Science Behind Our Formulation
Licorice Root Extract
All Koolit products are enriched with botanical active ingredient, Glycyrrhiza Glabra, Licorice Root Extract which is used for treating skin eruptions, dryness, itchiness, eczema as it is scientifically proven to be high in anti-inflammaroty, antioxidant, antiseptic and antimocrobial properties. 
The benefits of Licorice Root Extract include:
- Skin lightening and skin tightening activity
- Anti-inflammatory activity to reduce swelling and itchy skin
- Antioxidant activity to neutralise free radical damage and skin oxidative stress (anti-aging)
- Anti-acne by controlling acne-inducing bacteria 
Koolit contains two licorice compound known as glycyrrhizin, a potent antioxidant, and glabridin which effectively soothes sensitive skin irritation while brightening skin marks left from frequent skin scratching.
Functionally, the following are some of the many benefits of licorice root extract which can be found in Koolit Dermacare:
- Reduce Dryness & Itchiness
- Acne Control
Enriched with skin calming and skin soothing natural ingredients, Koolit’s formulation had to ensure the skin was also able to absorb the goodness of the ingredients. Our R&D team had to research and create a spreadable and easily absorbing formula which went deep into the skin to reduce itching, swelling and redness from within the dermis layer, unlike other creams which only moisturises the surface of the skin. By soothing the skin from within, the inflamed epidermis layer is calmed. This mechanic treats the skin for the long term while forming a layer of protection on the epidermis layer to keep irritants and microbes away. Koolit also provides the excellent long lasting moisturisation for optimal skin health.
Skin Brightening Mechanism
Koolit also possesses skin brightening property, Glabridin. Basically, tyrosinase is an enzyme in your skin that synthesizing melanin (dark spots). Glabridin goes in and stops tyrosinase from working and stops the production of dark spots or pigmentation. This means lightening those dark spots gently while brightening your skin.
With the rapid absorption and meticulous formulation, we (and our many users) found Koolit to powerfully soothe skin sensitivity while maintaining it’s safe, natural and gentle care on all skin types, including baby skin.
40x Higher Antioxidants
Koolit Range is high and potent in antioxidants which neutralises the effects of free radicals in our body. An inbalance of free radicals when our body does not have sufficient antioxidants can lead to skin oxidative stress and pre-mature skin aging which is seen as dryness, wrinkles and damaged skin barrier. This is why the content of having 40x Higher Antioxidants in Koolit is so important in our products, in order to gentle care and protect our skin from within.
>20% TEWL Reduction
Transepidermal water loss (TEWL) is the amount of water loss or passively evaporated from the skin to the external environment due to impaired skin barrier function. It can indicate the integrity of the skin barrier function which inherently refers to the skin's ability to retain moisture and has been shown to be correlated to skin aging.
Upon study and testing the volar surface of the forearm under standardized conditions, Koolit Calming Cream was found to significantly slow down moisture loss from the skin. Koolit induced a longlasting moisturizing effect up to 24 hours, with a 24.6% reduction in TEWL.
Some other ingredients found in Koolit include :
- Natural Vitamin E
Clinically proven to ease itchy and irritated skin, Koolit contains Vitamin E in a natural form that is potent and readily absorb by the skin, unlike cheaper market brands which use synthetic forms of Vitamin E. Topical vitamin E can diminish the UV-induced skin damage and swelling, thickness and erythema.
- Jojoba Seed Oil – Simmondsia chinensis seed oil
Found in Koolit Soothing Lotion, Jojoba seed oil is the only plant producing significant quantities of liquid wax esters similar to the lipids produced by human skin. This helps foster absorption while the wax esters soothe and naturally promote skin restoration.
- Olive Fruit Oil – Olea europaea
Found in Koolit Calming Cream and Koolit Cooling Body Moisturiser, Olive oil being naturally rich in Vitamin E, Vitamin K, anti-inflammation and antioxidant properties help calm irritated skin and provide smooth softness to dry cracked skin.
Apart from licorice root extract, our Itch Relief Cooling Range contains:

Ceramides are essential components of skin barrier which help to restore and reinforce skin’s protective barrier structure by filling gaps in the lipid bilayer with skin-identical ceramide. Koolit does not use low grade forms of ceramides but contains 5x skin mimic ceramides in 3:1:1 ratio for optimal skin repair. Rebuilding of skin barrier with Koolit will help maintain skin health and moisture in the long term.
