Adafruit SCD-41 - True CO2 Temperature and Humidity Sensor - STEMMA QT / QwiicThe SCD 41 is a photoacoustic "true" CO2 sensor designed to measure the CO2 concentration (in parts per million, PPM) in ambient air. Unlike sensors like the SGP30, which approximate CO2 levels based on VOC gas concentration, the SCD 41 directly measures CO2, making it highly accurate but also larger and more expensive. It is ideal for environmental sensing, scientific experiments, and air quality studies. This sensor uses a different measurement

I have so many liquid and powder foundations, you name it I've tried it! They all settle into the pores on my nose to the point where sometimes I almost feel it looks better without makeup. I'm not usually a bb cream person because I have quite oily skin, but this stuff is magic. It is very similar to a silicone based primer, but works better. It has surprisingly good coverage, I just add another layer to problem areas, and spot conceal if needed. However, this doesn't have the best staying power, but none of my foundations ever stay on anyway! So I set it with powder, either loose or even a light layer of a powder foundation and it looks very nice. Also sometimes if I want to wear a different foundation I'll use this just on my nose area sort of like a primer. I am 28 with oily skin, minor breakouts, and an nc20 with a lot of redness, which this evens out, for reference.

Great Substitute for Dr. Jart Dis-A-Pore

I did a ton of research after my tried and true Dr. Jart's Dis-A-Pore was discontinued. There are rumors that it will return but I'm reluctant to believe that. This product was recommended as a substitute after much research and I thought it was worth a shot. This is the real deal. I was a light-medium with dr Jart and I am the lighter version of this product. I love how it feels on my skin, it's like a matte velvet. I am definitely acne prone even as I approach 30 and redness occurs often. I'm very pleased with how natural and yet polished this product makes me feel and look. My only complaint would be that $30 is pretty steep for 1 ounce of the product. However, it works and that's what is most important to me! Update: I've had this product for almost 6 months and wear it almost every day - I would say a little goes a long way and that $30 is totally reasonable considering how long it has lasted!

Great lotion for very dry skin

Style: Updated Formula

I had a laser done on my face and the products they gave me weren't working. This came highly recommended so I gave it a try. I'm very glad I did! It moisturized my face really well without appearing greasy. I used the rest when my face got dry from winter (in th midwest). Felt very rich and smooth. Medium thickness.
