How Is Carob Extract Used in Cosmetics?

The carob extract is a plant ingredient known for its moisturizing benefits that can be found in skin care and also in hair care products. From the pulp of carob trees, it is also possible to extract a molecule with self-tanning and antioxidant properties called inositol.

Carob Extract in Cosmetics: How to Use It.

Listed under the INCI name of “Ceratonia Siliqua Seed Extract”, the extract of carob is a form of common use, encountered in skin and hair care. It is an oily extract containing the main active constituents of the plant, namely sugars, proteins, polyphenols, vitamins, and minerals. This active ingredient is obtained by macerating the carob pulp in a hydroalcoholic solution (based on alcohol and water). The mixture is then filtered and purified to obtain a clear extract.

This diversity of components makes carob extract a moisturizing active ingredient via a humectant mechanism: it captures water molecules and retains them in the surface layers of the skin. It also improves the structural integrity of hair fibers, strengthening the barrier function of the cuticles and protecting the hair from various external aggressions.

In skin care, the extract of carob seeds is found in certain creams, serums and hydrating masks. This compound is not photosensitizing and can be used in the morning. Be careful, however, that the other compounds in the formulas are not either. Moreover, the benefits of extract of carob seeds are adapted to all the types of skin.


In hair care, the oily carob extract is present in some shampoos, conditioners, and masks. This compound has no contraindications and is used according to the instructions of the product concerned. Carob is suitable and beneficial for all hair types, but is particularly recommended for dry, devitalized hair as well as hair prone to frizz.

Inositol: How Is It Used?

From the carob tree fruit, it is also possible to extract inositol, which has a similar name according to the INCI system. This molecule protects the skin from photoaging by activating the synthesis of collagen I in the fibroblasts. It is therefore often found in certain skin care products for mature skin and to prevent the appearance of the signs of aging.

Inositol also acts as a humectant and maintains the water content of the skin, hence its presence in certain moisturizers such as serums, creams, gels, or masks.

In addition, this compound intensifies and prolongs the skin's tan thanks to an innovative mechanism based on the activation of second messengers involved in melanin synthesis. It is therefore also used in certain self-tanning products. These are applied evenly with short circular movements directly with the fingers. Do not forget to wash your hands afterward.

Be careful! Self-tanning serum does not protect against the sun's UV rays and cannot replace a sun cream! Be sure to protect yourself from UV rays with a broad spectrum sunscreen before exposure.
