Niacinamide 4%

What it does: Smoothing

Community Rating: Loved

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.

Azelaic Acid 4%

What it does: Buffering, Masking

Community Rating: Loved

Azelaic acid is a naturally occurring acid that is derived from grains. However, the lab-created form is typically used within cosmetic products as it has better shelf-stability.

It has been shown to be effective in the treatment of acne, rosacea, and other skin conditions. Azelaic acid helps reduce the growth of bacteria that cause acne and helps to reduce inflammation.

It also helps to improve the appearance of skin by reducing the production of sebum and unclogging pores.

Azelaic Acid also has antioxidant properties. Antioxidants help fight free-radicals. Free-radicals are molecules that may damage your skin cells, such as pollution.

One of the main benefits of azelaic acid is that it is gentle and well-tolerated by most people. It is also non-comedogenic, meaning that it will not clog pores.

Caprylic/Capric Triglyceride

What it does: Masking, Skin Conditioning

Community Rating: Mixed

Caprylic/Capric Triglyceride is an emollient, solvent, and texture enhancer. It is considered a skin-softener by helping the skin prevent moisture loss.

Within a product, Caprylic Triglyceride can thicken the product and make spreadability easier by dissolving clumping compounds. An added benefit of Caprylic Triglyceride is its antioxidant properties.

Caprylic Triglyceride is made by combining glycerin with coconut oil, forming a clear liquid. Caprylic Triglyceride has not been found to be toxic for human use in concentrations under 50%.

While there is an assumption Caprylic Triglyceride can clog pores due to it being derived from coconut oil, there is no research supporting this.

Community Rating: Liked

What it does:

Community Rating: Disliked
