Antiageing serum or cream advice

Hi 
I would like to thank everyone in advance for their help. I am trying to formulate an antiageing cream for my sister who is close to her sixties and has dry skin with pigmentation. I would like to create a serum with hyaluronic acid and vitamin C combined. But I have read that with these products stability is an issue. And also there is a question of the molecular weight with HA. I can get the HA in liquid form but only with 1% active or 100 active powder in both cases very expensive.  
My question is if I formulate with these two ingredients how do I make sure it has a good shelf life. Or are there any new raw materials that have better efficacy without the stability issues.
Can I use HA in Haircare products??

  • If we are talking about high molecular weight Hyaluronic Acid that is used for thickening purposes you won't be able to dissolve more than 2% and even that would be unpleasant. From the cost-effectiveness point of view, it's better to get the powder.
    Don't expect hyaluronic acid to have any significant effect on the dry skin. It's overpriced and there are plenty of effective humectants for a fraction of a price.
    There are vitamin C derivatives that oxidise less, but in my experience, they all do (at least the ones I tried) and it's a matter of time. If the product is for personal use, you can make small batches of the serum (as simple as LAA, Water, HA) and keep in the fridge. It should be ok for 2-3 weeks. Again, don't expect a drastic effect. I don't want to discourage you from making something yourself but not all actives do work. In most cases it's marketing.

    The best solution for problems you described (ageing skin with pigmentation) is prescription retinoids.
  • Thanks for your reply. You have given me new direction in my thinking and save few dollars along the way. 
  • @raveena, I don't want to discourage you from formulating your own products, but, you would waste a lot of materials and time (years and thousands of dollars) before it will start making any sense. If you want to make a lotion with nice texture and add your favourite fragrance oil to it to gift it to your friends it's one thing (you can totally do it), but if you want to get noticeable results it's easier to buy.

    If you want to go for correction and pigmentation you can use  Niacinamide and N-acetyl glucosamine (NAG) combo. Search it out, not bad combination. There are many humectants on the market which are much cheaper than HA. Nothing really special about HA. Just from my experience, can't speak further, but HA actually works better for people with acne or combo skin, not really dry skin.

     I have read so much about the benefits of the HA about plumping up the skin and add hydration to matured tired skin. Are these claims misleading? I am truly after the raw materials that would freshen up and add glow to tired and matured skin. Any suggestions would be really appreciated.
    And I do want to formulate my own as I love formulating new innovative products.
