Vitro Testing

In vitro testing is an excellent and cost-effective testing method that is a versatile option for animal testing. “In vitro” is the Latin translation of “in glass,” which implies a test that is performed outside of a living organism.

In vitro testing existed several years ago, and several improvements in this type of testing have profited the cosmetics industries, particularly when it comes to examining the sensitivity of cosmetics ingredients.

Let’s take a close look at how in vitro testing has improved the quality and safety of cosmetics.


Transforming The Cosmetics Industry Across the Globe

The cosmetics industry has been remarkably transformed by in vitro testing across the globe. One of the critical factors that have brought about an increase in the popularity of this kind of testing is a total ban on animal testing.

There has been significant development of in vitro testing because of this ban, resulting in it becoming cost-efficient and far more effective than it uses to be.

Scientists are going on with confirming the safety of this type of testing method and its benefits over animal testing. In doing so, people are positively acknowledging this and rapidly withdrawing from animal testing processes.

As developments progress, in vitro testing is believed to become more beneficial, and, hopefully, it will shortly be considered as a lasting alternative for animal testing.


Benefits of In Vitro Cosmetics Testing.

In vitro testing can easily be used to taste the efficacy and safety of cosmetic ingredients. The testing can detect toxic properties in cosmetic products as well as confirming the ingredients claimed to be used.

Several cosmetic dealers use this method to confirm the efficacy of a product and to see if it meets the regulatory standards. Also, cosmetic manufacturers are expected to abide by these standards and policies to remain in regulatory compliance. In vitro testing, it’s possible to examine an ingredient’s likelihood of causing adverse skin reactions, dermal corrosion as well as allergic contact dermatitis(AC).

This non-animal testing method has proven very beneficial in examining how cosmetics works with the body from several perspectives, including epidermal inflammation and protein binding.

One of the newest in vitro type of testing that is enhancing the quality and safety of cosmetics is the 3D reconstruction of tissues. Results obtained from this type of testing can be incorporated with bioavailability data along with skin metabolism data to provide easy identification of skin allergens. Additionally, it can help specify the characterization that gets on with the relative potency of ingredients.

The various in vitro testing methods that can be used in testing ingredients are according to different sets of criteria. For example, some elements are tested for oily skin, skin firmness, regulatory safety, and toxicity efficacy, product claims, as well as confirmation of the presence of the listed ingredients. Such tests include:


Safety and Toxicity Testing

  • Cytotoxicity, which provides for skin/eye irritation and corrosion
  • Phototoxicity (which is skin irritation that is chemically induced)
  • Mutagenicity (damage to DNA)

Efficacy Testing

  • Anti-aging properties
  • Oily skin management
  • Hydration
  • Skin pigmentation
  • Anti-hair loss properties

Skin Hydration and Skin Barrier

  • Full-thickness skin models
  • Skin explant models
  • Reconstructed human epidermis models

Skin Firmness

  • Dermal equivalent models
  • Full-thickness reconstructed skin models
  • Normal human dermal fibroblasts models

Oily Skin

  • Sebocyte cell line models
  • 3D sebocyte cell line models
  • Sebocyte cell line in response to androgens models
