Docore Triple Core Serum is a multi-functional serum that contains the wrinkle-improving and whitening active ingredient "niacinamide," the skin-irritation prevention ingredient "dipotassium glycyrrhizinate," and other medicinal active ingredients. It spreads easily, has a refreshing texture, and is non-sticky yet deeply moisturizing, which I really like. I think it's also gentle on sensitive skin.
[DOCORE] Triple Core Serum Trial Size Points: Effective ingredients address adult skin problems; Suitable for the entire face!スキンケア用品 スキンケア好きです。 English: Great for spot application on problem areas ♀◎Glides on smoothly and leaves skin smooth without stickinessIt's great that it comes in a size that allows you to try it out to see if it suits your skin °°°°°°This time we'll be introducing a medicated serum from DOCORE. It takes a triple approach to addressing adult skin problems that many people struggle with: wrinkles, whitening, and rough skin. This serum is formulated with both niacinamide and dipotassium glycyrrhizinate, which are known to be effective against skin problems. It can be used on the entire face, but it can also be used on problem areas as an added bonus to your regular skincare routine ♀◎It's packed with plant-derived ingredients so it's gentle on the skin. It also gently cares for skin that tends to become unstable when the seasons change. The moist, milky white milk cream blends smoothly into the skin without feeling sticky. I used it in my nighttime skincare routine, and I think some people worry about whether skincare products that make skin glow and firm will suit their skin, but I'm really glad that this comes in a size that allows you to try it out! It's currently selling like hot cakes at drugstores, and I've included a photo of the packaging, so I hope it helps you with your shopping. It's a recommended serum that leaves skin moisturized and smooth, and is suitable for sensitive skin. Thank you so much to DOCORE for this wonderful product! °°°°°° #docore #docorejp #docore #docoretriplecoreserum #medicatedserum #serum #wrinkleserum #niacinamide #dipotassiumglycyrrhizinate #wrinkles #whitening #skincare #beauty tics #donated
It has a refreshing, moisturizing texture like a lotion. It spreads easily, so it doesn't burden the skin. I have sensitive skin, so I can use it with confidence. It's only been three days since I started using it, and I feel like the wrinkles around my eyes that appear when I smile are less noticeable! The triple approach to adult skin concerns is what caught my attention lol. It contains two medicated active ingredients: niacinamide (wrinkle improvement, whitening), dipotassium glycyrrhizinate (anti-inflammatory), our proprietary ingredient DcI flambangenol (moisturizing ingredient), pineapple ceramide (moisturizing ingredient), and royal jelly fermented extract (moisturizing ingredient). It's gentle on sensitive skin, leaving it smooth and clear. It's free of eight ingredients: fragrance, silicone, synthetic colorants, mineral oil, alcohol, parabens, petroleum-based surfactants, and UV absorbers.
I received the #DOCORE Triple Core Serum from a campaign by @docore_jp. As I'm slowly approaching the latter half of my 20s, I'm starting to notice more and more areas of concern. >< So, I decided to give it a try, as it promises gentle anti-aging care, including wrinkle reduction, whitening, and skin roughness prevention. The serum spreads easily and is very easy to apply! It moisturizes well, but isn't sticky, so I recommend it for the summer. Also, although it's not directly related to the product, I was very happy to see that each one was individually packaged, so it arrived in such a cute finish.
