Carrot Sun products do not contain any SPF (sun protection factor), but can be used in conjunction with SPF containing lotions without interfering with their effectiveness. It is recommended that an SPF-containing cream be applied to the skin prior to the application of Carrot Sun products, or that you have a base tan prior to their use, in order to tan safely and responsibly. If you have any skin conditions or sensitivities, or are gluten intolerant, please consult your GP or dermatologist before use. The Carrot, Papaya, and Tropical Fruit varieties of Carrot Sun creams contain henna, which may stain garments. Carrot Sun products are can give fantastic tanning results, but in order to achieve a healthy, glowing, and beautiful tan, it is essential to tan responsibly. Only increase exposure times to the sun or on sunbeds slowly and gradually over time as you build up your tan.
