How Long Should Glycolic Acid Be Left on the Skin During a Treatment?

The depth of peel is dependant on the thickness of the skin, whether the skin has been prepaired by medical grade skin care or not.

the end point is dependant on the skin reaction, such as redness, frosting.

That is why all chemical peels should be done by the physician

The duration of application for glycolic peels will vary from patient to patient. After prepping the skin and applying the glycolic acid the practitioner typically observes the skin for certain endpoints - such as fairly uniform redness and the patient’s sensation of tingling. Once those endpoints are met, the peel is neutralized. I usually can leave a peel on for at least 3 minutes and I generally don’t go past 6 minutes. It’s hard to assess your situation but my reaction is that it would not be typical to leave a peel on for 10 seconds.

When performing a peel, the practitioner will be observing your face for signs that the skin is reacting well and sufficiently before neutralizing the peel. I typical leave the peel solution on for 3 minutes to begin with and gradually increase the time of contact of the peel with the skin. The time can vary from patient to patient and is even different in the same patient from day to day.But do consult your dermatologist before your next session.

How long a peel is left on the skin will depend on the product and protocol. More typical is an application of 3-5 minutes. Ten seconds is not wrong but it does sound short.

Each company has a different set of protocols for their product. Moreover, physicians tend to differ whether to hold strictly to time or to see how a patient responds.  The important factor is improvement, and improvement can occur with different philosophies.

Chemical peeling can be confusing.  There is no specific amount of time the chemical should be "left on".  With glycolic acid: once the chemical is applied it will continue to affect the skin until it is removed or diluted (some say neutralized) by applying water or a bicarbonate solution (which fizzes).  The time to neutralize depends on the reaction of the skin.  Some sensitive skin may only take a minute or two where thick oily skin could take 10 or even 15 minutes.  The buffering and concentration of the chemical also play a role.  You need a good aesthetician, hopefully in a physician's office, who knows the product they are using well.  I agree, 10 seconds seems a bit fast.

Glycolic peels must be timed to be safe. The average patient will need about 2 minutes before neutralizing with water after having 70% glycolic acid applied to the skin.

When I do a glycolic acid peel, my end point is entirely based on the visual changes I see in the skin, not the time the acid is in contact with the skin. There are too many variables such as skin type, pre-peel preparation, prior use of tretinoin cream, etc. to depend simply on how long the acid is on the skin.
