Dos’s and Dont’s

Q1. Do I use this in place of toner?

A. Yes and no. While the mandelic water is not a toner, depending on if you feel that your skin needs the extra layer of hydration and protection that a toner provides, you can choose to use the mandelic water during the step you would toner, and skip toner as a whole. This is because the mandelic water, while it’s considered an exfoliator, works to also prep the skin as a toner would for skincare products applied afterwards.

Q2. What’s the main function of the Mandelic Acid 5% Skin Prep Water?

A. You can think of the Mandelic Acid 5% Skin Prep Water as an all-in-one face exfoliator. It not only improves the skin’s texture, brighten the skin tone and nourish the complexion.It exfoliates away dead skin for a more radiant appearance. The mandelic water also carries anti-inflammatory, antibacterial properties, making it effective on acne as well.

Q3. When/How many times can i use this?

A. You can use the Mandelic acid 3-4 times a week before using your toner, however if you have sensitive skin we would recommend you to use this product only 2-3 times a week. We advise you to gently wipe and pat the product on your face using cotton pad. (In the morning: please make sure to apply sun-lotion after using the product. we recommend to use AHA and BHA in your night time routine)

Q4. How should I store?

A. please keep it in a fridge or dark, cool and dry place in the room. For the best effect, use it all as soon as possible after opening the bottle.

Q5. What products should I stay away from when using this?

A. We recommend you don’t use this with other products that have exfoliating ingredients such as retinol, high concentration of vitamin C, AHA, BHA, and more. It may irritate your skin. Recommended using toner, serum and essence, and moisturizer after applying mandelic acid 5% prep water.

Q6. Is it suitable for teenager and pregnant woman?

A. For the teenager, Yes because It is produced based on reliable ingredients. so it can be used regardless of age / gender except for specific constitution. But We’d like to visit your own doctor with list of ingredients for pregnant woman for the more detailed diagnosis reflecting personal conditions.

    This is the best product if you have bumpy skin like i had, the physical exfoliator only remove dead skin cells from above surface, but it removes them from within, from my teenage i had bummy skin, but after using it my skin became even n soft Thank you beauty barn.

    Really good exfoliating product. Although it stings a little on first use my skin got used to it by the 3rd or 4th time. Sensitive skin types might want to be wary but a great product for acne care and pore care!

    Basically I am a scrub kinda person. So when I decided to try the Mandelic acid based chemical exfoliant, I needed to be very sure that it won’t irritate my skin but also does the job it claims. Very skeptical initially… After going through many reviews esp from youtube host Eunice of Wishtrend (huge inspiration). I decided to try this and my oh my this works wonders on my skin. The effects cN be seen the next day.. A smooth and plump skin. I use it twice a week for now may increase depending on skin condition.. A must try

    I have an oily and acne prone skin so I decided to try this one out. I’m reviewing as it’s been 2 weeks since I started using mandelic acid and so far I’m seeing good results, acne scars has gradually reduced N that’s definitely an improvement and I’m so…so… loving it.

    After a lot of research into AHA and BHA I finally decided to give this one a try. It stings a bit whenever i apply it but it is bearable and doesn’t cause redness or anything of that sort. My skin feels alot smoother the next day after i have used this. I usually use it twice a week followed by the Klairs Blue Claming Cream. A good alternative to harsh scrubs out there.

    After trying many exfoliating products, this is the only one that doesnt break me out. But does the job of exfoliating prefectly. Plus point- contains panthenol and licorice making it even more soothing for skin…highly recommend.

    This is the first Acid exfoliating product I had tried. It never irritated my sensitive skin. I was using it 1-2 times a week and my skin would look soft, bright and have less breakouts (the small zits we get). I am definitely gonna repurchase this in the future.

    I love this one so much. I can use it daily as I suffer from serious and it has never once caused a reaction of any sort! I have used it as recommended just on it own, before and after toner and every time I have achieved desired results. I can never part with this, it is gentle as well as effective.
    I was introduced to this one by a friend and her way of application is leaving it on for good 15mins and then applying anything on top. This way it helps absorption better and no wonder that is how I use it almost always!
