@SilleeMee I am not prone to acne but I don't use coconut oil as it does clog pores on the face. I don't use retinoids either. I do want to try her Vit C as I am developing an age spot on the side of my face. I am lucky that I have normal skin & so far I have what works for me. Thankyou for the ingred's! Can you or @Shanus or others reco. something else I can use just on that spot or should I go ahead & get the Vit.C???

If you don't want to go with hydroquinone (HQ), which I can understand why, then I recommend a serum with the vitamin C derivative THD ascorbate. That is an oil form, highly stable VC which works at very low concentrations and absorbs into the skin rather well. But be prepared to spend more for most serums containing it because it is not a cheap ingredient. At only 10% concentration, it has been shown to eliminate age spots in 16 weeks. I know this is true because I had the start of a brown spot and now it's gone. I use my own THD formulation of 10% strength. My skin has responded well to that as seen with no hyperpig and skin texture is smooth and firm. THD is a relatively new kid on the block for VC products and people are liking it a lot. Several brands make a serum with it. You have to look at the ingredients to find one....I know, PITA!
The following I took from LotionCrafter dot com. It's somewhat technical but it states some intriguing info:
"Properties (THD)
- At 0.1% reduces melanin synthesis by 80%
- At 10% eliminated age spots in 16 weeks
- At 3% in vivo reduces Delta-L value by 15% vs. placebo (22 people), a way to measure whitening effect
- At 0.1% in vitro increases collagen by 50%
- Tested at 10% in vivo to treat acne with 80% of patients (12 people) satisfied with results
- Increases collagen synthesis at least twice as much as ascorbic acid
- Inhibits MMP-2 and MMP-9 over e time better than ascorbic acid
- decreased 80-OHdG induced by UV-A
- decreased p53 expression induced by UV-B
- Protects the cells against UV-B better than other esters of Vitamin C
- Works synergistically with Thiotaine as both penetrate the cells for anti-oxidant activity"
When it comes to VC serums, most contain L-ascorbate and the cost of some of those serums can be astronomical....ridiculous, I'd say. L-ascorbate is a very inexpensive ingredient but where the cost comes into play is everything else in those products used to keep the VC stable, including the container it comes in. All of these things add to cost of a serum to keep it stable and preserved. Most of the time you're paying for stabilizers and preservatives (unfortunate yet necessary) in any one product so what you get is effective and not inactive.
