Treatments (Face) -Deciem -The Ordinary Vitamin C Suspension 23% + HA Spheres 2%

on 6/19/2018 8:13:00 PM


I read a lot of reviews before trying this serum so I knew what I was getting into. Frankly I was shopping for the price, because my other vit c serum is $20 and I repurchase every few months, I’m too cheap for that. This serum is a bit different than most I have tried. It goes on gritty, but somehow also greasy at the same time. It definitely stung my skin and even after a week of daily application still tingles when I apply it. To help with the grittiness I apply this after splashing water on my face. It seems to break down the grit and helps with the stinging as well.

Treatments (Face) -Deciem -NIOD Multi-Molecular Hyaluronic Complex


I loved The Ordinary's Hyaluronic Acid, so I decided to upgrade when I finished a bottle. In terms or effects, I find they are pretty much the same. For texture, niod's is lighter and basically like a water.

If you love TO's hyaluronic acid, I would definitely recommend this product instead since it's more value for money. Yes this is far more expensive, but because niod's formula is watery and not thick, this one bottle can definitely last you for a lot longer. I've been using this product for about 10 months now and I've used up about 80% of the bottle. I find TO's can only last me 3 months max, both with 2 drops of almost daily use.

I have oily, acne prone and sometimes dehydrated skin. I find it's a great way of adding moisture without the added heaviness that you find from traditional moisturising creams or oils. I loved using hyaluronic acid when I was living in dry London, especially in the winter. Sinks in quickly, relieves dry spots and that tight skin feeling. My skin feels more relaxed, if that makes sense?

I've now moved from London to a more tropical country so I find I have no use for this anymore since I don't no longer get dry patches. I still use it, but I find now it doesn't do much. I would still very much recommend this for anyone suffering from dryness or dehydration!

Treatments (Face) -Deciem -The Ordinary Alpha Lipoic Acid Serum

on 6/18/2018 12:52:00 PM


I really love this stuff! I only use 3 drops 3 nights a week. I will NEVER stop using it. I feel like it improves basically everything (skin texture, tone, moisture, elasticity, even redness etc).

I have sensitive acne prone skin and have never had any problems with it except for maybe some slight stinging around my nose (and this seems to be only when I use it with certain products). I like to think it's because I follow the directions, but who knows? Reactions can vary even in people with sensitive skin.

For the best results use it EXACTLY according to the directions. You aren't supposed to use it with any acids and you're only supposed to use it sparingly (like 3 nights a week). More is definitely NOT better with this product.

Treatments (Face) -Deciem -Resveratrol 3% + Ferulic Acid 3%

on 6/18/2018 12:40:00 PM


I've been using this for a couple months. I think it's really improved my skin texture and it seems to combat discoloration, but I also started using the O's ALA treatment a couple weeks before this one (and I know for sure that one helps skin texture and overall appearance even more), so I can't say for sure how much improvement is due solely to the resveratrol.

The main thing this stuff helps me with is acne. It DEFINITELY helps keep my skin clear. I looked up resveratrol after I noticed this effect and what do you know?! It's actually already been proven as an effective acne treatment in studies.

This formulation is also perfect for my skin because it doesn't break me out (nearly everything "anti aging" does). All it has is that propandiol stuff, which feels like oil (at first) but is actually some kind of chemical humectant (I just know that it's non clogging and considered safe). Once it dries it's not oily or shiny. Haven't had any problems with it under makeup or spf (which surprised me considering how it felt the first time I used it).

The only thing that sucks about this stuff is it can be irritating (it's usually only used in 1% concentrations in most products from what I've read!). I have sensitive skin and it BURNED all day the first time I used it! Made my skin all red too. I had to cut down to using it only once every other night and only 2 drops at a time but after a while I was able to work my way up to using it every day and night. It can still make my skin a little reddish though, depending on other things I've used. If you have sensitive skin to be cautious.

I wish they sold it in a slightly lower concentration but you can't have everything, I guess. At least it's only about $8.

Treatments (Face) -Deciem -The Ordinary Vitamin C Suspension 30 in Silicone


Nice affordable Vitamin C product! After my unpleasant experience with The Ordinary's 23% Vitamin C suspension, I was pretty reluctant to try this one but I'm glad I did! While I can't say I like it as much as a water based Vitamin C serum like Timeless, I had a much MUCH better time using this serum than I did the 23% suspension. Whatever they did with this new silicone formulation went a long way to fixing all of the terrible texture issues the other product has. The product isn't noticeably gritty, doesn't feel as greasy, is easier to spread and soaks in much more quickly than the non-silicone formula. It leaves the nice semi-matte finish I expect from silicone products which means unlike with the other product, I can actually use it as a part of an AM skincare routine. It works great on days when I'm wearing face makeup and on the days I'm going bare. I also found that despite having a stronger concentration that the other L-AA serum from this brand, there was noticeably less stinging. It costs a $1 more than the other serum, but that's a small price to pay for the much nicer formula.

Obviously this product has silicone, so it may cause problems for people with silicone sensitivities. My skin doesn't mind them at all so I consider the presence of silicone in this formula to be a pro and not a con. If your skin can be hinky about silicone products, proceed with caution or skip this product all together.

The only thing I don't like about this product is that it takes a fair amount to cover my face so I'm going through a 1 oz tube much faster than I would a 1oz bottle of a water based serum. That's not a huge deal given the price tag, but it does mean that the value difference between the $6.80 serum from The Ordinary and the $24.95 Timeless serum is not quite as great as it seems at first glance. The value still probably works out in favor of the Ordinary but not by much.
