In reply to Elisa. Elisa, you can use them together. As for pregnancy, experts disagree on whether AHAs are good for mom and baby. It really is a personal call.

Can I use Cosrx AHA 7 Whitehead Power Liquid if I also use the Paula’s Choice Niacinamide or I should put them on on separate moments? Also, can Cosrx AHA 7 Whitehead Power Liquid be used during pregnancy? Thanks!

Hi Claire,

1. I don’t care what brands say, if it can’t get into the pores, it can’t remove whiteheads. And glycolic acid can’t do that. If you have whiteheads, go with salicylic acid instead.
2. This depends on how dehydrated your skin is. Most people won’t need a separate hyaluronic acid serum if they use these exfoliants.
3. You can use either. A cotton pad would absorb some of the product while applying with your finger may provide some exfoliation to them too.
4. If the product has a good preservative system, it should last at least one year.

Hope this helps,

Hi Gio, I have a few questions regarding Glycolic Acid and Lactic Acid.
– Does all glycolic acid removes whiteheads & blackheads? Because I saw the word “whitehead” in the Cosrx AHA 7 Whitehead Power Liquid, does it means it can remove whitehead? Can I remove or prevent whitehead effectively if I use this product twice a week?
– The Cosrx AHA 7 Whitehead and The Ordinary Lactic Acid 5% + HA2% both has hyaluronic acid in them, does it mean I can skip my usual hyaluronic acid serum after applying either of these AHA products? Is there extra benefit for applying so much hyaluronic acid on our face from different products? Seems like most of the products (yes especially Korean products) already has HA, does it mean we do not need to purchase HA serum seperately?
– When applying any AHA products, should we use cotton pad to swap on our face or use our fingers to massage and tap them in? What’s the difference and does it matter?
– Does AHA products has a low stability formula? What products are usually in a low stability formula? i.e rosehip oil (use within 3 months)
Thanks Gio!
