Product Information
Full details
The Isntree Hyper ACID4 Serum is a potent exfoliating treatment designed for adults looking to address uneven skin tone, clogged pores, and excess sebum. By combining a 30% blend of AHA, BHA, PHA, and LHA, it effectively accelerates cell turnover to reveal a clearer, smoother complexion, though its high concentration makes it unsuitable for those with highly sensitive or compromised skin barriers.

FAQs
How often should I use the Hyper ACID4 Serum?
Due to the 30% acid concentration, it is recommended for use only in your nighttime routine, typically 1-2 times per week depending on skin tolerance.
Can I use this if I have sensitive skin?
This product is not recommended for sensitive skin. Always perform a patch test on your inner arm 24 hours before applying to your face.
Should I apply a toner before this serum?
It is best applied to clean, dry skin to ensure even application and minimize the risk of unpredictable absorption.
What should I do if the serum gets into my eyes?
Rinse immediately and thoroughly with lukewarm water. If irritation persists, consult a medical professional.
Is it necessary to use sunscreen the next day?
Yes, exfoliating acids increase skin sensitivity to the sun. Always apply SPF 30 or higher during the day following use.
Troubleshooting
Skin feels excessively tight or stinging after use.
Reduce the massage time to 30 seconds and increase the interval between treatments; follow immediately with a thick barrier-repairing moisturizer.
Serum is difficult to spread.
Ensure the skin is clean and slightly damp, or apply one additional drop to help with slip during the massage.

Setup, Compatibility & Care
Before using this serum, ensure your skin is clean and completely dry to prevent uneven absorption. Because of the high acid content, do not combine this with other potent actives like Retinol or Vitamin C in the same routine, as this will lead to irritation. Always store the bottle in a cool, dark place away from direct sunlight to preserve the integrity of the formula. After rinsing, it is highly recommended to follow up with a gentle, hydrating moisturizer to replenish the moisture barrier.
