Wrinkles, pimples, brown spots, dry skin and rashes.

Many women - and maybe men - would shout for joy if there was ever a magic bullet that could eliminate those skin woes.

Over the years, facial oils - including jojoba, rosehip and tea tree - have become popular because they are touted as "natural" ingredients that can revitalise the skin.

Most of these oils - sold at many cosmetic counters and natural food stores - are often said to be good moisturisers.

Some have other claims like the ability to lighten scars (jojoba oil), reduce acne (tea tree oil) and plump out wrinkles (sweet almond oil).

But can we trust them to work?

Dermatologists that Mind Your Body spoke to are doubtful of the accuracy of such claims.

Dr Wang Yi Shi, a consultant dermatologist at Changi General Hospital, said: "I will not recommend facial oils for anti-inflammatory and moisturising purposes as there are many other superior and better studied products available."

Agreeing, Dr Ang Chee Beng, a consultant dermatologist at Ang Skin and Hair Clinic, said: "The studies concerning such ingredients are not robust.

"There are a lot of theoretical benefits based on anecdotes. Their use in cosmetics and over-the-counter products is fine.

"But in order for them to be prescribed as a medical-grade compound - like retin-A or vitamin C - there needs to be bigger studies to prove the benefits."

Both Dr Ang and Dr Wang do not recommend the use of facial oils.

"There is no clear evidence that they are essential to a person's skincare routine," said Dr Wang.

Facial oils aside, a general tip for good skin is the use of an effective sunblock.

"This prevents ageing changes caused by sunlight and pigmentation problems," said Dr Ang.

Still, for those who want to try facial oils, there are two groups that should tread carefully in doing so.

Dr Chris Foo, a dermatology specialist at Raffles Hospital, said: "Individuals with oily skin who are prone to acne breakouts should take extra care when using facial oils."

Said Dr Wang: "People with underlying skin conditions such as eczema or broken skin should avoid using facial oils. They are more prone to developing an allergic reaction to the plants or fragrances present in the oils."
