Now that you know what guava seed oil is good for, let me tell you more about the guava’s composition, skin benefits and how to incorporate it into your skincare routine. 

What is Guava?

Psidium guajava or guava has been cultivated for a long time and spread to other parts of the world. However, many believe the tree is indigenous to tropical and subtropical regions of America. Guava shrub or tree can reach from 1m to 6m in height. It is characteristic of its reddish-brown bark and oval shape leaves reaching up to 15 cm as they spread over the treetops. 

The guava fruit range in size, shape and colour, depending on the tree variety. It can be as small as tangerine or as big as a grapefruit. The sweet, juicy white, yellowish or pink pulp of guava makes tasty sweets, snack bars and juices. 

The yellowish, bean-like shaped guava seeds were treated as waste and disposed of without considering an environmental effect. However, that is changing. Guava seeds produce oil that is beneficial in the production of cosmetics due to their unique chemical composition. Hence, in the future whole of the fruit can be used, minimising the negative impact on the local environment. 

Habitat

Common throughout tropical and subtropical parts of South America, the tree is usually found on the forest edges, natural forests, agricultural areas, and river banks. However, Psidium guajava is an invasive plant. It can cause havoc for native vegetation when introduced to a new environment. The plant even made it to the Global Invasive Species Database (GISD 2010). 

The guava uses

  • Rich in Vitamin A, C, iron, and calcium, guava fruit is a source of essential nutrients in the indigenous population’s diet. The local people turn the fruit into tasty ice cream, jam, juices, jellies and other culinary treats. 
  • Rich in linoleic acid (Omega 6), guava oil is used in the cosmetics industry to produces soaps, shower gels, massage oils, and moisturisers. 
  • Guava is a well-known plant widely used in folk and traditional medicine. It proved helpful in treating diarrhoea, hypertension, wounds, fever, ulcers, diabetes, and rheumatism; it is also effective pain relief.
  •  Guava wood makes good tool handles, poles, toys and fences.

Psidium guajava or guava is also a popular bonsai specimen.

Some of the notable compounds found in the oil include:

Fatty Acids: Linoleic, oleic, palmitic and stearic acid found in guava oil help protect the skin’s natural barrier, fight inflammation, hydrate, and restore its elasticity while keeping the skin supple. 

  • Linoleic acid (C18:2) is an essential fatty acid Omega 6 moisturises the skin, supports the skin’s barrier function, shields the skin from UV radiation, and can reduce hyperpigmentation. It helps treat acne, eczema, psoriasis, dry and sensitive skin.   
  • Oleic acid (C18:1), Omega 9, is a monosaturated fatty acid that softens the skin, stimulates hair growth, and eliminates dandruff. The acid has antioxidant properties, strengthens the immune system, and prevents inflammation and joint pain.
  • Palmitic acid (C16:0) is a saturated fatty acid that helps the skin restore its natural barrier structure. It is a best friend to dry skin and hair. 
  • Stearic acid (C18:0) is a saturated fatty acid with skin-cleansing properties. It frees the skin and hair from excessive sweat and sebum. 

Bioactive compounds:

  • Lycopene is a non-provitamin A carotenoid found in fruit and vegetables, giving them the characteristic bright red colour. It is an antioxidant that protects the skin from sunburn by increasing the basal defence against UV light-mediated damage. Additionally, it slows down damage to collagen fibres, thus preventing the skin from losing firmness and slowing skin ageing. Furthermore, Lycopene reduces the appearance of wrinkles and keeps the skin soft and elastic.
  • Vitamin C (Ascorbic Acid) is an important antioxidant that protects cells from oxidative stress, promotes wound healing and improves skin hydration. It also participates in collagen formation and is effective against pimples, blackheads, and acne.
  • Iron is a mineral essential for maintaining healthy skin, hair and nails. Moreover, iron oxide plays a crucial role in oxidative stress and photo-induced skin damage
  • Zinc is an essential mineral with many body functions. In skincare, oxides such as zinc protect the skin from photodamage by reducing the UV radiation that enters the skin. Furthermore, zinc is beneficial in the relief of dandruff, seborrhoeic dermatitis and promotes the healing of minor irritations.

Its astringent ( it will shrink skin tissues, reduce pore size, tighten loose skin) and non-comedogenic (it won’t clog pores) qualities make it a fitting ingredient for oily and acne-prone skin. 

It helps reduce the appearance of wrinkles

The antioxidant properties of guava seed oil can protect the skin from free radicals and premature ageing. Free radicals are reactive molecules generated due to environmental factors, such as pollution and UV rays. Antioxidants can neutralise free radicals and prevent oxidative stress. 

Guava seed oil’s antioxidant properties also help fight the UV-induced loss of collagen in the skin, thus restoring firmness and helping to reduce wrinkles.
