Dime Beauty Hyaluronic Acid Serum Versus Goldfaden MD Needle-less Line Smoothing Concentrate Detailed comparison of Dime Beauty Hyaluronic Acid Serum versus Goldfaden MD Needle-less Line Smoothing Concentrate. This hydrating serum is formulated around Hyaluronic Acid to hydrate skin and soften the look of wrinkles. This anti-aging serum is formulated around Laminaria Digitata Extract and Hyaluronic Acid to soften the look of wrinkles and hydrate skin. Water Hyaluronic Acid Phenoxyethanol Ethylhexylglycerin Water, Hyaluronic Acid, Phenoxyethanol, Ethylhexylglycerin Laminaria Digitata Extract Acetyl Hexapeptide-8 Melaleuca Alternifolia Leaf Extract Laminaria Digitata Extract, Water, Hyaluronic Acid, Acetyl Hexapeptide-8, Phenoxyethanol, Ethylhexylglycerin, Melaleuca Alternifolia Leaf Extract These ingredients are found in both products. Ingredients higher up in an ingredient list are typically present in a larger amount. Ethylhexylglycerin is created from glycerin. It is a multitasker ingredient that: The CIR Expert Panel found minimal skin absorption or sensitization of any kind in a safety assessment. Though this ingredient is considered well-tolerated, a small number of cases of allergic dermatitis have been published since 2002. Just be sure to patch test if you are unsure. Industry-reported use ranges from 8% in rinse-off products and 2% in leave-on formulations. Hyaluronic acid (HA) is a glycosaminoglycan (basically a long sugar chain) that your skin already makes on its own. In your skin, HA lives in the extracellular matrix and acts as the body's moisture reservoir. Topically, HA is a humectant that binds water and helps skin look more plump, smooth, and hydrated. The only catch is that HA isn't a single thing; it actually comes in a wide range of molecular weights (~50 - 2,000+ kDA) and size matters. Some clinical evidence links low molecular weight versions to improved wrinkle depth, elasticity, anti-inflammatory effects, and barrier repair. This is why the best HA serums blend the two sizes together so you get the best of both worlds. The majority of cosmetic HA is produced by bacterial fermentation, typically using Streptococcus or Bacillus strains. Typical use levels in skincare sit around 0.1-2%. A clinical study using a 0.2% low-molecular weight HA gel showed improvement in facial seborrheic dermatitis with excellent tolerance. These are some other common types of Hyaluronic Acid: Phenoxyethanol is one of the most widely used preservatives in skincare (and for good reason!). It has a large spectrum of antimicrobial activity and especially effective bacteria, yeast, and mold while only having a weak effect on your skin's natural microbiome. On a cellular level, it disrupts the cell membranes of microbes by poking holes that make the cell leak. This shuts down the chemical reactions the microbe needs to make energy so it can no longer survive. Another perk of this ingredient is that it stays functional across a wide pH range (3-10). You'll often see it paired with boosters like Ethylhexylglycerin; one study showed that a 1:9 ratio of Ethylhexylglycerin to Phenoxyethanol damages bacterial membranes as effectively as doubling the Phenoxyethanol concentration on its own. Typical use concentrations range from 0.3-1% depending on the formula, and this ingredient is capped at 1% int the EU. Safety-wise, the fear mongering does not hold up to the evidence. The EU's Scientific Committee on Consumer Safety and FDA consider it safe as a preservative at up to 1%, including for children of all ages. Adverse systemic effects only showed up in animal studies at exposures roughly 200x higher than what people get from cosmetics. And despite its very widespread use, this ingredient is a rare sensitizer and allergic reactions are uncommon
