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. Camellia Oleifera Leaf Extract comes from the leaves of the tea oil plant, the cousin of the green tea plant Camellia Sinensis. This ingredient is mainly added to skincare as a mild skin-conditioning and astringent ingredient. Early lab studies show it can calm inflammation and slightly inhibit the enzyme that triggers dark spots. Modern studies also show it to have antibacterial and antioxidant effects that support anti-inflammatory use. There's no dedicated safety review for this ingredient for now, but its cousin Camellia Sinensis has been reviewed and found to be without safety concerns. Like most botanical extracts, this ingredient carries a low but real chance of contact allergy or mild irritation in sensitive individuals. Chamomilla Recutita Flower Extract comes from the Chamomile flower. Chamomile is rich in antioxidants and has anti-inflammatory properties. Several compounds found in chamomile help with soothing, such as bisbolol. Antioxidant components in chamomile make it an effective ingredient to help slow the signs of aging. Antioxidants help fight free-radical molecules, or molecules that may damage your skin. Essential oils from chamomile have been found to improve wound healing due to its antimicrobial properties. Ancient Greeks and Egyptians used Chamomile to treat skin redness and dryness. Chamomile has also been used to help treat stomach issues. Glycine Soja Oil is a plant-derived oil
