First Impressions, will update in a couple weeks.
-Initial impression is it's a good value. Product box is quite sturdy; the squeeze tubes and jar come in foam inserts, so broken or split containers are highly unlikely. The glass jar is wrapped in plastic as well as a plastic cap inside lid to prevent any leaking of the Eye Cream. All 3 squeeze tubes have foil seal under flip cap, again protecting from leakage. I love that as I've had different products arrive exploded from heat exposure. -I've only use the products once as of this review, but I like the light feel and smells of all 4 products. I'll update this review or write a new separate one for more in depth review in a couple more weeks after I get some use out of them. -Overall, I like everything. The Face Scrub isn't super grainy, but it took off the flakey skin without over exfoliating, gentle yet thorough. I'd only use it once a week. -Foaming Cleanser lathers well and doesn't drip down the face if it's not super wet. No strong smells and removed the oil I get on my face and ears from the coolant at work with no issues or extra scrubbing. -The Moisturizer has a light smell and a slight cooling effect, kinda like eucalyptus, very nice and it's not oily or greasy. -Lastly is the Eye Cream. Super light and not greasy and it doesn't burn, which I've had other products do on the past. A little goes a long way.

Smells great, works well! ❤️
Made a basket for my husband, smells so so good!!! He loves new face creames and he says this stuff feels great. He struggles with black heads and I already saw improvement in his skin texture in just 2 washes.

Good product, but needs a little work to be perfect.
Honest product review here: It's very close to being perfect. 1. The tubes are a very good size, I get annoyed with products that cost a lot and the tubes are the size of my fingers (Tiege). 2. The foaming cleanser is great, no complaints. My face feels very clean. 3. The facial scrub could use some work. This could be a preference but I like my facial scrubs to feel like they're taking a steel wool pad to my face and grinding the dead skin off, and afterwards I get that "fresh air" feel on my face. This doesn't cut it for me. If this was improved I would like this more. 4. The moisturizer. I'll start off with the good, it feels GREAT! It's not oily, it takes only 15-30seconds of rubbing to really get into my skin and just overall great feeling. HOWEVER, who the hell designed that smell. It's like a chemical mint, what in the world, I've never smelled anything like that. Not a fan, I feel us men have to deal with the worst smells; fresh sport, swagger, and tree bark for our options (i elect to pick tree bark). Now chemical mint??? Needs work. 5. No comments on the eye cream, I didn't use it. Probably never will who knows. This is a really solid product, the volume is there for the price, the moisturizer feels great, and the cleanser feels great. If they could fix the intensity of the facial scrub and that moisturizer smell it would be a 5 star for me. If you are the product design team or owner and you're reading this, it's close. Fix the two items I mentioned and you have me as a customer for life. However, I would advise against pushing that price point above $40. I feel the $32-$35 is a sweet spot. Tiege team has lost their minds pushing $45 product for those tubes, don't do that.
