Yes and no! A lotion or mousse is fine, though do a patch test and check you like the smell. Avoid spray tans, as there’s no data to say it’s safe to breathe the spray. Sunbeds should be avoided, as UV light can break down folate, prolonged use can increase risk of skin cancer, skin in pregnancy is more prone to pigmentation and you may develop darker patches. You should avoid overheating in pregnancy, which is bad for you and your baby.
