1. Start with a clean, dry face

After thoroughly cleansing your face, pat your skin dry. This ensures the BHA can penetrate effectively without interference from other products or impurities.

2. Apply to skin with a cotton pad

Apply a suitable amount to a cotton pad and gently swipe across your face, avoiding the delicate eye area. Alternatively, dispense a few drops onto your palms and gently press into the skin.

This toner has truly been a game-changer for me. Having tried various toners in the past, I can confidently say that this one stands out. Its unique texture, unlike the typical watery consistency, resembles more of a rich, milky emulsion. After cleansing, my skin tends to become quite dry, but this toner immediately provides the moisture it craves. Dealing with mild acne and persistent blackheads on my nose, I was pleasantly surprised that this product didn't exacerbate my acne issues. In fact, I noticed some visible improvements in the reduction of blackheads on my nose.

Provably the gentlest BHA I’ve used but it still seems effective. A lot less irritating than Paula’s BHA. I’ve used it before and as my skin gets drier I prefer a BHA cleanser. Even though be careful around the eyes as it is very irritating to the eyes. TIP: wait at least 10 to 15 minutes before adding your moisturizer! For salicylic acid, it is said improvements come in about 4 weeks time.

I wish it came in a jumbo size! Better than the Paula's choice one and gentler! I like to apply it once a week on cotton pads and leave it on for 10mins on my cheeks, forehead and chin! worth the hype. It's a really gentle exfoliation that won't damage your skin barrier. I have really sensitive oily skin prone to flakiness when exposed to excessive exfoliation.

I use this once or twice per week, although it’s super gentle. I had no irritation using this, it helped keep my face clear and get rid of small blackheads. My skin and forehead area have cleared up when using this product. Whenever used at night the next day you wake up with shiny skin which is great. Would recommend.

Your questions answered

Understanding how chemical exfoliation fits into your routine is key. Here, we address common concerns about frequency, skin compatibility, and how this BHA toner interacts with other products to help you use it effectively and safely.
For best results, the Isntree Chestnut BHA 2% Clear Liquid should be used no more than three times a week. If you are new to BHA or have sensitive skin, start by using it once or twice a week, then gradually increase frequency as your skin tolerates it.
Yes, this formula is designed to be gentle. It contains hydrating hyaluronic acid to support the skin barrier while exfoliating. However, if you have very sensitive skin, it’s always wise to patch test first and introduce it slowly into your routine.
Apply after cleansing. Dispense onto a cotton pad or palms and gently press or swipe across the face, avoiding the eye area. It’s recommended to wait 10-15 minutes before applying subsequent moisturizer to allow the BHA to work effectively.
It’s generally advised to avoid using multiple exfoliants, such as AHAs, BHAs, or retinoids, in the same routine session to prevent over-exfoliation and irritation. You can alternate this BHA toner with other actives on different days.
The toner has a unique, slightly milky texture that is not as watery as typical toners. It absorbs quickly into the skin, leaving a comfortable, hydrated feel without a heavy or sticky residue, making it suitable for layering.
No, BHA (salicylic acid) does not increase sun sensitivity in the same way AHAs do. It has some mild UV-absorbing properties. However, wearing daily sunscreen is always recommended to protect your skin and maintain results.
