There are immense large amounts of health benefits your body can derive from fish oil. Read on to learn about these benefits.

Skin Whitening

Skin Whitening The omega-3s in this fish oil can boost skin immunity against certain skin conditions such as hyperpigmentation , irritation, acne, etc.¹ According to some studies, the omega-3 fatty acids in fish oil can cure and prevent hyperpigmentation and whiten the skin instead. Hyperpigmentation, a skin condition that occurs when there is excess production or distribution of melanin in the skin cells, is one of the skin disorders peculiar to white-skin people. You will see dark patches or unusual discoloration on your skin as a result of hyperpigmentation. This condition often happens due to genetics, wrong medications, aging, exposure to UV, or skin trauma. However, studies confirm that fish docosahexaenoic acid (DHA ) in omega-3 can reduce or prevent the excess melanin distribution which causes discoloration.²

Therefore, applying fish oil according to your skin care specialist or dermatologist’s prescription will help to whiten the affected area.

Reduce Acne

Acne mainly occurs due to sudden chronic inflammation of your skin cells. Skin inflammation is the breakdown of your immune system, which may allow some skin diseases as a result of stress or a poor lifestyle. When this condition happens, you may observe other symptoms like rashes, redness, itching, swelling, and further breakouts on your skin. The occurrence of acne on your skin can be painful and irritating. It spurs severe skin breakouts like cysts and pimples. However, you can prevent or reduce this skin condition with fish oil. Fish oil can help reduce the appearance of acne on your skin because it contains anti- inflammatory properties like the omega-3s. It also keeps your skin pores in constant check by reducing sebum production that may cause pores clogging.³

In addition, applying fish oil on your skin will enhance anti-bacteria that prevent acne by promoting testosterone and androgen, the hormones. Therefore, consult your healthcare provider for better directions on how to use fish oil.

Fish oil, with its omega-3s, can help boost your skin’s hydration levels by ending the symptom of psoriasis, a dry skin disease. The components of fish oil counter this skin condition by strengthening your skin’s immune system and trapping appropriate moisture into your skin cells.⁴ As a result, they help the skin maintain its hydration level and prevent any other skin conditions that might build up, like skin aging, itching, etc. Besides, fish oil is potent to treat other diseases like rheumatoid arthritis, ulcerative colitis, asthma, Parkinson’s, osteoporosis, diabetes mellitus, cardiovascular events, cancers, and depression.

The omega-3 in fish oil has the components to heal and prevent skin wound infections. Skin wounds are anything that breaks in the skin, causing the internal part to be open; examples are burns, cuts, gashes, lacerations, punctures, tears, etc. Some wounds heal naturally without applying anything, while you may need to consult your health specialist for some to heal. However, some severe wounds, like ulcers, high-level burns, and deep wounds, can trigger chronic inflammation in your skin. Therefore, you can leverage fish oil to speed up the healing process of your skin wound. Omega-3 in fish oil helps to restructure the skin tissue faster, enhancing the cellular and molecular procedures in the inflammatory phase of wound healing. 5

To prevent this skin condition, using fish oil with large amounts of omega-3 fatty acids is expedient. Omega-3 will help improve the cell membrane resilience to UV and the nutrients of the skin cells. As a result, it will help the cells and the skin tissues to be healthier against the symptoms of skin cancer. However, self-medication and prescription are not advisable when you have severe skin disorders or diseases like skin damage and skin cancer.
