A Non-incentivized review from a return customer

Since there was a a lot on incentivized reviews, I decided to leave one. I bought the mini duo set and it seemed to be what I needed. My skin was super stressed, changing hormones was causing random deep pimples. I never suffered from acne, and being in my 40s wanted to address sun damage and fine lines while stopping the stress induced (environmental and personal) breakouts. This did just that for me. It calmed my skin, healed it and I’ve definitely seen past breakouts spots disappear. I am an Aesthetician, and professionally speaking, this formula would not be right for someone with acne prone skin. It’s better targeted for someone who wants to fight the signs of aging while combating healing of stressed, discoloration of the skin caused by post pimple or sun damage.

To gritty to rub into the skin

I got this from the brand itself … it’s so gritty it’s unusable all over the face … so I talked to them and they sent me another one … it to is gritty!! and unusable…. I honestly do not understand how people are raving about this product …

stop with the incentivized omg

coming from someone who actually bought this (i got the duo of this and the moisturizer) and spent their own money on this, it is a hard pass. if you are acne prone please, don't even try it. I woke up every day with new acne and finally at day 30 with no results (I actually think this made my dark spots worse) I am tossing it even with it still containing product. I wear spf daily, avoid the sun as much as possible, exfoliate regularly, and have a decent skincare routine. I am 100% positive this is the culprit to my breakouts since it is the only new thing I added in. I was desperate to see results, especially after it made me get more dark spots, so I kept using it. big waste of money and now I get to deal with trying to get rid of all the breakouts and new mess it left behind. these incentivized reviews are out of hand, I hope brands realize nobody wants to touch your product when all you have is incentivized reviews.

Gentle Brightening!

I have been using this serum for about two months now and it has been such a pleasant addition to my routine! I have sensitive skin, and often vitamin C serums leave me feeling irritated. I have concerns about dark spots though, so I have been on the hunt for something that would brighten without sensitivity and this is just it! The texture of the serum is a creamy-gel, which has a minor graininess, but it doesn't detract from the experience IMO. I can layer it under am and pm moisturizers just fine and it plays well with my SPF as well. Bonus points for being fragrance free too! I have noticed gradual improvement to overall radiance, and minor improvements to problem dark spots, but those take time to tackle so I'm going to keep using and imagine I will have great results after a few more months of consistent use.

I’ve been using the product for two years. It does not irritate my sensitive rosacea-prone skin and it helps to fade dark spots.

This stuff works

I have been using for many months. Sometimes I take a break because it is pricey, but I always go back to it. If you have sensitive skin do to hormone changes as you age, this is a total game changer. I can not use Vitamin C anymore so this has been so helpful.

Works great

This stuff really works. If you stay consistent with daily use, you will notice your dark spots fade. I do go through the bottles pretty quickly, but when I’ve taken a break, my skin is not as bright.

So far so good, I’m happy with it.

I’ve been using this Mother Science Retinol Synergist for a little bit now and I actually really like it. It feels super light on the skin and absorbs pretty quick, which I appreciate because I don’t like when products feel heavy. My skin has been looking a little smoother and more even since I started using it. The packaging is also really nice, feels high quality.

A must-have!

I’ve been using this for over a year and my skin is noticeably brighter. It’s gentle enough for my sensitive skin. I use it twice a day and won’t be without it.

One of my favorites in my skincare line up!

I am obsessed with mother science products. I started using the Molecular Hero in Jan of this year & my skin loves it. My skin tone is lot more even, dark spots have lighten tremendously, & I have much more glowy skin.
