Spider veins and simple varicose veins are safe to sugar over, but with enlarged varicose veins, we do not typically recommend performing sugaring treatments due to associated medical complications. 

As long as veins are not warm to the touch or the client does not experience discomfort which applying slight pressure, perform a patch test to decide if treatment is acceptable. 

Phlebitis is a painful inflammation of the veins and sugaring treatments should never be performed. 

Bruises might make an area more sensitive and painful, might also be related to a blood disorder. 

Lesions are due to any abnormalities or damage the tissues underneath the skin, they can be caused by diseases such as tumors, physical trauma or abscesses, acne or cold sores. 

Bruises and lesions should not be treated, especially lesions that entail breaks in the skin.

New unhealed scars and sunburned skin need time to completely heal without being disturbed. Skin is very sensitive and any sugaring treatment can irritate and set back  the healing process. 

Skin tags or skin growths often are located underarms and bikinis area; you can safely sugar around a skin tag

You should not treat warts because they have a high risk of spreading during the sugaring process. Treat raised mole with caution. 

Skin on a mole is no more prone to bleeding or tearing than any other healthy skin, but it still might sting more when tweezed. 

Moles rarely turn into melanomas, skin cancer where the melanocytes that produce the melanin pigment become cancerous. 

Never extract hair from the client’s deep inner ear, this could cause too much pressure that could potentially cause damage that leads to balance and hearing problems. 

Careful sugaring men’s beards because of the network rooting system such that the roots are intertwined beneath the skin.
