Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

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. 03Glycerin (or glycerol) is a compound naturally found in your skin. It's a powerhouse humectant that pulls water into the stratum corneum.
  4. 04Topically, glycerin does several things at once:
  5. 05Your 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.
  6. 06Aquaporin-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.
  7. 07This 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.
  8. 08Just know very high concentrations (>40%) can feel tacky in low humidity.
  9. 09Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.
  10. 10Parfum is a catch-all term for an ingredient or more that is used to give a scent to products.
  11. 11Also called "fragrance", this ingredient can be a blend of hundreds of chemicals or plant oils. This means every product with "fragrance" or "parfum" in the ingredients list is a different mixture.
  12. 12For instance, Habanolide is a proprietary trade name for a specific aroma chemical. When used as a fragrance ingredient in cosmetics, most aroma chemicals fall under the broad labeling category of “FRAGRANCE” or “PARFUM” according to EU and US regul…
  13. 13The term 'parfum' or 'fragrance' is not regulated in many countries. In many cases, it is up to the brand to define this term.
  14. 14For instance, many brands choose to label themselves as "fragrance-free" because they are not using synthetic fragrances. However, their products may still contain ingredients such as essential oils that are considered a fragrance by INCI standards.
  15. 15One example is Calendula flower extract. Calendula is an essential oil that still imparts a scent or 'fragrance'.
  16. 16Depending on the blend, the ingredients in the mixture can cause allergies and sensitivities on the skin. Some ingredients that are known EU allergens include linalool and citronellol.
  17. 17Parfum can also be used to mask or cover an unpleasant scent.
  18. 18The bottom line is: not all fragrances/parfum/ingredients are created equally. If you are worried about fragrances, we recommend taking a closer look at an ingredient. And of course, we always recommend speaking with a professional.
  19. 19Phenoxyethanol is one of the most widely used preservatives in skincare (and for good reason!).
  20. 20It 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.

01How to Apply Face Serums

Skincare rules can get confusing, but when it comes to application the general rule of thumb is to pay attention to the product’s consistency. “Apply the lightest, thinnest product first and the heaviest, and more dense products last, since thinner products can’t penetrate thicker products,”says Dr. Lewis. After cleansing the face and following up with a toner, let the skin dry before using a serum. You can layer different serums on top of each other or opt for a product that has a precise mix of multiple hero ingredients, such as hyaluronic acid and vitamin C.

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.
