Skin-Renewing Serum for Post-Acne Healing

Biologique Recherche Serum Iso-Placenta is a powerful regenerating serum designed to repair skin compromised by breakouts, blemishes, or acne scarring. This targeted treatment visibly reduces post-acne marks, redness, and uneven skin texture while helping to restore a smoother, clearer complexion.

Formulated with a biomimetic placenta complex, this serum mimics the skin’s natural repair factors to support cellular renewal and recovery. Carob Seed and Scotch Thistle extracts enhance the skin's healing response, stimulating regeneration across all layers of the epidermis.

With consistent use, skin damaged by acne appears visibly healthier, more even-toned, and calm. It's the ideal solution for anyone looking to fade blemishes and restore the skin’s integrity after inflammation.

Skin Concerns Addressed:

Post-acne marks and discoloration
Acne scars and pitted texture
Redness and sensitivity from past breakouts
Weakened or damaged skin barrier
Uneven skin tone or rough texture

Key Benefits:

Repairs and rebuilds skin damaged by acne
Fades acne scars and blemish marks
Calms redness and irritation
Smooths skin texture and evens tone
Strengthens the skin barrier for long-term resilience

Who Is It For?

Ideal for acne-prone skin, those healing from breakouts, or anyone experiencing scarring, redness, or uneven texture after acne. Gentle enough for sensitive skin needing regeneration and barrier support.

Sizes:
30mL / 1oz
8mL / .3oz

HOW TO USE

After properly cleansing with a cleanser and prepping the skin with a toner apply Serum Iso-Placenta (you may use it as a spot treatment), follow with moisturizer and SPF.

How to open serum:

Helpful tip to maintain the integrity of the product, Biologique Recherche serums have a uniquely customized applicator that must be manually secured to the bottle. We understand that this could be a bit tricky, especially if you are opening a serum for the first time.

Reviews

Magical

"My mom says I look like CGI the whole BR range has transformed my skin like nothing else."

— Kaitlin D. (5/5)

NOT WORKING FOR ME

"I have some post acne hyperpigmentation on my cheeks, been through 3 big bottles of isoplacenta paired with creme isoplacenta & creme aux acides de fruits. my skin is not any better, i dont know why, because i love BR."

— Sundas T. (3/5)

Broke me out

"Tried this intermittently for months as I kept breaking out with use. When I stopped using it, my skin calmed down. This caused bad breakouts and also had a strong smell. I have several BR products, which I love. But, I would skip this one. I shouldn’t have bought a full size initially."

— Sarah K. (1/5)

Searched a long time for this

"I love this I have had adult acne along my jaw for 15 years. 3 weeks of this and it is gone and my skin looks great. This did what dermatologists could not accomplish. I don’t think you will be disappointed."

— Mary K. (5/5)

This stuff is great-- the ISO formula has ALCOHOL :(

"This is one of the best serums on the market. I have very sensitive skin that is prone to acne, dryness, hyperpigmentation. . you name it. I'm VERY disappointed in BR, as I love the placenta line, and the new ISO products have WAY WORSE ingredients in them. The ISO Serum Placenta has Alcohol Denat, which is not good for your skin. the ISO Creme Placenta has plant oils, which my skin cannot tolerate. BR, why did you have to do this to your formulas?????"

Pure gold

"I love the placenta serum! I have some old scars and dark marks on my face, this really did some magic on my skin! I also like it for around my eyes. It improved the under eye skin and I have less darkness there."

— Sierra (5/5)

unusually exceptional

"super watery consistency, odd smell, but so effective! now i love the smell because i know that i am giving my skin something it loves. has reduced under eye circles in a few weeks, which is a small miracle. my adult acne prone fussy skin is looking clearer and feeling softer with the use of this serum. i use it after p50 1970."

— Daina (5/5)

Loving It

"I'm about a week-and-a-half into using the Placenta Serum and have already noticed a huge change in terms of fine lines and a lightening of dark marks and scars on my face. I have adult acne and a bad post-inflammatory response that leaves pimples on my skin for too long. I saw a difference almost immediately!"

— Annie G. (5/5)

This is a new product

"This is a new product for me in the Bioloque line. I am 53 with sunspots and circles under my eyes. I can definitely tell a difference. Tip with serum, I mix a few drops with my Vitamin C gel. This way I get great coverage."

— Holly S. (5/5)

My only complaint? That it doesn’t come in a JUMBO size! HG serum, LOVE!

"Started with the tiny bottle (so nice having options to try serums before making larger investments!) and I’m now on my 2nd “big” bottle! I love this potion! I only wish it came in an even larger size because this and Iribiol are my must haves! I will ALWAYS reorder! Thank you to the wonderful Rescue staff for ll the top-notch assistance! You have a life long customer here :)"
