Keeping the mouth understated, lips were naturally defined and not lined with a lip pencil.
Reds, pinks and browns were still available, being fashionable at the start of the decade and coming back in towards the late ’60s.
Traditional lipsticks were mainly matte (though Vaseline could be used to add a sheen if really wanted), though there were lipsticks designed to create a sheen. Yardley’s Lip Slickers added a hint of sheen and could be worn over or under lipstick, or just on its own.
Revlon had Moon Drops, which gave lips a wet-look sheen, and Max Factor had UltraLucent Creme lipstick.
