As always, Sean gives great advice and I agree with his comments! I would also say that you have a great foundation and layout here.
Something that would take your product to the next level would be to define your brand identity. This will help create a lot of trust. When I glance at your page I get a mix of modern and natural and there are many different fonts and colors used, stock photorgraphy (avoid if possible), and mismatched icons. I would narrow this down - pick a headline, subheadline, paragraph fonts, pick your primary and secondary colors, etc.
For this product - I would suggest going with a natural feel. People are more particular about what they put on their faces - give them the feeling that this is a safe, healthy, good product to put on your face.
I think Prose does a great job of projecting a natural “vibe”: https://prose.com/products/custom-shampoo
There are quite a few good brand builders to assist you to get started:
A few other suggestions are listed below:
- Add a favicon
- Add photos of the people who give the testimonials
- Use a accordion for your FAQ section - it will shorten your page and give users control of the information they want to see
Hope this helps! Happy to provide more clarity on any of these items!
