review my skincare formula and provide ways to improve efficacy while keeping price affordable

Job ID: 31066954

Budget: $30 – $250 USD

Looking for someone to revise my formula for an oil product. I have been using this product for one and I don't think there has been much of a difference, so I want to know what I can do to improve my product in terms of efficacy. My product claims are the following:
1. reduce irritation, itchiness, redness
2. reduce razor bumps
3. sooth skin
4. reduce ingrown hair
5. improve hyperpigmentation

It is important to note that I am looking to create a cost-effective product (aiming to retail for less than $10), so this is also something to keep in mind when reviewing.

Must be okay in signing NDA
