Non-comedogenic oils: effects on oily skin

Non-comedogenic oils are those that have the ability to keep the skin free of pimples or any form of acne. They are considered "non-comedogenic" because they are ranked below two in the scientific study made in 1989 by Dr. Fulton «Comedogenicity and irritation of ingredients commonly used in skin care products».

The study established a numerical rating from 0 to 5, a measure that determined how pores grew after individual cosmetic ingredients were applied to the skin. Thus, 0 has a zero probability of clogging pores, class 1 a low probability of causing it and class 2 a moderately low possibility.

From class 3 on, it begins to be considered comedogenic, since its probability of obstruction is moderate. Types 4 and 5 are high class, as they will almost certainly detonate the obstruction. So are there non-comedogenic oils? We invite you to discover it.

Effects of non-comedogenic oils on oily skin

Oily skin is one that has excess sebum in different areas, which can appear brighter. It also has large pores and an uneven skin texture. A common problem among people with this type of skin is acne.

However, infections, inflammation, and other unwanted effects associated with excess fat are also common. Is it good to use non-comedogenic oils? Let's see its main effects.

Sebum regulation

The sebaceous glands are located in the dermis. The function of sebum is to lubricate and protect the surface of the skin. Typically, adults produce 1 mg per 10 cm of skin every 3 hours. When there is hypersecretion, enlarged pores and acne can appear.

Fortunately, as an article published in Journal of Clinical and Aesthetic Dermatology, there are oils with non-comedogenic characteristics that reduce excess fat. Thus, the skin is kept clean and in optimal condition.

Acne free

Acne is a skin disorder where the hair follicles become clogged with oil and dead cells. Therefore, comedones, blackheads and pimples appear. As a result of an overproduction of sebum, it is a common problem with oily skin. However, as we have discussed, non-comedogenic oils help regulate it.

Hydration

Good hydration helps keep water levels balanced. Thus, these oils strengthen the protective barrier of the skin. In addition, they prevent dryness and aging.

Antiseptics and antifungals

Antiseptic and antifungal oils are capable of destroying microorganisms or reducing their growth. The main skin infections are cellulitis and staph infections. Those caused by fungi cause athlete's foot and yeast infections.

In this sense, these types of products become adjuvants against microorganisms that affect the skin. Its regular application cleans the pores and reduces the presence of pathogens on their surface.
