AHAs / BHAs / PHAs
What It Is

The world of acids can be divided into a few categories, three to be precise: Alpha Hydroxy Acids (AHAs), Beta Hydroxy Acids (BHAs) and the underdog, Polyhydroxy Acids (PHAs). If you're using a skincare acid, it'll fall into one of these three categories.

AHAs

These may ring some bells as you're bound to find an AHA already hiding in your skincare routine. AHAs are chemical exfoliators that can be extremely helpful for oily or blemish-prone skin if used on a regular basis.
The top dogs in this category are Glycolic Acid and Lactic Acid. You can find them mixed in with serums, moisturisers, cleansers and toners, depending on how high of a dosage you want to use (the smaller the percentage, the less potent the formula).

BHAs

Whilst they are also chemical exfoliators, AHAs and BHAs treat different skin problems.
AHAs are ideal for those concerned with ageing skin, whereas BHAs are best for those who are one the oilier side of the skincare spectrum and struggle with acne, blackheads and milia (the little white bumps you sometimes see under the skin).
Whilst AHAs are only water soluble, BHAs are oil soluble, which is why they are ideal for those struggling with an oil-slick T-zone. They can get below the oil that’s clogging up your skin and also have antibacterial and anti-inflammatory properties. So they help spots disappear quicker and calm any redness.
The most popular BHA is Salicylic Acid. It can be found in a range of different formulas targeted at spot treatments.

PHAs

The underdog of the acid trilogy, PHAs don't get the praise they deserve.

"PHAs (AKA Polyhydroxy Acids) are very similar to traditional alpha hydroxy acids, because both work by breaking down the 'glue' that binds dull, dead cells to the surface of the skin." Daniel Isaacs, Scientific Director at Medik8

They're especially beneficial for those who find other acids too strong. 'Even very sensitive skin types can harness the resurfacing powers of PHAs,' says Daniel. 'In clinical studies, they have been proven to be compatible with dry, itchy skin conditions such as eczema and atopic rosacea.'
The most common PHA acids are Gluconolactone, Galactose and Lactobionic - bit of a mouthful to say but well worth looking out for the next time you’re in the market for a new chemical exfoliant.

Hyaluronic Acid
What It Is

Hyaluronic-acid a substance that retains moisture and is capable of binding over one thousand times its weight in water. This substance is naturally found in many areas of the human body, including the skin, eyes, and synovial fluid of the joints.

As we age, the production of key substances in the skin, including hyaluronic acid (along with collagen and elastin) decreases. As a result, our skin loses volume, hydration, and plumpness.

The substance works as a magnet for moisture, helping your cells retain as much of it as possible so that your skin feels and appears hydrated, plump and healthy.

What It Does

Moisturisers and serums are two of the most common form of hyaluronic acid.

  • Moisturisers. Use a moisturiser infused with hyaluronic acid at the time when you’d usually moisturise. Ideally, this would be 2 times a day and always after cleansing, exfoliating, or applying serums.
  • Serums. A hyaluronic acid serum involves a slightly different routine. After cleansing, use a toner on your skin and press a couple of drops of your serum into your face with the palms of your hands. Don’t forget to apply a moisturiser immediately afterward to seal in all that hydration.

This acid also plays well with most other skin actives, making it easy to pair with peels, retinols, vitamins, and other acids.

Benefits

When used in skincare products, including creams and serums, hyaluronic acid gives your complexion a boost by quickly increasing the skin's moisture level. It’s especially useful for reducing the appearance of wrinkles and age lines.
