What are Alpha Hydroxy Acids (AHA’s)?

So, what are Alpha Hydroxy Acids (AHA’s)?

The AHA family of acids are derived from natural sources such as fruit, milk or sugar.

Generally speaking, the benefits of AHAs on the skin include exfoliation, brightening, smoothing, anti-aging, and acne prevention.

Two of the most commonly used AHAs in skincare, however, are glycolic acid that is derived from sugar and lactic acid which is made from milk.

The former is unique in that the molecules of glycolic acid are smaller than those found in other AHAs which allows it to penetrate deeper into the skin providing its benefits more effectively and to more layers of the skin.

Lactic acid, on the other hand, offers the same benefits of other AHAs but as a non-friction exfoliant that breaks down and dissolves dead skin cells without causing skin irritation, it is suitable for use on sensitive skin.

AHAs are water soluble so only work on the skin’s surface.  They are generally preferred for normal to dry, sun-damaged skin, due to their ability to enhance natural moisturising factors within skin.  AHA’s have also been proven to be effective in reducing the visible signs of sun damage, including crepey skin and wrinkles.

Can You Combine AHA and BHA?

Using an AHA exfoliant, known as chemical exfoliation, rather than the ‘mechanical’ action of a scrub is not as complicated or scary as it might seem.

If you’re choosing well formulated, gentle exfoliants, there really isn’t a downside.  However it is important to monitor how your skin responds and adjust usage if needed.  Do not keep doing the same thing if it doesn’t work.

How often should I use an AHA

Should you apply an AHA time twice per day? Probably not.  I would say no.

Most people do not need that level of exfoliation but experiment to see which combination and frequency of application work best for you.

Alternate exfoliants and how often to exfoliate

• Most people can exfoliate once a day, in the morning or evening based on personal preference.
• If you want to alternate an AHA and BHA, simply decide which exfoliant to use at the beginning of each week and then alternate day by day. You can also use one for a week, then switch to the other the following week.
• Another option is to apply one type of exfoliant in the morning and another at night. This can be a great approach for breakout-prone skin showing signs of sun damage.
• You also can experiment by alternating different strengths of an AHA or BHA, or both!
• Once or twice per week, rotate into your routine a higher-strength specialised AHA to give yourself an ‘at-home peel’ experience that delivers more dramatic results.

Ultimately, there’s no single best way to use AHA exfoliants.  It is all about experimenting to find out what works best for you and then adjusting based on the changing needs of your skin.

Lots of love

This is all said with love, I know many people have different opinions and that is absolutely fine.  The biggest piece of advice I always say is:

‘Listen to your skin!!’

If it doesn’t feel right, it probably isn’t.  These should not cause any damage to your skin, if used correctly for YOUR skin!

Any questions, just ask…

Much love.
