Aloe Vera for Skin: Know the Reason behind its magic scientifically
Aloe vera (Aloe barbadensis) has been
revered for centuries as a natural remedy for a variety of skin conditions. Its
popularity today is supported by both traditional use and a growing body of
scientific research. The plant’s gel, found inside its thick, fleshy leaves, is
rich in water, vitamins, minerals, antioxidants, and a range of bioactive
compounds that contribute to its skin benefits (1, 2).
How Aloe Vera Works on the Skin: Step-by-Step Mechanisms
1. Hydration and Moisturization:
Mechanism: Aloe vera gel is composed mainly of water and
polysaccharides, which help retain moisture in the skin by forming a protective
barrier. These mucopolysaccharides bind moisture to the skin, keeping it
hydrated and reducing dryness and flakiness.
2.
Anti-Inflammatory Effects:
Mechanism: Aloe vera contains compounds such as phytosterols,
and glycosides, which reduce inflammation by inhibiting the production of
inflammatory mediators. This helps soothe irritated skin, reduce redness, and
calm conditions like eczema and psoriasis (3, 4).
A study published in an internationally
recognised journal, i.e., Molecular Immunology, revealed that aloe
vera has been shown to decrease the levels of inflammatory cytokines such as
tumor necrosis factor-alpha (TNF-α) and interleukin-1 beta (IL-1β) in wound
tissues. This reduction in inflammatory mediators helps to calm the skin and
reduce swelling, redness, and pain. It also inhibits the production of other
pro-inflammatory cytokines like IL-6 and IL-8, while increasing anti-inflammatory
cytokines such as IL-10 (3, 4, 5).
3.
Antioxidant Protection:
Mechanism: Aloe vera is rich in antioxidants, including vitamins
A, C, and E, as well as flavones and anthraquinones. These antioxidants
neutralize free radicals generated by UV exposure and pollution, preventing
oxidative damage to skin cells (3, 4).
4.
Stimulation of Collagen and Elastin Production:
Mechanism: Aloe vera stimulates fibroblasts, the cells
responsible for producing collagen and elastin fibers in the skin. This leads
to improved skin elasticity, reduced wrinkles, and a more youthful appearance
(3).
5.
Wound Healing and Skin Repair:
Mechanism: Aloe vera accelerates the healing of minor wounds,
burns, and abrasions by promoting cell regeneration and supporting collagen
synthesis. Its anti-inflammatory and antimicrobial properties further protect
damaged skin from infection (3).
6.
Antimicrobial and Acne-Fighting Properties:
Mechanism: Aloe vera contains six antiseptic agents (lupeol,
salicylic acid, urea nitrogen, cinnamic acid, phenols, and sulfur) that
inhibit the growth of bacteria, fungi, and viruses. This helps prevent and treat
acne by reducing the presence of acne-causing bacteria and soothing inflamed
skin (3).
Clinical and Experimental Evidence
According the a study published in the Iranian Journal of Medicinal Science,
and other research and reviews confirm that aloe vera has excellent anti-inflammatory
effects in the context of wound healing, burns, and chronic skin conditions.
For example, aloe vera dressings have been shown to reduce recovery time,
minimize redness and itching, and prevent wound infections compared to standard
treatments.
Experimental models have demonstrated
decreased pain, shorter healing time, improved wound contracture, and increased
tensile strength in wounds treated with aloe vera, all of which are linked to
its anti-inflammatory and proliferative actions.
How to Use Aloe Vera in Daily Life for Maximum Benefits
1.
Direct Application of Fresh Aloe Vera Gel
Cut a fresh aloe vera leaf, scoop out
the clear gel, and apply it directly to clean skin.
Leave it on for 10–20 minutes, then
rinse with lukewarm water.
Use daily or as needed for hydration,
soothing sunburn, or treating minor irritations.
2.
As a Moisturizer or Serum
Use pure aloe vera gel or products with
a high concentration of aloe as a daily moisturizer.
Apply after cleansing and before
sunscreen in the morning, or as a soothing night treatment.
2.
Dietary Supplementation
Some studies suggest that oral aloe vera
supplementation can improve skin elasticity and reduce wrinkles, but consult a
healthcare provider before ingesting aloe products, as not all forms are safe
for internal use.
