Murmura Encyclopedia

In pursuit of the truth behind what is in our skincare products, Murmura has debunked cosmetic ingredients and treatments. Providing all of the information you need to make informed decisions when choosing a product that’s right for your skin.



What are they?

Alpha Hydroxy Acids are chemical compounds derived synthetically and from various plants, fruit and milk.

The most common AHAs found in our skincare products are lactic, citric and glycolic acids.

Lactic Acid is derived from milk and retains moisture in the skin and addresses any redness.

Citric Acid is naturally extracted from citrus fruits and is a great anti-oxidant that also helps to boost your skins collagen production.

Glycolic Acid is derived naturally from sugarcane and has a very small molecule size, allowing it to penetrate the skin deeper for repair. This acid smooths fine lines and wrinkles and absorbs any excess surface oil on the skin.

What are they used for?

AHAs have humectant properties that attract and retain moisture in your skins new cells.

They are chemical exfoliants suited to people with dry or sensitive skin, as they help to gently remove any dead skin cells without the use of harsh scrubbing that can harm your new skins surface.

To stimulate skin renewal


AHAs can reduce fine lines, acne scars and dark spots generating a smoother skin texture. Glycolic acid is a hero ingredient for oily skin, reducing excessive oil and unclogging pores that can cause breakouts. 

AHAs can cause increased sensitivity to the sun (photosensitivity), hence why these should be used in low concentrations to begin with and always use sun protection during the day.

Found in?

AHAs can be found in face washes, masks, serums and moisturisers; though at Murmura we’ve found they work best in serums, giving them longer time to penetrate the skin cells.

For your daily dose of AHAs try some of the following we’ve chosen for you…

What are they?

Ampoules are a super booster for your skin and are packed with high concentrations of active ingredients such as pure vitamins. They are great for a pick-me-up in times of dullness, breakouts, irritation and inflammation. Ampoules commonly come in small bottles with a glass dropper as you only need a few drops per use.

How Should I Use Them?

Though they are power drops, ampoules should complement your skincare regime, rather than replace it. Best applied after your toner, make sure to follow-up with a moisturiser to lock-in all of those active ingredients.  Apply your ampoule once or twice a week to achieve a skin-boosting effect.

For an intense skin workout, leading dermatologists advise to exfoliate before applying an ampoule to get it working on those new skin cells.

Ampoules are free from preservatives or chemicals so check the ampoule label for this symbol that will tell you how many months your ampoule will last, once you’ve opened it.   

Ampoule vs. Serum

The key difference between an ampoule and a serum is the size (molecular) and amount of the active ingredients. Ampoules contain far smaller molecules of the active ingredient than a serum, making it powerful and concentrated.

Found in?

Look out for the main active ingredient in the ampoule’s composition – this can vary and is the dominating ingredient. Missha’s leading Time Revolution Night Repair Science Activator Ampoule has active ingredient Bifida Ferment Lysate, a probiotic that improves skins hydration and barrier to the elements.
