The Real Benefits of Aloe for Hair, According to Experts
3. Fading Dark Spots and Stretch Marks
There are two compounds in aloe that may fade dark spots and stretch marks: aloesin and aloin. In one study, aloesin was applied four times per day for 15 days and was found to be effective in treating UV-induced and post-acne hyperpigmentation.
Another study found aloin destroyed melanin cells (an overproduction of which causes dark spots to form) in pigmented cells by blocking activity of tyrosinase, an enzyme responsible for melanin production.
4. Managing Acne
Aloe vera contains naturally occurring salicylic acid, urea nitrogen, cinnamic acid, phenols and sulfur—all of which inhibit the growth of fungi, bacteria and viruses. It also has anti-inflammatory capabilities, which suppresses P. acnes, the bacteria that causes acne. Salicylic acid is currently one of the best ways to prevent acne, since it sheds dead cells from the outer layer of the skin and decreases redness and inflammation.
5. Soothing Skin Conditions
Flare-ups of psoriasis—an inflammatory condition that causes red, itchy and scaly patches—may be better managed with aloe vera in the mix, thanks to its anti-inflammatory properties. Ditto eczema, a skin condition that causes your skin to become red and itchy and more prone to fungal and bacterial infections: Aloe has antiseptic, antibacterial, anti-fungal and anti-inflammatory properties that may soothe eczema by hydrating and protecting it from contaminants.
6. Slowing Signs of Aging
Because aloe vera contains vitamins C and E, it stands to reason it may help prevent the formation of free radicals, which are the molecules that cause cell damage. Meanwhile, the salicylic acid it contains acts as a gentle exfoliant—and once those pesky dead skin cells are out of the way, your other skin-care products might better penetrate the surface and do their thing more effectively as a result.
