Emollient, Humectant, Skin Conditioning

Aloe Barbadensis Leaf Extract is an extract of the leaves of the aloe, Aloe barbadensis, Liliaceae.

You may know Aloe to be a good sunburn reliever and inflammation reducer. This is because it contains many components that are known to help reduce irritation and itchiness. These include vitamins, amino acids, polysaccharides, and more. The high water content of aloe also helps give a cooling effect.

Aloe contains the antioxidants Vitamins A, C, and E. These vitamins neutralize free radicals. Free-radicals are molecules that may damage your skin cells, such as pollution.

The aloe plant is naturally abundant in polysaccharides, a carbohydrate made of sugar molecules. Polysaccharides help hydrate your skin by mimicking your skin's natural carbohydrates.

As it is easily absorbed by the skin, aloe is a great moisturizer. It is both a humectant and emollient. Emollients help trap moisture in your skin, keeping your skin soft. Humectants draw water from the air to your skin.

Other components of aloe include sugars such as monosaccharides and polysaccharides, folic acid, choline, many common minerals such as calcium, fatty acids, amino acids, and Vitamin B12.

Aloe does not protect against UV rays, despite it soothing sunburns.

There are over 420 species of aloe but Aloe Barbadensis is the most commonly used for topical products.

Smoothing

Niacinamide has emerged as an all-star ingredient due to its many benefits.

It is known to treat acne by reducing inflammation. It also helps fade dark-spots and strengthen the skin by promoting the growth of the ceramide barrier.

Other benefits include smoothing wrinkles and minimizing redness.

The cherry on top? Niacinamide can also help build keratin, a protein that keeps skin firm.

When incorporating niacinamide into your routine, look out for concentration amounts. Typically, 5% niacinamide provides benefits such as fading dark spots. However, if you have sensitive skin, it is better to begin with a smaller concentration.

Niacinamide can be mixed with other ingredients to boost benefits. For instance, it has shown to be effective when used with copper, folic acid, and zinc to treat acne.

I actually love this exfoliating serum for my very oily skin! I use it 3 times a week and only use two baby drops of it that I apply mostly on my T zone. The mornings after I use it, my skin feels lighter and purified. Try not to mix this serum with retinoids or vitamin C, although I mixed it with only derivatives (was told it’d be ok by employees), my skin felt a bit sensitive when I did.

Could be better but still loved it
Sticky and goopy but non-irritating. Was a little hard and messy to use with the dropper. Would probably be better in a pump.

I found this to be pretty ineffective for my blemishes. The bottle is also pretty small. Could be used when one's first starting chemical exfoliation or if your skin is very very sensitive.
