Why is my render noisy/blotchy?

Question

I'm new to Blender and wonder why, when I render the image, the image is noisy or blotchy.

The render result is shown below.

You can see the effect clearly at the skin area.

Can someone help me resolve this issue?

Hello and welcome :). I can only see some denoising artifacts (the color splotches). Increasing sample count (to like 500 samples) should help. — jachym michal, Jun 06 '20 at 06:52
@Xylvier Hi, just wondering, why add <br> tags when pressing 'Enter' to start a new line does the same thing? — Ray Mairlot, Jun 06 '20 at 12:11
@RayMairlot Hey, as @Lukasz-40sth already mentioned, it's helping with the formatting, and even when you press 'Enter', you won't get the clean line-break like you get with <br>. Also very much the only way (i know of) to have images sitting right when you want them inside an ordered list. — Xylvier, Jun 06 '20 at 19:26

It looks like denoising artifacts due to low render samples settings.
Go to render properties tab and increase the number of render samples.

The idea is to keep the render time low and the image as good as possible. More samples will increase the render time and quality.
