Final answer:
For lighter coverage needs, a tinted moisturizer is generally used, which provides sheer coverage compared to other forms like BB cream or powder foundation, which offer more coverage.
Step-by-step explanation:
The foundation used for lighter coverage needs is generally tinted moisturizer. Tinted moisturizers provide a very sheer coverage as opposed to concealers that are meant for targeted areas with more significant skin issues and provide thicker coverage. BB cream can also be considered for light coverage, and it often includes skin care benefits such as SPF and moisturizers, but it usually offers a bit more coverage than tinted moisturizers. Powder foundation tends to provide more coverage compared to a tinted moisturizer and oftentimes is used for a matte finish.
