I purchased the Biotherm Skin Ergetic Day for normal to combination skin to replace my Boots No7 Protect & Perfect Beauty Serum. Skin Ergetic is advertised to reduce the signs of fatigue, smooth, plump and moisturize and give you a radiant-looking complexion. I found that after a few days of using the moisturizer I did notice my skin looked more plump under my eye area and I noticed my complexion looked fresher. Skin Ergetic is a creamy light gel with a citrus scent. I found it very pleasing and it did not bother my allergies. The drawback is the price. I purchased a 50ml jar for $50 CAN (a great deal more expensive than the Boots No7). Even with it's steep price I will continue using it because of the noticeable improvement in my skin's appearance.
