Plant oils can be a beneficial topical treatment. Not all plant oils are equal and some may cause a reaction on skin types with impaired skin barrier.
Camellia japonica for anti-aging
Research has shown that this oil may improve skin barrier function and encourage collagen synthesis. Lack of collagen and the breakdown of elastin, dehydration, and sun damage lead to wrinkled skin.
A study showed oral consumption and topical application led to increased hydration and improved skin barrier function after a 60-day period.
Evening Primrose oil
Research has demonstrated that application of primrose oil improved hydration and barrier function in healthy skin, eczcema and moderate acne. Ingestion of this oils also improved dryness with patients who were treated with isotretinoin (Steventon, 2017).
Non plant oils
Studies have shown that this oil may improve eczema, dermatitis and psoriasis. It may also be used as a topical ointment on burns as it improves cell production and regeneration. It does not seem to irritate the skin or clog pores. This oil also shows promising results for acne scars and post dermabrasion.
