Benefits

Clinically proven to:

– to instantly boost hydration

– to reduce the visible depth of wrinkles by up to 85% in just 2 weeks

– achieve a strengthened skin moisture barrier

Formulated With

GHK-Cu Longevity Matrix: A blend of wrinkle-targeting peptides, engineered to help soften the appearance of existing lines – and slow the appearance of new ones.Our matrix combines copper tripeptides, niacinamide and vitamin E, ingredients known to act as antioxidants against daily stressors like pollution, to help support skin’s natural defence. More resilience means skin is better equipped to slow down the visible signs of aging, and maintain a smoother, more youthful appearance for longer.

+ Phyto-PDRN + NMN: A powerful combination of vegan PDRN, a polynucleotide that is known to help create an optimal environment for surface renewal and supports the skin barrier, and NMN, a molecular pre-cursor to NAD+ known to drop dramatically with age.

+ Tri-Ceramide Complex: Our carefully researched barrier-boosting complex designed to mimic and replenish the essential lipids found in the skin. Formulated with 3 key components of the stratum corneum (Ceramide NP, Cholesterol, Fatty Acids) used in the golden ratio to help replenish the skin barrier and support natural moisture levels, so that skin functions at its best every day.

Reviews

Sadly, I came out on

"Sadly, I came out on a rash after using it for just 2 days. The rash cleared as soon as I stopped using this cream. I have multiple other Byoma products and never had an issue before!!!. I love Byoma products but I must admit that the packaging whilst looking very attractive it is nearly impossible to get the last 30-40% of the products. Please fix this issue - thanks"

— Titus G. (3/5)

Probably the best serum there is!

"The ingredients list on this serum is jam packed with all the peptides your skin needs. The price point is amazing too. I’ve been using it for two weeks and can already see a difference in my skin especially on my décolleté. I genuinely love Byoma and have swapped out all my high end expensive products for this brand."

— Catherine B. (5/5)

So far so good

"I’ve been using this product at night for a couple of weeks now and it has made a difference to my skin. Pores are reduced and skin seems smoother/softer. I haven’t had a break out or irritation, which I’ve had from other brands so, so far so good. I will buy again as long as I keep noticing an improvement. Very happy with product."

— Deborah D. (5/5)

Love it

"As a woman of a certain age (60) my skin can feel and look dull and tired. I was using the medik8 serum which was great but very expensive, I love how my skin feels and looks after using yours."
