Good moisturizer, not too oily.
I often times use this in the morning before starting my day and it tends to really keep it moisturized for at least 4-5 hours. This is someone who has really dry skin and it constantly always having to remoisturize throughout the day. Nonetheless, I would still keep up water intake and try not to touch your face too much after applying. Quality is great and it has a natural smell that is not overpowering. Would def recommend.

Soothing
Feels good on, no major difference on the dry/flaky skin above eyelid, so time to see a dermatologist.

So far so good
I’ve been using the Eczema Honey Nourishing Face Serum, and overall I like it. It feels rich and soothing without irritating my sensitive skin. I’ve definitely noticed my face feels more hydrated and calm — but it’s still early to tell if it’s reducing eczema flare‑ups long-term.

Fast results for a very reasonable price.
I saw very fast results on the sun damaged skin on the tops of my thighs (I’m 62 and scorched myself at 16-17). Softer smoother skin on the backs of my arms and my crepey forearms.

I’m absolutely loving this soap! The bars are 2.82 ounce each and 2 come in an order. They are the perfect size and have really worked wonders on my skin. After just a few weeks of use, my complexion looks noticeably brighter and more radiant. The soap has helped fade dark spots and even out my skin tone, leaving me with a smooth and glowing look. I appreciate that it’s SLS-free, paraben-free, and dermatologist-tested — it feels gentle on my skin but still effective. My skin doesn’t feel dry or stripped, just refreshed and rejuvenated. The soap lathers really well, and the scent is light and pleasant. Good thing 2 comes in a pack so I never have to worry about running out. If you’re looking for a way to brighten your skin, fade dark spots, or even out your tone, this soap is a must-try. It’s truly a 5-star product for glowing, healthy skin.
