Yesterday, we discuss about the different types of peels. I would like to go deeper to let you know that not all peels are similar in strength.
Our skin has a natural moisturizing factor of around ph5.6. This refers to the alkaline or acidity balance, with ph 0 - 14. 0 being most acidic and 14 being most alkaline. Naturally, 7 is the neutral point. as you now can see, our skin is slightly acidic. In order for the skin to achieve a peel, the ph has to be below ph3.
Daily skin care items like cleansers, toners, moisturizers and serums that are AHA based usually has a ph of ph3.5. The strength that beauticians are allow to handle is from ph2.2 to ph3.5 and are usually buffered. This means only the superficial layer of dead skin cells are being peeled. Free acids and anything below ph2.2 can only be handled by Dermatologist.
Another factor that affect the peel is the percentage of acid in the solution itself. Again for the daily care product, it usually contains around 8% of acid. For Beauty Therapist, they will use peel from lightest 20% for the beginner clients and will slowly increase its strength as treatment progresses. Because the acids are buffered, they can use up to a maximum of 50% for stubborn acne scars and pigmentation.
Other factors that the beautician should consider before deciding on which peel is the client's skin type, activity level, diet, medical history, etc. With so much factor to consider, it is best to leave the chemical peeling to the professionals then to try it at home. You may just end up with more scarring and pigmentation on the long run. I'll explain this on my next post. See you
