    SNSで広告を見た時、洗顔後何回も付けると言ってましたが、一回でもペトペトして、過剰に感じる程のテクスチャーでした。ただ、刺激は無く、敏感肌やゆるぎ肌にもむきそうです。私は洗顔後、直ぐに塗布し、しばらく置いてから、さっと洗い流していつものスキンケアをしています。勿体無い感じはしますが、肌の感じは良いです。

    Tried this because of all the advertisements. Does not work for me. In fact, I broke out each time I applied this to my face.

    This is a gem in repairing and nourishing the skin barrier. I started using Demaf skincare a month ago after neglecting my skin for 6 years working from home. I have dry skin and I started noticing wrinkles under my eyes and around my mouth. My skin tone was dull as well. I stumbled upon Demaf's CEO's (Regina) YouTube on skin barrier and she seems really passionate about helping people improve their skin. I ended watching all her master classes about skin on YouTube and decided to try out the Demaf skincare a month ago. I put 6 to 10 layers of this My First Serum, so it soaks deep into my skin. It is so lightweight and my skin feels so hydrated and refreshed. The key for this serum to be effective is layering, so it soaks pass the first layer of the skin. I follow with Demaf EGF peptide ampoule, Panethol, and then Dream Come True mositurizer in the morning and at night. After a month, my skin has dramatically improved. My face has a glow that looks like the Korean glass skin, wrinkles and dark spots are not as noticeable, and skin is smooth and elastic. Friends tell me I look younger and asked what I did to my face. This serum is a must if you want a deep nourishing serum that is effective, and yet inexpensive.

    This is my third bottle using this bubble serum. I have used wipe up toner for long time. This serum is totally different with what I have used before. After using this serum, mu face stays moisturized and looks radiant. I love pumping part since it makes the form well. After pump, mix it in my hand and tap gently on the my face. It feels so good. Highly recommend for one who has sensitive skin.

    I really really really love this serum. Its a very watery serum so I will often use this as a toner step. The pump foams the product so I feel like I have more control and waste much less. The serum is biphase, so you have to shake the bottle to get the hydrating essence and oils to mix. I have balanced leaning oily skin and was very hesitant about the oils. It never made me break out. The oils also didnt feel heavy as if I was putting face oil on. That being said, the oils do make it feel richer and this is a night time only product for me. The hydration and nourishment this provides will plump up the skin and improve the appearance or pores and lines. I also found my skin continued to improve with regular usage. I got the mini and when I first saw it I was a little hesitant at the ml/dollar. However, because I was able to waste much less product a bottle lasted me for almost two months making it good value for the price for me. De:maf was also founded by someone who struggled with acne prone skin so I would imagine all their products are also acne safe.

    I’m truly obsessed with this essence. It’s the only product that has worked for my overly sensitive, dry, rosacea skin. It doesn’t sting and hydrates my skin all day and night. It’s not sticky once absorbed. It doesn’t pill under other products or makeup. No scent. Unlike watery essences, this is a milky emulsion that deposits ultrafine lipids (ceramides, phospholipids, and hydrogenated lecithin). Those droplets settle between corneocytes and locks in the NMF’s water.This dual repair (lipid + humectant) gives a pillowy, super hydrated look and feel. I use it AM and PM. Incredible value for money.

    This serum is so perfect in every way for me. It is very watery and comes out as foam. It’s easy to use it as a toner but also a serum because you can layer it multiple times for deeper hydration. Since using this, my skin looks so hydrated and looks radiant when I use it alone or under makeup. Truly the best serum I have ever used.

    It’s a great product. I use it after my reedleshot. Keep my skin moist and glowing. Unfortunately, Amazon kept on sending me the wrong size. First time was wrong then I got the replacement, still wrong. I ordered one for my sister in the larger size and they still managed to send the wrong size.

    I highly recommend this combination of the First Serum + EGF Peptide Ampoule! I really hope more people try it. I’ve been using it consistently morning and night for about two weeks, and here is my review.My skin type: Combination (dry cheeks, slightly oily T-zone)• How it feels / How I use it:After washing my face, I don’t towel-dry. I apply the First Serum directly onto my damp skin, layering it about three times. No scent. If you keep layering it, you’ll go through even the large size pretty quickly. They say you don’t need to wait for each layer to absorb, so I just apply, apply, apply. After three layers, my skin feels incredibly hydrated and soft. Then I apply a generous amount of the EGF ampoule and massage with my fingertips until it’s fully absorbed. My skin feels deeply moisturized and plumped from within—it’s such a good feeling. I finish with a cream on top.When I wake up in the morning, my skin feels so soft that I don’t even want to wash my face. Even after washing and applying light makeup, my skin feels comfortable and looks radiant. I’m sure the effects will be even better with continued use.— Tips:In the morning, I pour enough First Serum onto three cotton pads, place them on my cheeks and forehead right after washing my face, and then I dry my hair with them on. After letting my skin soak it all in, I lightly apply a cream and then sunscreen—that’s it for morning care. The glow is beautiful, and my skin stays healthy and hydrated all day without any tightness.Overall, I strongly recommend using these two products together. Especially for moms who don’t have the time or energy for long skincare routines, this method is simple and effective without any stress.
