Ingredients Explained

  1. 01These ingredients are found in both products.
  2. 02Ingredients higher up in an ingredient list are typically present in a larger amount.
  3. 03Alpha-Glucan Oligosaccharide is a prebiotic. It prevents harmful bacteria from growing on skin by keeping the skin's microbiome in balance.
  4. 04Another benefit of this ingredient is its antioxidant properties. Antioxidants protect our skin from oxidative damage.
  5. 05Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:
  6. 06Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.
  7. 07Though 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.
  8. 08Caprylyl Glycol is a humectant, skin conditioner, emollient, and preservative booster derived from either caprylic acid or synthetically created.
  9. 09Typical use levels vary from 0.3-1% as a preservative booster and go up to 2% to condition skin.
  10. 10Because it is not a free-fatty acid, this ingredient is fungal acne safe (there's nothing for Malassezia to feed on).
  11. 11Citric Acid is an alpha hydroxy acid (AHA) naturally found in citrus fruits like oranges, lemons, and limes.
  12. 12Like 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.
  13. 13However, this exfoliating effect only happens at high concentrations (20%) which can be hard to find in cosmetic products.
  14. 14Due to this, citric acid is usually included in small amounts as a pH adjuster. This helps keep products slightly more acidic and compatible with skin's natural pH.
  15. 15In skincare formulas, citric acid can:
  16. 16While it can provide some skin benefits, research shows lactic acid and glycolic acid are generally more effective and less irritating exfoliants.
  17. 17Most citric acid used in skincare today is made by fermenting sugars (usually from molasses). This synthetic version is identical to the natural citrus form but easier to stabilize and use in formulations.
  18. 18Rosacea skin has a lower threshold for acids generally, with 62.5% of rosacea subjects in one study reacting to lactic acid in a sting test. This is why we mark citric acid as a potential rosacea trigger.
  19. 19However, this ingredient shows up as a pH adjuster or chelator at roughly 0.1-1% in many products. These low levels are unlikely to be an issue for rosacea skin and becomes a potential trigger at exfoliating concentrations (20%). Because everybody's…
  20. 20Glycerin (or glycerol) is a compound naturally found in your skin. It's a powerhouse humectant that pulls water into the stratum corneum.
