Great facial wipes
Size: 1 Count (Pack of 25)
Love these facial wipes! I use the facial cleanser soap in the mornings so these are great getting makeup off before bed.

Easy, Gentle and Convenient
Size: 1 Count (Pack of 25)
These wipes are super convenient and easy to use. On days when I am exhausted and just want to crawl into bed without doing a full skincare routine, these are what I reach for. They remove makeup, sunscreen and dirt well without leaving my skin feeling tight or dry. I really like that they contain ceramides, which helps keep my skin feeling hydrated and balanced. Perfect for those nights you are just tired or want a quick cleansing after working out. They also don’t have a scent which is a plus for me.

Removes makeup quickly and conveniently without having to wash your face.
Size: 1 Count (Pack of 25)
First a little about me ... I am a 72 year old woman and I don't wear a lot of makeup. I did back in the 60's and 70's when Twiggy was a fashion icon, hot pants, white boots and London makeup was all the rage. Black and white cat eye eyeliner, long thick lashes and pale lip colors!
I only wear makeup now when going out ... none at home. Covid also put a stop to daily makeup ... why wear makeup it you can't see your face!lol I like a natural look for my age. I wear a light dusting of Laura Geller's baked powder foundation or her liquid foundation. Starting with a primer, then foundation, some blush, and a natural colored lip gloss ... but no eye makeup. I am so envious 💚 of those who can wear the beautiful colored eye shadows, liners and long thick lashes!!! I unfortunately have had fibromyalgia for many years and it causes extreme dry eyes along with the medication I take for it. Any eye makeup is a waste of time for me as I will look like a raccoon 🦝 by the end of the day from rubbing my dry eyes!lol
I was looking for a quick way to remove my makeup without soap and water. I live in Colorado and my skin is dry. Washing my face more than twice a day with soap & water drys my skin out. So I saw this and decided to give it a try.
At first I wasn't sure if there was anything on the cloth when I pulled it from it's holder, but evidently there was because it removed all my makeup very easily with just one cloth. I did not have to apply a lot of pressure, just wiped my face softy all over. It didn't seem to dry out my skin on my face or leave a greasy feel behind either. My face even felt less dry when I woke up in the morning.
I would imagine depending on how much makeup you wear or what kind, may affect how many wipes you would need. I can see it being very useful for getting rid of eye makeup, but it does say if you get it in your eyes to rinse your eyes thoroughly with water.
For me it is a good buy so far. I will update as I continue using it and how my skin feels. 5 out of 5
🤩🤩🤩🤩🤩
UPDATE: I used this to remove my oil based face paint that I used for my halloween makeup this year (I was a scarecrow) and it came off very nicely. I did use 2 cloths though just to make sure I left no paint residue behind.

Great for Recovery Nights, Unscented and Budget Friendly
At 52 with combination skin, this cream is exactly what I need for deeper hydration, but not every day. It is rich and nourishing, so I use it strategically, mainly on recovery nights or when my skin needs extra support.
It works especially well after retinol or exfoliation nights, helping to restore moisture and support the skin barrier. By morning, my skin feels soft, smooth, and well hydrated without irritation.
Because it is a thicker cream, I prefer to use it once or a few times a week rather than daily so it does not feel too heavy on combination skin. Used this way, it performs very well.
I also appreciate that Good Molecules products are unscented and very affordable, which makes it easy to build a routine that actually works without overspending.
Great option if you want a richer moisturizer for targeted hydration and barrier repair.

Great value moisturizer for sensitive skin
As someone with rosacea and easily irritated, sensitive skin, I’m always nervous trying new skincare. If you’re in the same boat, this is absolutely the moisturizer to look into.
This formula is incredibly light but still genuinely hydrating. It doesn’t feel heavy, greasy, or suffocating. It absorbs beautifully and leaves my skin calm and comfortable instead of red or burning. It gives the prettiest soft, dewy glow without looking shiny.
One of my favorite things? It layers perfectly under makeup. My foundation doesn’t slide around or separate - it stays put while still looking fresh and radiant. It’s that ideal balance of hydrated but not slick.
I also love that it comes in a tube instead of a jar. No dipping fingers into a tub (huge plus for sensitive, reactive skin). And you truly only need a small amount - a little goes a long way
