I don’t like skincare products that feel sticky, and this serum is very lightweight and absorbs quickly while leaving my skin looking radiant. I like using it at night because I wake up with very soft skin or before makeup. I would recommend it for dehydrated skin. I haven’t experienced any irritation from this product so far.

This serum has become a staple for me! I have rosacea and extremely dry skin, and this left my skin feeling so soft, hydrated and plump without any irritation! I definitely reccomend it!

I've been really impressed with the Dr. Althea Aqua Marine Deep Serum. From the first use, my skin felt noticeably more hydrated and refreshed without feeling heavy or greasy. The texture is lightweight and absorbs quickly, making it easy to incorporate into both my morning and evening skincare routines.I especially appreciate how soothing it feels on days when my skin is looking a little tired or stressed. It leaves my face feeling soft, smooth, and comfortable, with a healthy-looking glow that doesn't appear oily. It also layers well under moisturizer and makeup without pilling.A little goes a long way, and the packaging makes it easy to dispense just the right amount. If you're looking for a serum that provides lasting hydration while helping calm and refresh your skin, this one is definitely worth trying.

I like this but it’s definitely not as good for hydration as I thought

It was for my daughter. She digs it.

For context, my skin is combo, prone to dryness and redness on my cheeks and oily on the t-zone, I am also quite sensitive to strong ingredients.I have experienced no irritation with this serum and it has proven true to its' claims. It is so lightweight yet effective and sinks right in without leaving any residue. Any time I have stepped outside of using this serum in my routine for a few days, I experience irritation, dryness and breakouts, but once I'm back to using it, my skin settles back down to being balanced, clear and smooth. It's proof of how good the product is. Also on a side note, I have repurchased this serum along with the rest of the Aqua line over 3 times.

staple in my skincare routine, love it , repurchased 2 tims thus far, definitely helps with hydration & dry skin if you have issues with that. can be sticky if used with other serums, i think depending on the formula

I love this serum so much!!! Ever since I have found this serum I have not gone back. It feels lightweight and refreshing, it feels great on my skin. It absorbs quickly without leaving any sticky residue, which makes it easy to layer with other skin care products. The texture is watery , which gives an instant cooling and hydrating feel after applying it on to your face. I’ve been using this consistently for a couple months now, I have noticed some changes on my face. I have light, fading acne and this serum has helped fade my acne more, and it has helped brighten some spots on my face. This serum didn’t cause any irritation or breakouts for me, and I have sensitive skin. There isn’t no smell to this product. Overall impression, it’s a nice hydrating serum that works for daily skincare and keeps the skin fresh!

I use this before hyaluronic acid in my skincare routine. It’s very thin and moisturizing. I have middle aged, dry, sensitive skin and this works so well. It’s very affordable too!

This product is absolutely amazing

Delivery was 2 days quicker than expected so top job aust post.The product is lovely, no harsh strong scent.I have incredibly sensitive skin and previously the only brand I could use was a $180 tub of Moisturiser that I didn't dare use on any other part of my body.This product I have used on my face, arms, elbows, neck, bikini area (that gets extremely dry where underwear sits), legs, basically my entire body and within about 20 minutes nothing felt tight or dry, itchy anything just soft supple, smooth beautiful skin and I only used maybe 30 odd drops it goes a long way but if I use it in this way on the daily it will be used up faster.I bought this because of a woman I follow on Facebook and I do not regret it. I will be buying more especially whilst it is on sale.I have 0 complaints and the bottle is so cute, my husband thought it just looked like an old perfume bottle.

This is wonderful. It feels like water gliding on your skin without the greasiness or other types of creams. Love it.

I knew I was going to love this serum the moment I saw it, now I’m only planning on getting the moisturizer from the same line… we’ll always repurchase x

I’ve come to rely on this serum for comfortable hydration on winter skin. I ll be reordering. It’s light yet hydrating . Does smell garlicky or oniony when applied on my skin but not when it comes out of vial. It’s a weird plant smell - this is bamboo water after all- that disappears quickly. I find it does not irritate nor cause beak out . I reorder.

Okay it looks beautiful but also feels super moisturizing on my skin. Dr althea has become my staple because I also use their moisturizer

This is the first Dr. Althea product I have tried. It’s an aquamarine deep serum and it was perfect for hydrating my dry and sensitive skin. I used a dropper full and that seemed to be enough. I used ii in the morning and night for this first impression review and it was very hydrating. At the time of writing this review, the cost is just under 17 dollars which seems like a great price for a Korean serum. I will continue to use it and update this review if necessary. 4.5 stars, rounded up to 5.
