A plumping hyaluronic serum for wrinkles and loss of firmness
La Roche-Posay Hyalu B5 Serum is a hydrating anti-wrinkle serum for all skin types, including sensitive skin, that is losing firmness and elasticity. The current formula combines four types of hyaluronic acid that hydrate different layers of the epidermis for a plumper, smoother look, with vitamin B5 to support skin barrier repair and madecassoside to soothe. Adenosine completes the formula to smooth the look of wrinkles. The skin feels tighter right after application, and with regular use it looks firmer, more elastic and more supple.
The texture
A fresh, lightweight serum that absorbs in seconds and leaves no stickiness, so it layers easily under a moisturizer or a sunscreen. It has a light scent.
Who it suits
- Skin showing wrinkles and a loss of firmness
- Dehydrated skin that looks dull or lined
- Sensitive skin that wants an anti-ageing step without retinol
- Morning and evening routines
Worth knowing before you buy: the formula contains alcohol denat. and fragrance. Very reactive skin may prefer to test it on a small area first, and can follow with a soothing balm such as Cicaplast Baume B5+ for extra comfort.
How long a bottle lasts
Used morning and evening with a few drops, the 50ml bottle lasts around three months.
