Nice!
I like the Ursa Major products. My skin feels healthy and balanced. I like the ingredients in the retinal serum.

Lunar Bloom
It got a poor rating by Yuka as it contains Phenoxyethanol. I thought this was a clean line of product so I was very disappointed. I did not use it.

The first product that worked in YEARS
I have had uneven skin tone and lots of blocked pores on my chin for YEARS. Nothing I have ever tried did anything to ameliorate this, not even from some very expensive competitor (Rodan & Fields). I have been using this serum for about 6 weeks (one bottle's worth) and I am seeing a lot of improvement! I use it twice a day and even with my sensitive skin, have seen no adverse reactions...just improved skin tone. Hooray!

First Retinal that's worked for me!
I've tried a few 'natural' retinal and retinol serums and either I didn't notice any difference or they dried my skin out too much. I am applying this over a moisturizer in the evening 3x per week and I've noticed my skin more luminous and even without it drying out too much. I'm excited to see continued results!

So far so good.
I usually react negatively to retinol and retinal product. I have been using this every other night without irritation and think my skin looks a tiny bit better.

Need some more time
I like how the serum soaks into my skin, it’s not greasy nor does it just lay on top. It definitely soaks in. I need to give it more time to notice significant results.

Magic in a bottle
I waited a few weeks before reviewing the Lunar Bloom Retinal Serum because I wanted to truly see results first. I’m blown away by how quickly I’m seeing a more youthful glow to my skin. I use it daily at night and never experienced any discomfort on my sensitive skin. It goes on similar to the Mountain Glow Serum (which I use daily in the mornings and love!). It’s silky and soothing, and layers well under the Alpine Rich Cream, and it does not irritate my eyes. I have some fine lines and sun spots on my aging skin, and after a few weeks of using the retinal, I’m noticing a softer texture to my skin and a definite fading of lines and spots. I’m almost 47 and am often told by strangers that I look much younger than my age, which I 100% attribute to my Ursa Major skincare routine and products. I’m excited to see how adding the Lunar Bloom Retinal Serum at night continues to keep my skin glowing as I age!
