La Roche-Posay Mela B3 Double Dose is a day and night intensive treatment designed for mature skin. The concentrated power of Melasyl™ meets the structural support of Proxylane™, a powerful, hydrating, and collagen-boosting molecule. This combination stimulates the production of glycosaminoglycans to improve skin density and elasticity while correcting stubborn sunspots and ageing marks. By acting both above and below the skin surface, it reduces the appearance of wrinkles and leaves the skin feeling regenerated and significantly firmer.
Apply morning and evening to the face, neck, and décolleté. Also tested on hands. Avoid direct contact with the eyes. Complete your morning routine with Anthelios UVMune spf50+.

Lovely serum
I don't usually use a serum so wasn't sure what to expect from this but was really impressed. Only a small amount is needed, it absorbs quickly, used my usual moisturiser over this and then my make-up. My skin feels soft and smoother and can tell the difference from before i started using it.

Smoother, softer skin
Nice neat packaging, has all information needed on box. I liked the pump bottle, was easy to use but didn't pump even amounts out each time. It tended to squirt all over when pumping onto my finger and I felt that I ended up pumping more than I needed. The serum had a pleasant fragrance and was a pink colour so you could see where you were putting it. It had a matt effect when applied and it absorbed well into my skin. It left my skin feeling soft and definitely firmer. Unfortunately I didn't feel that it had much effect on my sun spots, maybe a little lighter but no significant change. Maybe if used over a longer period of time it will have more affect.

Good serum
I have been using this for approximately 4 weeks and although the pigmentation has faded slightly I think it would need longer.

Fabulous
I have been using the serum for around 4 weeks and have noticed a visible difference in my skin.
The pump style application is easy to use, no drips or dribbles.
The fragrance is fresh and cucumber like, then a nice easy coverage that doesn't dry sticky.
My skin feels so smooth and firmer, a real difference and I am really pleased.

Amazing skincare
It's a premium, innovative and excellent product.
After 2 weeks of use, I can see it works!
I can see the stubborn sun spot fades away while improving my skin firmness as well.
I will use it constantly and highly recommend it!

Light weight, makes my skin smoother
I have been using this for about four weeks now and I can honestly say this is effective.
This goes on smoothly, a little goes quite a long way. This is slightly pink ish in colour, is light weight and goes on well on my skin. It is non greasy and absorbs well.
I think it is quite potent so rather than using this every day, I gradually introduced this into my skincare routine.
Having used this for a sufficient period to see the benefits, I would say this is non sticky or greasy, absorbs well, makes my skin look smoother and definitely brighter and I wore this under my make up.
Additionally I did also use this at night under my night cream.
I enjoyed using this, it feels a quality product and I definitely recommend.

Brilliant
Lovely serum! I'm using this serum for a while now and I can see the difference! The spots are gently fading away. I will keep on using it and I'm sure I can get rid off them fully
Highly recommend
