What is sebum, and why does it matter?​ The skin is made up of sebaceous glands that secrete sebum. In some people this stays within a normal range, in others it doesn't. Excess sebum production, like what's seen in seborrheic dermatitis, can create a favorable environment for fungal growth. Sebum is a natural, oily substance produced by the sebaceous glands in our skin. Chemically, it's a complex mixture of triglycerides, fatty acids, waxes, squalene, and cellular debris. Even though it's often treated as the enemy of good skin, sebum is actually the skin's first line of defense — it protects against dehydration, external factors, and microorganisms. The amount produced varies from person to person and depends on genetic predisposition (nothing we can do about that), hormones, diet, and external factors. The skin is made up of three layers: the epidermis, the dermis (where the sebaceous glands are located), and the hypodermis. Sebum is even healthy for the skin — it helps with hydration, defends the skin, and rebuilds the skin barrier, among other things. Overproduction, though, can lead to an unfavorable environment, clogged pores, and breakouts. It's typically secreted most heavily in the T-zone — nose, forehead, and cheeks. Topical treatments for oily skin​ Retinoids are a family of compounds derived from vitamin A, including natural forms like retinol, retinaldehyde, retinoic acid, and retinyl esters, as well as synthetic forms like adapalene and tazarotene. Mechanism of action: Retinoids work by binding to nuclear receptors in skin cells. Human skin contains three types of RAR (retinoic acid receptor) — RAR-α, RAR-β, and RAR-γ. To become functional, an RAR receptor has to pair with an RXR receptor (retinoid X receptor), forming what's called a heterodimer. In the epidermis, RAR-γ makes up about 90% of all RAR receptors, and RXR-α makes up about 90% of all RXR receptors. Because of this, human skin is mostly regulated by the RAR-γ/RXR-α heterodimer combination.

What’s even more bizarre is that injection-related pain is massively reported, more consistently so than its supposed benefits². Quickly, Glycyl-L-histidyl-L-lysine (GHK) is a tripeptide isolated from human plasma³, which possesses a high affinity for copper (II) ions, with which it spontaneously forms a complex (GHK-Cu). GHK alone has been shown to be responsible for the collagen boost⁴ and no injection-related pain has been reported with it⁵, so go for it if you want but it's the added copper that is responsible for this myriad of blessings; EXAMPLES : The complex, unlike GHK alone, helps activate matrix metalloproteinases, which break down damaged tissue so it can be replaced with healthy tissue⁶. OR Compositions of copper (II) containing compounds have been show to accelerate the healing of wounds in warm-blooded animals, and more specifically the systemic loading of copper (II) compounds to accelerate the rate of wound healing following injury or surgery to warm-blooded animals.⁷ ; ...and consequently what seems to cause tissue damage during injection. If we look at the cayman chemicals reviews of the molecules in question : The main differences are the addition of a copper atom and a significantly worse solubility profile, which suggests a causal relationship between these two differences (meaning that the added copper induces the worse solubility). In fact, we know that metals are gay Simply, they like to move a lot, they're playful building blocks that like to change and mix , while other atoms are stronger and stick together better, other atoms, like those in water or air, are like super strong blocks that hold together really well. They don’t like to change as much, so they are usually more stable. Seriously, metals require ions to stabilize in various contexts, primarily due to their tendency to lose electrons and form positive charges, the ions in PBS can neutralize the positive charge of the copper ions, reducing the likelihood of oxidation or other reactions that would destabilize the copper. PBS also maintains a stable pH, which is important for keeping copper in its soluble form. In bac water or regular saline, changes in pH can lead to precipitation or oxidation of copper ions.

Hey, I started college about a month ago. And I have noticed I sometimes have hard time remembering math problems, as well as with focus. What are the best peptides that can help with memory, focus, and cognitive development? And what are the risk that can come with it (If there are any)?

Not sure about yall, but Alzheimer's is in the wood pile for me. With that in mind I am very curious about brain health and performance. I am curious what you do to help your brain/cognition/memory. I am currently taking creatine (10g ED) for the brain and muscle benefits. I have tried P21 and Dihexa. The jury is still out on Dihexa. I think I will give it another swing once I get through the month of May(its a busy month). P21 seemed to help, but now it seems scarce so doing follow research is not happening. I suspect some of you have way more knowledge, about brain performance, than me since my idea of prepping my mind for study was to pound coffee.
