Skin naturally uses antioxidants (AOs) to protect against photo damage. Sun protection can be enhanced with effective formulations of topical antioxidant. Recently, consumer and media attention has focused on virgin coconut oil (VCO) as it was claimed having several beneficial effects for skin on its topical or systemic usage. We investigated the VCO protection against UVB induced erythema and pigmentation. The value of mean L*, a* and minimal erythema dose (MED) of 22 healthy volunteers were determined as the basic value. The next day, their back, which treated with VCO within 30 minutes and untreated one, were exposed to 1, 2, and 3 times of MED of UVB irradiation. Erythema and pigmentary response were accessed 24, 72, and 144 hours after exposure for the value of L* and a*. The significance of mean L* and mean a* were analyzed by Independent T-test with p value < 0,05. The p value of mean L* and mean a* after 24, 72, and 144 hours of 1, 2, and 3 times of MED of UVB irradiation were L*1MED: 0.387; 0.753; 0.587, 2MED: 0.823; 0.778; 0.997, 3MED: 0.667; 0.553; 0.760, a*1MED: 0.783; 0.148; 1.000, 2MED: 0.842; 0.786; 0.847, 3MED: 0.937; 0.631; 0.995. The claim that VCO having protection against UVB induced erythema and pigmentation was not proved.
