Amazon Prime Day is offering the Biossance Squalane + Growth Factor Firming Moisturizer at £39, reduced from £52, as part of the Prime Big Deal Days event. The 25% discount makes it £13 cheaper than its usual price and undercuts the £52 currently listed by retailers including Cult Beauty, Sephora UK and Space NK.
The moisturiser contains squalane, a biomimetic growth factor, cyclic peptides and encapsulated vegan collagen. Biossance says these ingredients are clinically proven to improve hydration, support the skin barrier and boost the appearance of elasticity, while smoothing the look of fine lines.
Clinical Results and Shopper Reviews
In a clinical study of 31 women who used the moisturiser twice a day for four weeks, 87% said their skin felt firmer, with visible improvement in signs of collagen loss. A separate clinical assessment involving 32 women found that 94% showed improved skin-barrier integrity after one application, according to Biossance.
The product holds a 4.5-star rating on Amazon. One shopper commented: "This is one of the first moisturisers I have used where I really noticed an improvement in my skin, with fewer wrinkles." They added: "As a woman in my 60s, I have tried quite a few brands with no real noticeable improvements. I first noticed a significant improvement on my neck, then around my eyes. This is the first time I have ever liked a moisturiser so much that I bought a second jar."
Other Customer Experiences
Another reviewer noted the product's suitability for sensitive skin, saying: "I've tried many moisturisers that didn't work for me because they irritated my skin and caused redness. This moisturiser didn't irritate my sensitive skin and left a radiant glow." However, they added: "It's not heavy, but it feels a bit sticky and takes slightly longer to absorb than some of my other moisturisers."
A further fan wrote: "This is a face cream that lives up to its claim as a moisturiser. It keeps my face feeling soft throughout the day, until I wash it off in the evening. The cream feels luxurious and has some substance, without feeling too thick or sticky."
Cheaper Alternatives
For shoppers seeking a lower price, the BYOMA Moisturizing Rich Cream (£11, Sephora) offers barrier protection with a tri-ceramide complex, bakuchiol, and shea butter. The COSRX Advanced Snail 92 All in one Cream (£24, Boots) provides plumpness and firmness using hyaluronic acid and adenosine, though it does not contain squalane.
