Acid 101 - Glycolic, Lactic & Hyaluronic Acid


I'm sure most bloggers or beauty junkies are aware of Acids used in skincare products, they seem to be the very 'it' ingredient at the moment. And for good reason, the results of using them are brilliant. But when I try to preach skincare acids to non bloggers, they look at me like I've gone crazy! So I've put together a little info post on Glycolic, Lactic and Hyaluronic Acids. They're are so many other acids on the market (salicylic, retinols etc) I'll cover some others in another post! Please bare in mind, I am no scientist and this information is found through my own research, because it's something I'm passionate about!

Lactic Acid 


This is the acid that I personally have seen great results by using. Lactic Acid belongs to the Alpha Hydroxy Acid (AHA) family. It is derived from milk and is found naturally in the human body, so it is seen to be a more natural type acid and easily accepted by the skin, so it may be one for people with sensitive skin. It has many skincare skin benefits which include, gentle exfoliation, fading pigmentation, treating and preventing breakouts. It works mainly by breaking down the bonds that hold dead skin cells together which can cause breakouts and dull skin. The concentration of the acid varies the result, but most 'at home treatments' I have come across usually contain a concentration of 5-10%. I love the Bravura Lactic acid* | POST | and it has made a real difference to my skin. I like to apply to a clean face and leave it on for 10 minutes and my skin is instantly softer and brighter looking. Over time I've noticed a difference in the amount of breakouts I've had too. Now, this may sound like a wonder acid but it is to be used with caution. It can irritate the skin, if it is very sensitive! You should also take extra caution to sun exposure, as AHAs make the skin more sensitive. I haven't experienced any adverse reactions but it's something to bare in mind.

Glycolic Acid 


Gycolic Acid is also part of the AHA family but is derived from some fruits. It typically has the same effects as lactic acid but can also be used to treat fine lines and sun damage. It's said to be the most effective AHA because it penetrates the skin deeper. It works as a gentle exfoliator to break down the bonds that hold dead skin cells together. It's also worth noting that these types of exfoliators are said to more effective and more gentle on the skin than manual exfoliators (ones with scrubby particles). In my experience I've had a better experience with Gylcolic acid when the concentration is a lot lower (around 5%) I'm not sure why but some Gylcolic acids have left me with really bad breaks outs that don't seem to go. My favourite low concentration one is the Pixi Glow Tonic | Post | It's gentle enough that it can be used daily and it really brightens my skin, and helps my dehydration lines. That being said I have seen great results from the Bravura Glycolic Acid* | Post | It has a concentration of !0% and can be used once or twice a week. I like to apply this, leave it for 10 minutes and the results are great! My dehydration lines have started to look better since using this and it leaves my skin super soft! Like Lactic Acid, Glyocolic acid comes with the same cautions!

Hyaluronic Acid 


This really isn't as scary as it sounds. Hyaluronic acid is a super hydrating acid that can hold more than triple its weight in water! It's naturally found in the body but it decreases with age. It's the reason why babies have super plump skin! So it's great for ageing, dry or dehydrated shin. Hyaluronic Acid is a 'trendy' ingredient at the moment, but it's not to be over looked! It can be found in many moisturisers and serums.  My current favourite Hyaluronic acid product is The Ordinary Natural Moisturising Factors | POST. This contains a range of ingredients that work on the top layer of the skin to keep it hydrated - which this really does. It leaves my skin so soft and smooth. I can't believe this costs £5, it easily rivals moisturisers with a £30 price tag!

I'm no scientist and I don't know much about skincare ingredients but I've done a lot of research because I find it interesting. I also think it's important to know what ingredients work for your skin and what doesn't. I hope this gave you a bit more insight into some skincare acids.

Do use any of these acids? What are your thoughts?

Until next time...
