Ingredients Explained

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.

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.

Propanediol is an all-star ingredient. It softens, hydrates, and smooths the skin.

It’s often used to:

Propanediol is not likely to cause sensitivity and considered safe to use. It is derived from corn or petroleum with a clear color and no scent.

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!

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. 031,2-Hexanediol is a synthetic liquid and another multi-functional powerhouse.
  4. 04It is a:
  5. 05Humectant, drawing moisture into the skin
  6. 06Emollient, helping to soften skin
  7. 07Solvent, dispersing and stabilizing formulas
  8. 08Preservative booster, enhancing the antimicrobial activity of other preservatives
  9. 09Beta-Glucan is a soluble polysaccharide (a chain of glucose sugars) sourced from the cells walls of oats, baker's yeast, mushrooms, and seaweed.
  10. 10It's a rare ingredient that pulls double-duty as a heavy-duty hydrator and skin-soothing repair agent.
  11. 11On the surface, it acts as a humectant that holds water in place and reduces moisture loss for a plumper, smoother feel, while its anti-inflammatory and antioxidant properties make it a great pick for calming redness or sensitive skin
  12. 12The more interesting story is underneath:
  13. 13Despite its large molecular size, oat beta-glucan has been shown to penetrate the epidermis and reach the dermis by slipping between skin cells. Here, it interacts with fibroblasts and macrophages to nudge collagen synthesis and support wound repair.
  14. 14A small 2005 split-face clinical study of 27 subjects found topical beta-glucan produced measurable reductions in wrinkle depth, height, and roughness after 8 weeks of use.
  15. 15It is worth noting the trial was small and the penetration testing used frozen, irradiated skin so the anti-aging data is encouraging rather than definitive.
  16. 16This ingredient gets along with pretty much everything and is typically used around 0.1-1%.
  17. 17Fungal acne: This ingredient is not a food source for the Malassezia yeast because it is a glucose polysaccharide with no fatty acid or ester component.
  18. 18Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:
  19. 19Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.
  20. 20Though 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.

01Is Serum Good for All Skin Types?

Serums are a form of skincare that can be added to any routine no matter what your skin type is. All skin types can benefit from the use of a serum since there are so many different formulations that can target specific skincare concerns. “Serums are used for hydration,to aid [or] maintain the skin barrier, or treat skin issues like acne or rosacea,” says Dr. Lewis. The type of serum that you may use should depend on the skin issue you’re trying to target. Think of serums as a treatment for the skin. “Some serums can reverse damage and help prevent free radicals that cause the signs of aging skin,” adds Dr. Lewis.

02When and How to Use Hyaluronic Acid in Your Routine

Products with hyaluronic acid can be used in the morning or at night (or both!). Applying the hydrating ingredient at night will restore your skin’s resilience while you sleep, and applying it in the morning will leave your skin feeling plump, hydrated and ready for makeup. Hyaluronic acid is great at providing topical hydration when it’s introduced into a balanced skincare routine. According to Dr. King, it’s important to pair your hyaluronic acid products with an emollient or occlusive moisturizer to lock in hydration.
