More Effective than Dermalogica Circular Hydration Serum!

I have dry, dehydrated acne-prone skin. I’m diabetic and that’s affected my skin a lot. I have highly sensitive and reactive skin as well due to my allergies. For hydration, I’ve used tatcha’s water cream, Peter Thomas Roth water drench, Dr. Jart Ceramidin and LPR Cicaplast together, Dr. Jart and LPR plus Dermalogica Circular Hydration Serum TO NO AVAIL. My face would still produce oil, not because I have combination skin, but because it’s still dehydrated. I’ve also used Cerave’s HA, Glossier’s HA, Fresh Rose & HA, Glow Recipe, Belif, Paula’s Choice—in short, I tried whatever I thought could help me nourish my skin. When I went to the dermatologist, she suggested Dermalogica. The circular hydration serum was $65 for the bottle alone. It was okay, but it felt like it took forever to see any results. To be honest, I didn’t have much expectations for this serum since I’ve tried so many. But much to my surprise, consistent use did show its effects! I waited a few weeks to really see its benefits. I could see that my face is producing less oil as a reaction to it becoming less dehydrated! It’s very light and absorbs very well! The amount you get is also a lot! No scent, which I love! I’m on tretinoin at the moment and I don’t turn red! I put this on, wait half an hour, tret and moisturizer. I think I finally found my HG serum!!!

Perfect serum for oily skin

If your skin is oily, dehydrated and sensitive - this is the serum for you. I've been using it day and night religiously, and the texture's amazing, my skin feels so soft and healthy! I'm in my twenties, I suffer from skin that's prone to clogging like crazy so i fell in love with it straight away!

Very pleased customer

Now this is a clean formula! Very light consistency, easy to use dropper, easily absorbed, highly hydrating.. i’ve even used it in my home micro-needling sessions .. went great. Probably the best Hyaluronic acid serum i’ve used .. no sticky feeling afterwards and the package is so adorable 🥰

Nice but there is better for moisturizing

Size and packaging is very good, it last for long time. Gentle and Good if your concern is moisturizing and suitable for my sensitive skin. I use it daily. For me, there are better options than it for moisturizing but if I couldn’t find others, i will buy again.

Love it

Great little serum. I have extremely dry skin and live in a dry climate so I layer several serums before I apply a cream. This one is nice, I would recommend it.

Hydrating and lightweight! I’ve been using ISNtree Ultra-Low Molecular Hyaluronic Acid Serum daily, and it’s been great for adding moisture without feeling sticky. It layers well under moisturizer and makeup, and my skin feels plumper and smoother. Really like how gentle it feels — no irritation. Great option if you want deep hydration that absorbs fast!
