Benefits of AHAs

AHAs are well known for their use in cosmetics. They are used to make different skin related cosmetics such as creams, face wash, toners and many more. They are great exfoliators (removes dead cells) and increase blood flow to the skin which in turn helps in:

  • Reducing uneven pigmentation and acne
  • Treating sun damage

Alpha hydroxy acids are also used to treat extremely dry skin when this condition develops in pregnant women. (Please check with your doctor or dermatologist if in case you are pregnant before applying AHAs containing results to avoid reverse results)

How do AHAs work?

The main benefits of AHAs are as below:

  • Exfoliate the skin.
  • Effectively remove the top layer of skin and help new skin to grow.
  • Reduce wrinkles, make skin smoother and can help uneven and pigmented skin become smoother and evener.

It is also believed that alpha hydroxy acids also stimulate the growth of elastin and collagen which give skin its youthful look and elasticity. Elastin and collagen in our skin cells get lost with age and incorporating AHAs into our daily skin care routine can regenerate these compounds in new cells. which get exhausted with age.

Significance of AHAs in Acne Treatment

Acne occurs when the skin produces too much oil which leads to the clogging of the pores. AHAs do not help sebaceous glands to stop producing oil from the skin but it regenerates the top layer of the skin and peels off the dead skin cells and unclog the pores. Once the top dead skin layer peels off, new and clear skin forms.

AHAs work great with the combination of benzoyl peroxide to prevent pimples to form. First, one will feel irritation on a particular spot where AHA has been applied, but it will stop a pimple there to grow.

Guidelines

When you use an AHAs product, your skin becomes more prone to damage from the sun. It is highly recommended to use a high-quality sunscreen to protect your skin from the sun.

Side Effects

If the symptoms continue after you stop using the product for some time, try using a product that contains less of the AHA concentration. In case if it still occurs, contact a dermatologist.

If you have a dark complexion skin, consult your doctor before using an AHA or BHA. People with dark skin are at a higher risk for scarring and pigmentation than those who have pale complexions.
