Exceeded my expectations

This product has transformed my skin. I’ve always had large pores and oily skin due to genetics. It has made my skin so incredibly soft and even toned. My pores are smaller, my skin is not as oily. And the results were very fast. I cannot recommend this product enough.

I've been using the Flower Acid Exfoliating serum from Mara semi consistently for 2 weeks now. I only use it at night and haven't had any issues other than it does have a tiny sting when you first apply. I have sensitive skin and it hasn't caused any reactions. I do feel like I notice my skin is softer on the mornings after I've used it.

A Must-Have!!

The was my first time trying the flower acid algae serum by MARA & I’ve been loving it. It’s paired great with my skincare routine. I have sensitive and dry skin, but this serum hasn’t caused me any issues. I would highly recommend!

Good

The MARA Flower Acid Algae Serum gently exfoliates, brightens, and smooths the skin while keeping it hydrated. It feels luxurious and nourishing, leaving skin soft and glowing — just be sure to use sunscreen, as it contains exfoliating acids

Smells Bad!

Disappointed in this product. It has an awful scent. I really wanted to like this but the smell, I just couldn’t use it anymore.

OBSESSED!!!!

This is such a beautiful serum. I am so excited that I found this brand! I ALWAYS prioritize clean beauty over anything else and this brand is surprisingly really clean and I love that. Not only is it clean, it is effective! Literally my new holy Grail serum!!! It leaves my skin soft And it doesn’t pill under make up or sunscreen either. I am OBSESSED

he is great

Review for Flower Acid Algae Serum I’ve been using the Flower Acid Algae Serum, and it’s been a wonderful addition to my skincare routine. The serum has a lightweight texture that absorbs quickly without any stickiness. My skin feels smoother, hydrated, and looks noticeably brighter after just a few uses. It’s gentle yet effective, making it perfect for daily use. Highly recommend for anyone looking to improve skin texture and glow!

The results I experienced were the softening of fine lines, my skin texture was smooth, noticed hyperpigmentation was starting to diminish. Overall, a subtle bit drastic difference in my skin but healthy looking.

Great for rosacea skin

Works fast to resurface skin overnight. Expected discomfort in the beginning, but you can build your tolerance to use every other day. My skin is smoother, softer, and hydrated when I wake up. My only buts: formula dries out in pump (even when I use this regularly) and it doesn’t smell the best.

instant results!

glad i took a chance on this. i'm allergic to niacinamide so it's hard finding brightening/smoothing products without it. i noticed an improvement in texture after the first use! stings a little but it's not too bad.
