Total revenue for the second quarter of 2020 decreased $10.8 million, or 39%, to $17.0 million, compared to $27.8 million for the second quarter of 2019. Total leases revenue decreased $9.2 million, or 55%, to $7.5 million, compared to $16.6 million for the second quarter of 2019. Total products and services revenue for the second quarter of 2020 decreased $1.6 million, or 15%, to $9.5 million, compared to $11.2 million for the second quarter of 2019.
The decrease in total revenue, by geography, for the second quarter of 2020 was driven by a decrease of $8.0 million, or 50%, in international revenue and a decrease of $2.8 million, or 24%, in the U.S. revenue, compared to the prior year period. The decrease in revenue in the United States and international markets was driven by COVID-19 related lockdown restrictions and shelter-in-place orders imposed by federal, state, and local governments in most countries and markets in which we operate. In both the United States and international markets, these business closures and the resultant uncertainty negatively impacted our ability to access and sell into our customary channels. Where accessibility was possible, selling efforts were hampered by target customer concerns over economic uncertainty.
The decrease in total revenue, by product category, for the second quarter of 2020 was driven by a decrease of $9.2 million, or 55%, in lease revenue, a decrease of $1.0 million, or 13%, in system revenue and a decrease of $0.8 million, or 45%, in service revenue, offset partially by an increase of $0.2 million, or 10%, in other products revenue, which includes ARTAS® and ARTAS iX® procedure kits, Venus Concept’s Venus Skin and hair products, and other consumables. The decrease in lease revenue for the second quarter of 2020 was driven primarily by COVID-19 related disruptions, lockdown restrictions and shelter-in-place orders imposed by federal and local governments. The percentage of systems revenue derived from our subscription model was approximately 52% in the three months ended June 30, 2020 compared to 68% in the three months ended June 30, 2019. The decrease in system revenue for the second quarter of 2020 was driven by a 40% decrease in revenue from Venus Concept systems, offset partially by the contribution of revenue from the sale of ARTAS® and ARTAS iX® systems which did not contribute to system revenue in the second quarter of 2019. The decrease in service revenue for the second quarter of 2020 was driven by COVID-19 related lockdown restrictions and shelter-in-place orders imposed by federal, state, and local governments and a corresponding decline in VeroGrafters™ technician services, offset by the contribution of warranty revenue on ARTAS® systems which did not contribute to service revenue in the second quarter of 2019.
Gross profit for the second quarter of 2020 decreased $8.2 million, or 41%, to $11.9 million, compared to $20.1 million for the second quarter of 2019. The decrease in gross profit is primarily due to lower revenues caused by COVID-19 related disruptions, lockdown restrictions and shelter-in-place orders imposed by federal and local governments in countries and markets in which we operate. Gross margin was 70.0% of revenue for the second quarter of 2020, compared to 72.2% of revenue for the second quarter of 2019. The decrease in gross margin is primarily due to sales of ARTAS® systems in 2020, which have lower margins than our other systems, and inventory fair value adjustments recognized on the business combination with Venus Concept Ltd. expensed through cost of goods sold during the three months ended June 30, 2020.
Operating expenses for the second quarter of 2020 decreased $2.9 million, or 12%, to $21.1 million, compared to $24.0 million for the second quarter of 2019. The year-over-year decrease in operating expenses was primarily driven by a decrease of $5.7 million, or 56%, in sales and marketing expenses and a decrease of $0.4 million, or 18%, in R&D expenses, partially offset by a $3.1 million increase in general & administrative expenses or 26%. The year-over-year increase in general and administrative expenses was driven primarily by increased costs related to public company reporting obligations, a $3.0 million increase in COVID-related bad debt expense and additional amortization of intangible assets recognized on the business combination with Venus Concept Ltd. The Company realized more than $7.0 million, of the projected $20.0 million for full year 2020, in cost savings from the new restructuring program in response to the challenging business environment from COVID-19, which was previously announced.
