Ingredients higher up in an ingredient list are typically present in a larger amount. Adenosine is a purine nucleoside that your body already makes in every cell. In skincare, it acts mainly as a skin conditioning and anti-aging agent. The way it works is fairly well mapped out: Your skin has cells called fibroblasts that build collagen (the stuff that keeps skin firm and smooth). Adenosine basically flips a switch on these cells that tells them to get to work making more collagen and other proteins. These cells slow down on their own as skin ages, so Adenosine helps give them a little nudge to keep going. The clinical backing is pretty solid too. A blind, randomized, placebo-controlled trial of 126 women aged 45-65 tested a 0.1% cream twice daily and found real improvements in crow's feet and frown lines using a precise 3D skin-mapping technique; these changes showed up by week 3 and held at 2 months. A later study using Adenosine-loaded dissolving microneedle patches reported gains in wrinkle depth, dermal density, elasticity, and hydration. On concentrations, South Korea's Ministry of Food and Drug Safety has set 0.04% as the approved functional anti-wrinkle level. You'll typically see this ingredient used somewhere in the 0.04-0.1% range since it works at low doses. This ingredient has been found safe for cosmetics with the data showing no irritation or sensitization. Overall, this is a great ingredient for any anti-aging routine and has no photosensitizing effect, so it suits both AM and PM use. Biotin is a B vitamin that is naturally produced by our bodies. It is also called Vitamin H. Our bodies use biotin in the metabolism process. It also helps our bodies use enzymes and move nutrients around. A biotin deficiency can lead to brittle hair and nails. More research is needed on applying biotin topically. However, taking biotin orally has been shown to help nourish the skin, hair, and nails. They play a role in forming skin-hydrating fatty acids. Biotin is water-soluble. It can be found in foods such as fish, eggs, dairy, nuts, and meat. Vitamin H stands for "haar" and "haut". These are the German words for hair and skin. Chlorhexidine Digluconate is a preservative. It can worsen eczema. We don't have a description for Chrysin yet. Ci 77891 is a white pigment from Titanium dioxide. It is naturally found in minerals such as rutile and ilmenite. It's main function is to add a white color to cosmetics. It can also be mixed with other colors to create different shades. Ci 77891 is commonly found in sunscreens due to its ability to block UV rays. Citric Acid is an alpha hydroxy acid (AHA) naturally found in citrus fruits like oranges, lemons, and limes. Like other AHAs, citric acid can exfoliate skin by breaking down the bonds that hold dead skin cells together. This helps reveal smoother and brighter skin underneath. However, this exfoliating effect only happens at high concentrations (20%) which can
