How to use AHAs in your routine, step by step
Introduce AHAs slowly and it tends to behave. Below is the ramp, the application order and what to do if skin protests.
How to apply it
Typical strength is 5–10% for home use. Use it evening.
A four-week ramp
Start one night per week, then up to two.
What it should feel like
Typical sensation: light tingle for a minute; stinging that lingers is too strong. Timeline for visible results: two to four weeks for glow, ten weeks for texture.
Night use, SPF mandatory.
Troubleshooting
Stinging or flaking? Drop one session per week and add moisturizer. Do not combine with retinol the same night.
If nothing happens after the full timeline, check product strength and whether you are protecting skin with SPF.
AHAs by skin type
The same ingredient behaves differently on different skin, so adapt the schedule rather than the product.
AHAs in a full routine
Here is how AHAs could slot into a simple day, given that it is best used evening.
Frequently asked questions
When should I apply AHAs?
Evening, after cleansing and before moisturizer.
How much AHAs is enough?
A thin layer — more does not speed results and raises irritation risk.
What if I miss a session?
Continue as normal; never double up.
Is it true that higher strength gives a bigger glow?
Not quite: overdoing it thins the barrier and gives temporary shine that fades into dullness.
