"I’ve been using the Bioactive Renewal Day Serum every morning for the past eight weeks and I’m genuinely happy with the results. I probably didn’t realise how much my skin had changed until I put my before and after photos side by side. My skin looks smoother and more hydrated, particularly around my cheeks and lower face, and I can see some softening of the fine lines around my eyes and mouth. My skin also looks a little plumper and just generally healthier. It hasn’t magically removed my pigmentation or freckles, but I wasn’t expecting it to. For me, the improvement in texture, hydration and fine lines has been the standout. Definitely a serum I’d happily keep using. I received this product from Mukti to review."
"I’ve been really impressed with the Multi Bioactive Renewal Serum. It has a lovely lightweight texture that absorbs quickly without leaving my skin feeling greasy or heavy. After using it consistently, my skin feels noticeably smoother, softer and more hydrated, with a fresher healthier looking glow. It layers well with my other skincare products and works nicely as part of both my morning routine. I haven’t noticed the reduction in fine lines however will continue using it. I received this product from Mukti to review."
"I don’t usually expect to see a big difference from one skincare product, but Mukti Bioactive Renewal Day Serum pleasantly surprised me. After using it every morning for eight weeks, my skin looked brighter and felt smoother. I noticed my skin tone looked more even and the overall skin texture felt smoother and looked more radiant. The serum absorbed quickly and didn’t leave any sticky feeling behind and it layered well with my daily moisturiser and sunscreen. A small amount was enough to cover my face, so I think the bottle will last quite a while. The scent was a little stronger than I’d normally choose, but it disappeared pretty quickly, so it wasn’t an issue for me. I didn’t have any irritation or breakouts, which is always important for me when trying something new. Although I didn’t notice a dramatic change in fine lines, my skin feels more hydrated and looks healthier overall. I’d happily continue using it as part of my daily routine. I received this product from Mukti to review."
"I’ve been using this serum for 8 weeks now and I do like it. My skin feels really nice and soft to the touch after applying. It absorbs well and isn’t sticky. I haven't noticed any major visual differences in my skin's appearance yet, but it’s still a lovely addition to my morning routine!"
"I like how this serum smells good. You know it's not from any artificial ingredients but from the native botanicals, which is assuring. I find my skin looking healthier after using it in the past few weeks. It's also more hydrated and softer. Generally, my skin looks brighter than before. I haven't noticed any obvious improvement to my fine lines around my mouth, as pictured but will continue trying this. It absorbs and layers well, and looking at the results so far, I'm hopeful it'll continue to improve the overall look of my skin. I received this product from Mukti to review."
"This serum has layered really nice with all of the other products, it has a nice scent and my face felt less puffy and felt more bouncy. Gave my face the extra hydration it needed. I received this product from Mukti to review."
"Loved this product. Made my skin feel soooo hydrated, firm and soft. Skin texture has never felt better and it has allowed my make up to sit so nicely. My skin feels brighter & fresher than ever before"
"Hydrating, but no brightening effect unfortunately. Overall hydrated/dewy appearance lasts all day! Did not sit well under my makeup but great if you’re having a make up free day and want to glow!"
"I’ve been using this for years. I love that it absorbs into my skin rather than sitting on top. I think it helps with fine lines. An every day staple for me."
"This day serum is the best on the market . In fact all their products are. I have every single one of their products. My skin used to be dry and dull, but now it’s dewy and glows head to toe. I get lots of compliments on how good my skin looks and that’s with no makeup days . Also when I do wear make up it’s much less than what I use to wear since using Mukti products."
