If you're someone looking to step up your dose of vitamin B3 Synergie, XCell B includes a whopping 21% - the highest potency we know on the market. If you’ve been using Synergie Vitamin B and love its benefits, then this is a natural progression - brilliant for dry, dehydrated, irritated, sensitive, oily, hyperpigmented (patchy) and acneic skin.
The younger, more powerful sister to Synergie's best selling serum. Xcell B is also supercharged with these three key ingredients: Super-antioxidant Superoxide Dismutase (SOD), to soothe the skin & protect from solar and environmental damage; Pro-Vitamin B5, to stabilise the skin barrier, soothe irritation, promote wound healing & reduce the appearance of fine lines ; and Betaine, an active that acts as a powerful water regulator to control & maintain water balance in the skin – keeping you ultra hydrated!
Mrs Ritchie's tip
There isn’t one person who doesn’t need topical vitamin B for optimum skin health. Build up to XCell B after 3 months use of Vitamin B.

Niacinamide (vitamin B3)
Stimulates epidermal ceramide (intercellular lipid) production to keep moisture in the skin, strengthen natural barrier function and improve hydration
Builds up the skin’s barrier: reduces sensitivity and combats flushing, red cheeks.
Stimulates collagen by topping up niacinamide (depleted by age) to keep fibroblasts working, for firmer, smoother skin and better elasticity.
Increases skin's immunity: by helping to prevent UVA light generated reactive oxygen species (a type of free radical), which can cause cell mutations that increase the likelihood of developing cancer. And by helping to prevent the negative impact UV light can have on the immune system (also called UV immumosuppression).
Reduces existing hyperpigmentation and inhibits transfer of melanosomes (which carry melanin pigment) to the outer skin layer.
Reduces sensitivity to help eradicate temporary, superficial imperfections.
Reduces sebaceous oil production and the subsequent occurrence of acne.
Panthenol (vitamin B5)
A water-binding humectant that partners brilliantly with niacinamide to add moisture into the skin, improve softness and reduce the appearance of fine lines.
Superoxide dismutase (SOD)
An enzymatic antioxidant, bioidentical to SOD found in human cells. SOD soothes the skin and helps combat against photoageing, leaving the skin healthy and more radiant.
The formulation also contains Sodium PCA and betaine, powerful skin hydrators that draw moisture to the skin, protect the skin barrier, reduce skin irritation and improve skin healing.
