Asterwood Naturals Argireline Serum Versus Asterwood Naturals Triple Repair Anti-Aging Complex Serum

Asterwood Naturals Argireline Serum Versus Asterwood Naturals Triple Repair Anti-Aging Complex Serum Detailed comparison of Asterwood Naturals Argireline Serum versus Asterwood Naturals Triple Repair Anti-Aging Complex Serum. This anti-aging serum is formulated around Acetyl Hexapeptide-8 and Hyaluronic Acid to soften the look of wrinkles. This anti-aging serum is formulated around Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7 to soften the look of wrinkles and refine skin texture.

Ingredients higher up in an ingredient list are typically present in a larger amount. Acetyl Hexapeptide-8 (also known as Argireline) is a synthetic hexapeptide that is often called a "topical Botox alternative". It works by mimicking how Botox relaxes muscles; it interferes with the signaling process that tells your facial muscles to contract. This can help soften expression lines like forehead wrinkles or crow's feet over time. The comparison to Botox does have limits because the molecule is water-loving and relatively large. Acetyl Hexapeptide-8 has a hard time absorbing deeply enough through the skin's outer barrier to actually reach the muscles. So whether it truly works the way Botox does at a biological level is still up for debate, but early clinical outcomes are fairly encouraging. A 12 week human study of a multi-ingredient regimen containing this ingredient saw: While some studies have observed improvements in wrinkle appearance, it is important to note that more consistent results are seen in multi-ingredient formulations (vs just Acetyl Hexapeptide-8 alone). Some research studies also used higher concentrations (up to 10%) while this ingredient is usually found in concentrations up to 0.005% in leave-on formulations. Benzoic Acid is an organic acid that shows up in cosmetics as a preservative. It helps keep a product from spoiling by holding back the growth of yeast, mold, and some bacteria. This ingredient also functions as a fragrance ingredient that helps mask the unpleasant scent of other ingredients. The way it works is worth understanding; benzoic acid works when the formula is acidic. It is able to sneak into a microbe's cell and mess up how it functions to stop it from growing in an acidic product. However, the acid switches to an inactive form and stops working if a product isn't acidic enough (above ~5 pH). This is why you'll often see it in low pH products or teamed up with other preservatives to cover the gap. Safety wise, it's one of the better studied preservatives out there. The Cosmetic Ingredient Review Expert Panel has concluded this ingredient to be safe for use in cosmetic formulations at concentrations up to 5%. A large international review found this ingredient had no effects on the human body and had low irritation potential. Just so you know, real world use is usually much lower than the 5% ceiling (usually 1% of less). The EU caps it at 2.5% in rinse-off products, 1.7% in oral care, and 0.5% in leave-on products. One thing worth mentioning (it's nothing to worry about): some people get a little stinging or flushing where they apply it. This isn't a true allergy; it's a temporary and harmless reaction. This is the same kind of mild tingle you might notice from sorbic acid. Dehydroacetic Acid is a synthetic preservative that keeps your products safe from microbes. As an organic acid, it penetrates microbial cell walls and disrupts cellular metabolism. This makes it
