When the skin is exposed to UV light, three effects can happen:

1. Immediate tanning – the desired result

2.Delayed tanning -(where more color surfaces after 24 hours for a darker tan) – a desired result

3. Tanning Erythema (Te) – SUNBURN!! – an undesirable result.

Yes and No. You can use any indoor lotion outdoors but not the other way around. Indoor lotions provide great additives that will produce great results but be careful
not to over do it! Indoor lotions do not have any SPF factor in them so your risk of burning due to overexposure will not decrease. Outdoor lotions may not be used in tanning units in general, and they won’t allow your tan to develop well either.

They do not produce melanin and will burn easily unless you protect them with lip balms or sunscreen.
