  • Changed my complexion

    Using Phase 4 along with 1-3 brings my skin back to life. I always get compliments on my face after completing all four phases. I do not find it to harsh.

  • you NEED Phase 4 !

    I had ordered the kit that had Phases 1 thru 3, but I didn't want to stop with the treatments. I had to buy Phase 4 separately. But, I am so glad I did, it gave the extra boost to my skin. Now I am using the serum and moisturizer until it is time to do the entire system Phases 1-4 again in 6 months.Thank you Beauty Bioscience for helping me help the appearance of my skin!
