I've been adjusting my format slowly but regularly. i started with a plain statement of my thoughts and now I'm working my way up to a stable format.
1. i start with a brief introduction
2. then I describe the texture
3. then I move to the characteristics of the product (fragrance free, alcohol free, ...)
4. then I cite the key ingredients
5. and then I share my thoughts
you can add your own sections. some people like to give ratings. others have a repurchase value section, where to buy section... etc
it's a process and we all are still learning, so take your time and good luck ❤
