What The Power Up Is
The Power Up Silk Concentrate is our bestselling product, designed to prove the power of silk in just 1-2 drops.
It is not a serum in the conventional sense; it is a potent, highly concentrated silk elixir designed to be added to whatever you already use. Moisturiser, serum, face oil, SPF, foundation: 1–2 drops mixed into any leave-on product will dramatically enhance the health and appearance of your skin.
“I wanted people to really experience the potency of silk and how transformative it is for skin. I wondered if we could simply ‘add silk’ to any product. This is how the Power Up was born and it is clinically proven to deliver significant results.”

How
Formulation Science
Power Up contains silk of different molecular weights; these mean enhanced efficacy for the skin.
SF-VII® has been proven in in-vitro skin cell testing to significantly stimulate the skin’s own production of keratinocyte and fibroblast cells, leading to increased collagen synthesis.
In addition to the silk, we use the clinically proven benefits of hyalonuric acid, niacinamide, ceramides and cholesterol to provide a comprehensive and evidenced solution for skin barrier support.
The Power Up has been formulated to be free of all oil and fragrance in order to be as versatile as possible.
Why
Formulation Insight by Founder
“I wanted people to really experience the potency of silk, and experience what a significant difference it makes to their skin. The Power Up was our third product to launch, and people were already witnessing the difference the Silk Cream Cleanser and Silk Face Oil were making, but I wondered if we could ‘just add Silk’ to any leave-on product. This is how the Power Up was born. It is a bestseller and delivers incredible results and we love hearing how people are customising it to fit into their skincare routines - from adding it to serums, moisturisers and foundations.”

Power Up Silk Concentrate is the Elixir of the Gods....not only does it give visible results but you can add it into your existing skincare, be it an SPF for the day or your favourite rich night cream before bed.
So, imagine my double delight when it arrived this morning and even the unboxing process was a wonder, complete with personal note from the brand....online shopping is never going to be the same again esp with those brands that don't love their customers as much as This is Silk ❤️
I have sensitive skin and have recently cut my skincare down to the three This Is Silk products plus an SPF and my skin has been incredible! The power up silk concentrate is especially nourishing. These are all new staples in my every day skincare routine 🖤
This was a delightful serum to use and I genuinely could feel the softness and difference that came after a week or two of using it. You only need a small amount for it to be effective. Would definitely recommend if you are looking for a little luxury but also an effective formula - I found I didn't need to wear much makeup. Only a little blusher and eye makeup and I was good to go.
I’ve just finished trailing the Power Up Silk Concentrate for 4 weeks and it is has been great! My skin is so soft and it’s helped to clear up my dermatitis on my lip which I’m so happy about. It is a little pricey but worth it for the results so far.
I bought this product back in August, and I’m so happy with it. I use great skincare products, but adding 1 to 2 drops of this magic potion - makes my skin feel softer and smoother. I’ve been adding it daily to my foundation or SPF. Last night I added it to my night time routine. A lovely product which I’ll purchase again. A little goes a long way.
I love this product. I feel it keeps my skin looking great
There is a bit of magic contained in Power Up Silk Concentrate. Skin appears to say thank you and there is something comforting about the ritual of adding a couple of precious drops to moisturiser each evening.
It makes my skin glow
I have been using the Power Up for ever , I think since its inception. It really was my secret weapon to keeping my skin healthy, and helping my normal moisturiser keeping my skin hydrated. I have serious health issues am on a cocktail of treatment that is frankly toxic and my skin and hair don’t thank me for it. BUT this company has been my saviour. This little bottle is small but it packs a mighty punch. You might think you don’t get much but you hardly use it and it makes so so much care of your skin. I’m sorry but this is amazing , the staff are amazing if you ask questions. It takes a lot for me to write reviews but i have had a lot of people comment on my skin and how well I look despite being so ill so I have to give credit where it’s due 😁🫶
I was rather skeptical about this product but having used twice daily for 3 weeks and i can see a difference in my skin. I particularly love that i can add this to my favourite products so i don't need to change all my products to use this new one.
I was gifted the Silk serum and have used it daily in my moisturizer.
Firstly I enjoyed the process of adding a few drops into my daily moisturiser. I prefer this to a layer of serum, waiting for it to dry down, apply another layer wait to dry etc. but the noticeable improvement in my skins hydration level is the reason I love this.
I’ve noticed my skin being far more juicy, it’s not tight, fine lines in my eye area have reduced and overall my skin just doesn’t need concealing. This little bottle is incredible for my perimenopausal skin, definitely want to always have this in my routine.
So much silky power in two little drops and leaves skin feeling baby soft
I bought this as a Birthday present for a very good friend. She has told me I must buy one. Beautifully packaged, she said it keeps her face cool and helps her sleep so much better. She was thrilled!
I really liked this product. Used it at night and definitely noticed a skin smoothing glow from it.
I think this a great product. I like that I can just add it to my normal routine, and it really helps my parched skin look, and feel more healthy and hydrated.
I have been using this product for several weeks, it was gifted and I wanted to use it thoroughly before reviewing it..
My skin is going through menopausal symptoms and is definitely duller and drier than normal.
This serum has given my skin a silky healthy glow.
I’ve used a few drops of it into my moisturiser day and night and it’s given my skin the boost which was needed.
I will continue using it as it’s worked wonders for me.
I have been using this product for several weeks now and can honestly say it really does give your skin a silky glow. A couple of drops into your regular moisturizer or night cream is all that’s needed and it glides beautifully on your skin. I wanted to try this product being post menopause, as my skin is somewhat less hydrated these days and a little dull in appearance. A few people have commented on my skin since using this which is always nice to hear. Highly recommend this product
How can such a small bottle bring just joy!!! This oil is just brilliant. Small enough to carry anywhere and it adds much needed grease free oil to your regular moisturiser and leaves your skin glowing. As someone going through menopause and with dry, aging skin, it's wonderful!
I really enjoyed using this product and found it very hydrating. Personally I think a prefer a separate serum to one you mix with a moisturizer but I did feel like my skin was smoother and more hydrated when using this. It is quite expensive so I’m not sure I’d use it permanently but would be nice as a treat/ gift
I really like this, my makeup goes on so well on top of it and it just helps give me a brightness to my skin that I don't usually get. It is pricy though, I think it would be worth trying a sample of it first to see if it works for you.
I was sceptical at first but after ysing this product for 4/5 weeks my rosacea dramatically improved! My akin was soft and hydrated and i really enjoyed adding it to my serums, it felt like a treat - love it!
It’s absorbs beautifully leaving an improved softness
This is a really nice product. Just a couple of drops in my serum before bed - it’s so easy and it will last a long time despite the little bottle. My skin feels smooth and clear - a bit like the effects of retinol but without the irritation. I’ve been using for 4 weeks and love the results - thank you
Lovely little product, felt like silk going on my skin and love the fact that you can mix it in with your usual moisturiser.
I did feel however that it didn’t last that long (4 weeks for me using twice a day) so a little bit pricey for me unfortunately!
I have been using this product for 4 weeks now and I have really been enjoying it. It has left my skin feeling smooth, silky and really comfortable. I definitely think the overall texture of my skin has improved.
The product feels luxurious and I have tried it added to different parts of my routine (moisturiser, serum, SPF, foundation) and it’s worked well in all of them.
A little goes a long way and I think this bottle will last me a really long time.
Love this product, have been using for 4 weeks. It feels like silk in your hands and makes your skin feel so smooth, hydrated and supple.
I didn’t think I could notice a big difference in the appearance of my skin but when I looked at before and after photos my skin looked clearer, dewy and fresher. Lines looked softer. Definitely keeping in my daily routine.
I have been using this product for 4 weeks now and my skin feels so soft and smooth. My hormonal acnes has improved. The product feels luxurious when added to a basic moisturiser and makes my skin feel lovely. I haven't noticed a massive change in the appearance of fine lines but do believe the condition of my skin has improved overall.
I have used this product for 4 weeks now and have seen such an improvement to my skin. My dry patches have disappeared and the fine lines around my eyes and forehead look so much better. I will definitely continue to use this product.
This is a fabulous texture - it feels thick but once it was on my skin it creates a really light, smooth surface. Thankfully only a little is needed each day!
