Acids – what are they and why are they good for your skin?

Acids work effectively in different ways to exfoliate, balance, cleanse and enhance your skin's health. They also help your skin to better absorb other active ingredients by removing dead skin cells that otherwise can create a dry barrier, making it difficult for moisturisers or active ingredients to penetrate the skin. Making sure you get the right amount, kind, and percentage of acids in your skincare routine can make a big difference.

I discovered AHA- and BHA Acids over 15 years ago when I was getting a facial from an esthetician. She put acids on my face with a brush and then let it sit for a while. The result was instantly visible. My skin was clearer, more radiant, and I was getting fewer pimples and impurities. Acids have ever since been a part of my skincare- and cleansing routine. When Emma S. launched its first twelve products, it was natural that an enzyme peeling with AHA- and BHA Acids was going to be a part of the selection. Back then in 2010, not many skincare brands had acids in their assortment. It is more common today.

What different types of acids are there within skincare and what do they do?

The most used acids are AHA, BHA, and PHA and they all target the skin in different ways.

  • AHA is a water-soluble acid with smaller molecules that exfoliate dead skin cells and speed up the cell renewal process. They also help your skin maintain and lock in moisture. By removing dead skin cells, your skin will get a healthy glow and dry lines will be reduced.

  • BHA Acid, or Salicylic Acid as it is also known, is a fat-soluble acid that exfoliates the skin while dissolving sebum from blocked pores. It is an acid that works well on oily skin but can also help a surface dry skin to overcome tough and hard blackheads. Salicylic Acid also has a calming effect on the skin.

  • PHA Acid is also a water-soluble exfoliating acid that is gentler than the other two and is great for locking in moisture. PHA Acid has much larger molecules than AHA- and BHA Acids which means that it does not penetrate the skin as deep, thereby working well for sensitive skin.

If you use products containing acids, you should always use a high SPF if you will be out in the sun. Acids, especially AHA-acid, exfoliate your skin causing it to be extra sensitive. It is also important to not use too many acids with excessively high levels of concentration too often because the skin may react negatively. You should completely avoid acids if you have rosacea or very sensitive skin.

Emma S. has now introduced two new products with acids into the assortment. A toner with 2% Salicylic Acid and a foaming cleanser with BHA- and PHA Acids that keep your skin clean, clear, and fresh. If you still have not discovered the amazing effect acids have on the skin – it sure is time to find out.
