Frequently Asked Questions Answered by Biologi
Q. Can I use a moisturiser over the top?
A. We don't recommend using a moisturiser over any of our Biologi serums. Biologi is a 100% water solouble extract and because most moisturisers contain a high level of water, mixing them will actually dilute the potency of your Biologi serum. It's also an unnecessary step as our serums are so hydrating, you simply don’t need anything else.
Q. Can I layer the Biologi serums ?
A. We don’t recommend that you use any other products on top of Biologi other than your daily SPF. We also don’t advise layering any of our serums on top of each other. This is because the serums are 100% pure plant extracts and they actually don’t “like” each other. For e.g if you were to layer the BD face and BK eye serum, the amount of vitamin C going into the skin would be decreased or cancelled out. If you were to start using the luminosity serum we would suggest using it all over your face, first point of contact after cleansing. Our serums are 100% active and really potent and they replace your serum and moisturiser.
Q. Why does my skin feel tacky after I use the serums ?
This is completely normal !
When skin cells are first exposed to active ingredients, you might experience a purging process. This is the toxins being expelled from the cells, and while you might notice spots, breakouts or a sticky texture on the skin, purging is definitely a good thing!
The skin purge can last up to four weeks or in many cases; it may not happen at all. Purging is a short-term effect of using actives to treat the skin on a cellular level. We encourage you to persevere as once your skin is completely purged; you’ll be left with hydrated, glowing skin.
Q. Are Biologi serums safe for pregnancy ?
A. Yes absolutely. Biologi is 100% safe for pregnancy, breastfeeding and our BF body serum is also safe to use on babies. You can read more here
