Coconut oil has been touted as a natural alternative to sunscreen due to its natural SPF of 4-5 and antioxidants that help protect the skin from harmful radiation from the sun. However, this belief is not supported by scientific evidence. A 2009 study suggested that coconut oil can act as sun protection with SPF 7, but this study was conducted in a petri dish, not on human skin. In fact, coconut oil has a very low SPF of 7 and only blocks 80% of UVB rays, which is much lower than traditional sunscreens that block 93% or more.
Here are some positive and negative aspects of using coconut oil as sunscreen:
Positive:
- Coconut oil is a natural ingredient that does not contain harmful chemicals.
- It can be moisturizing and high in antioxidants that help protect the skin from harmful radiation from the sun.
- It can be a fun DIY project to prepare for summer and can save money.
Negative:
- Coconut oil has a very low SPF of 7 and only blocks 80% of UVB rays, which is much lower than traditional sunscreens that block 93% or more.
- It is not completely waterproof and needs to be reapplied frequently if used at the beach or a pool.
- It is not the high SPF (sun protection factor) that is generally recommended for long-term sun exposure.
- It can cause skin irritation or allergic reactions in some people.
In conclusion, while coconut oil can offer some natural sun protection, it is not a substitute for sunscreen and should not be relied on as the sole form of sun protection. It is important to use a proper sunscreen that provides adequate UV-absorbing or UV-blocking protection to be effective.
