Nowadays, we work just about anywhere.. in our homes. From our home office, to the living room couch, to even our bed sometimes. More and more people are working from home and thus use their portable laptops any kind of way. But actually putting them on your lap could do some damage.
The prolonged placement of laptop on the thighs results in the thermal build of around 44 degrees of heat to which the skin responds by developing persistent redness and pigmentation. This has been reported in medical literature between 2004 to date.
Some Harmful effects
"The skin develops a patch which is mottled (caused by local hemostasis — stagnation of blood) and later becomes reticulated erythema (patchy striped erythema) leaving behind pigmentation," says Cosmeto-dermatologist Dr Swati Srivastava.

Treatment & Remedies
First of all, identification of the root cause, i.e., the source of the heat, needs to be identified. If it is excess duration of laptop usage, it should be cut down. Also, direct contact of the laptop and the skin should be avoided by placing a barrier in between. Many online retailers have laptop coolers available. The skin change, if detected early and is mild in nature, can settle on its own without treatment. For persistent redness, anti-inflammatory creams can be used.
For pigmentary changes, addition of topical tretinoin (a drug related to retinol or vitamin A) cream may be mandatory. In some cases, one may require laser therapy.
