All about Sidr in Beauty and Skincare

What are the benefits of beauty formulas containing Sidr?

Benefit #1: Sidr is an effective natural cleanser and purifier

One of the traditional uses of Sidr is as a cleanser or wash, as well as for disinfecting wounds and promoting healing activity in damaged skin. It works well in this capacity, given that it is inherently antibacterial, and able to gently combat harmful bacteria, and other impurities, on the skin’s surface.

Benefit #2: Sidr is soothing and calming for the skin

According to studies, Sidr has proven to be very effective for addressing irritated or inflamed skin, including conditions such as redness, rashes, dermatitis, psoriasis, sensitive skin, eczema, and reactivity caused by certain illnesses or injuries. Its anti-inflammatory effects have been widely documented, and have numerous applications for both medicinal and cosmetic use.

Benefit #3: Sidr has acne fighting properties

As a result of being naturally astringent, anti-inflammatory, and antibacterial, Sidr also has the potential to greatly improve mild to moderate acne. Research has shown that in double-blind trials, patients treated with a topical solution containing Sidr experienced significant results in the reduction of acne lesions and other breakout activity as compared to products containing a placebo ingredient.

Benefit #4: Sidr is rich in nutrients skin loves

For nourishing and nurturing a glowing complexion, Sidr is also chock full of vitamins, minerals, antioxidants, and other vital nutrition for the skin. The leaves of the plant have been found to contain important components such as peptides, cyclopeptide alkaloids, flavonoids, tannins, betulinic acid, and triterpenoid saponin glycosides, which encourage healthy skin tissue and hair.

Benefit #5: Sidr helps promote skin rejuvenation and repair

Lastly, for combatting the external factors that contribute to aging in the skin, Sidr may be especially helpful as modern research has indicated that it is an effective bioactive. Bioactives are ingredients that protect the skin against UV and other harmful environmental aggressors. Therefore, by incorporating it in skincare, Sidr could potentially prevent concerns such as sun damage, dryness, dehydration, and depleted skin.

Benefit #6: Sidr nourishes the hair and scalp

Amongst the natural nutrients found in Sidr, many are known to act as hair and scalp nourishers. Ceanothic acid and Betulinic acids are terpenoids which have been proven to show anti-inflammatory properties. While most of the flavonoids and tannins work as hair growth promoters, saponin glycosides are known to work as gentle cleansers.
