reason, which is why autoimmune disorders never have treatments or cures and why they cluster (people with one often get more) despite no good reason that should happen.

And that this whole collection of behaviours is triggered by food with Vitamin A (retinol in the tretinoin family) in it such as dairy and meat fat and Cod Liver oil, and foods with Beta Carotene (retinoids in the same family) such as orange/yellow/dark green coloured fruits and vegetables, and fortified Vitamin A in low-fat dairy and flours and other products through the USA/Europe. And it doesn't take much more than the RDA of Vitamin A to become problematic, and once it builds up in the body beyond the level the body can handle over a few decades, it's like blue touch paper waiting to be lit. Which, he suggests, is why auto-immune disorders cluster together (if you get one, you likely get more), why Eastern Canada Prince Edward Island near a Cod Liver Oil refinery was the highest incidence of Alzheimers in the world and that has been dropping since the refinery closed, and many more connection-between-retinoids-and-disease-states including claims by other people[6].

(I called it a 'fun' idea - it is at least fun along the lines of Tyler Vigen's spurious correlation noticer. https://www.tylervigen.com/spurious-correlations even if the main idea is not true).
