Answer:

Adults lose about 1% of the collagen in their skin each year, which contributes to thinning and wrinkling in aging skin. This loss of collagen may be more evident at an earlier age in women, who have lower collagen density in their skin than men. Hyaluronic acid (also called hyaluronan) is another component of skin that decreases with age. Many supplements containing collagen and/or hyaluronic acid, such as, NeoCell Derma Matrix Collagen Skin Complex, Life Extension Hair, Skin and Nails Rejuvenation Formula , Lindberg Skin Rejuvenator, and Natural Factor's Hyabest® Hyaluronic Acid , are promoted to improve the skin and some contain branded collagen ingredients such as VERISOL and BioCell Collagen or Hyabest Hyaluronic Acid , which have been tested in studies. But can taking collagen and/or hyaluronic acid supplements, in the form of capsules, tablets, or powders, actually increase the collagen in skin, or improve the skin's appearance? The evidence suggests that some products may have modest effects, but the evidence for other products is weak.

INGREDIENT LIST

Ingredients Explained

  • These ingredients are found in both products.
  • Ingredients higher up in an ingredient list are typically present in a larger amount.
  • Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:
  • Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.
  • Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness.
  • Glycerin (or glycerol) is a compound naturally found in your skin. It's a powerhouse humectant that pulls water into the stratum corneum.
  • Topically, glycerin does several things at once:
  • Your skin makes glycerin on its own (mostly from sebaceous oil breakdown) and shuttles it to your outermost layer of skin, or your epidermis, via aquaporin-3.
  • Aquaporin-3 is a transporter that is essential for normal skin hydration, elasticity, and repair. Interestingly, mice lacking in AQP3 have dry and less elastic skin that can be fully corrected with glycerin.
  • This ingredient is non-irritating, plays well with almost every ingredient, and works across all skin types. Typical use is anywhere between 3-10% but can go up to 79% in some leave-on products.
  • Just know very high concentrations (>40%) can feel tacky in low humidity.
  • Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.
  • Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.
  • So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
  • You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Remember to stay hydrated!
