What Are The Key Ingredients in No 7 Line Correcting Booster Serum?
In order to determine how well No 7 Line Correcting Booster Serum performs, we’ll have to evaluate the key ingredients in this formula. Let’s get started.
Matrixyl 3000 is a trademarked peptide composed of the matrikines palmitoyl tripeptide-1 and palmitoyl tetrapeptide-7. These two peptides work synergistically to restore and maintain the skin’s youthful appearance by signaling to cells to produce more collagen. Numerous studies have proven the anti-aging and anti-wrinkle efficacy of Matrixyl 3000.
For example, a clinical study involving female participants demonstrated that after just 2 months of treatment with Matrixyl 3000, the area occupied by deep wrinkles was reduced by 45%, and the skin’s tonicity increased by nearly 20%.
In a separate 2 month clinical study conducted on a panel of men, the anti-wrinkle efficacy of Matrixyl 3000 was confirmed. As the wrinkle volume decreases (-17.1%), the spread angle increases (+5.4%), which leads to a reduction of the surface occupied by deep wrinkles of nearly 30%.
Another peptide used in No 7 Line Correcting Booster Serum is Acetyl Dipeptide-1 Cetyl Ester, which goes by the trade name “Calmosensine”.
According to the manufacturer, Calmosensine is a “messenger of tranquility and muscle relaxation”. It works via stimulating the skin nerve cells to release met-enkephalin, which is an opioid (i.e. relaxing, pain-relieving) messenger molecule.
Ultimately, this means Calmosensine signals skin cells to relax, thereby soothing skin and reducing irritation. Furthermore, it’s claimed to relieve tension to help prevent the onset of wrinkles and expression lines.
Lastly, No 7 Line Correcting Booster Serum includes humectants like glycerin and butylene glycol. These ingredients attract moisture and hold that moisture in the upper layers of skin so that skin stays hydrated.
How to Use No 7 Line Correcting Booster Serum?
Use both morning and evening as part of your daily skincare routine.
- Twist silver base to unlock and press to dispense desired amount
- Using the precision applicator, apply directly to lines & wrinkles
- Follow with your usual serum and moisturizer
To use No7 Line Correcting Booster Serum as a booster, mix one or two drops into your moisturizer, eye cream or foundation.

No 7 Line Correcting Booster Serum Reviews
No 7 Line Correcting Booster Serum reviews on the brand’s website are mostly positive, but there aren’t very many reviews (only about 100). So we went over to Amazon.com to evaluate customer reviews.
On Amazon, No 7 Line Correcting Booster Serum reviews average to 4.4 out of 5 stars after more than 3,000 customer reviews.
There are many 5-star reviews for No 7 Line Correcting Booster Serum from customers who love that it moisturizers while helping to reduce the appearance of lines and wrinkles.
For example, one review says, “I use this every night and I’m loving it! It’s been working for me. I use it under and around my eye. I noticed the lines have been slowly disappearing after using it for 2 months.”
And another 5-star review says, “Great product and very moisturizing! I definitely notice the difference between the days I use it and days I don’t. The lines around my eyes are definitely diminished when I use this regularly.”
However, there are a handful of negative No 7 Line Correcting Booster Serum reviews, which are mostly from customers who were disappointed that they did not see the results they were hoping for with this serum.
For example, one review says, “Expensive but I was willing to invest to see a positive difference. No difference, facial wrinkles still there, not even lessened!”
A similar 1-star review says, “Don’t waste your money on this product. It is no better than a less expensive moisture cream or plain Coconut Oil. My wrinkles are just as visible as they were before I used it! I am very disappointed.”
Overall, we think that No 7 Line Correcting Booster Serum is formulated well, but we typically prefer anti-aging serums that target multiple signs of aging.
- Matrixyl 3000 has data to support its ability to reduce lines and wrinkles
- Fragrance free
- Many positive No 7 Line Correcting Booster Serum reviews
- No 7 is cruelty free
- Since this formula only targets lines and wrinkles, you’ll have to use other products for dark spots, uneven skin tone and texture, enlarged pores, etc.
What Are Some Alternatives to No 7 Line Correcting Booster Serum?
If you’re looking for skin care products to address the signs of aging, one brand we recommend is Formulyst. Formulyst maximizes the use of powerful ingredients and minimizes the use of superficial ones, resulting in clinically advanced skin care solutions that help promote healthy, more youthful-looking skin.
For example, Formulyst’s Anti-Aging Concentrate can help to address multiple signs of aging at once. This serum contains natural ingredients like squalane, green tea, vitamin C, and vitamin E, which provide powerful antioxidant activity to protect the skin against environmental free radicals that are known to degrade collagen. In addition, this serum contains Matrixyl 3000, a peptide complex that works to restore and maintain the skin’s youthful appearance by signaling to cells to produce more collagen.
Another brand that balances the power of plants with cutting edge science is Carrot & Stick. Not only is Carrot & Stick good for your skin, it is also good for the environment as the formulas skip harmful chemicals commonly found in skincare products.
