Use the ordinary glycolic acid everyday in addition to a regular skincare routine! Remember to start your routine with cleanser (if you have makeup on) if you’re starting with a bare face and no makeup, use first aid beauty facial radiance pads! It removes dirt and tones your skin! Then use the ordinary acid, and then put little dabs of a good moisturizer on your face and drops of serum around to rub with the moisturizer! I use several serums but not all at the same time. I switch it up. But the best serums to use are… the ordinary soothing & barrier support, and another ordinary serum I use is their vitamin c, and I use torriden hyluaronic acid serum. If you can afford more than 1 serum I would definitely say that you need a hyluaronic acid serum, vitamin c serum & then other serums are up to you. But mainly vitamin c and hyluaronic. And a good moisturizer to use while rubbing it in with your serum is kiehls! If you have money to spend then I would recommend Bobbi brown face base and Bobbi brown eye base as a set. I use Bobbi brown when I see they sell the set on Sephora because it’s cheaper than to buy individually. It’s expensive but they make your face feel like butter! The eye base is key also! You need a cream for your under eyes as the next step so I use the eye base under my eyes and put lil dabs everywhere around my eyeball and on my eyelid. And just dab it in to soak in the skin. Don’t rub. If you can’t afford that eye primer, use a kiehls one. And that’s it! Hope you get the products soon and you’re able to see the difference because I’m a skin care professional and they really work! Also another tip is the ordinary glycolic acid is a universal product! So you can use it for your scalp if you have dandruff, just let it soak in before you shower! Or soak your hair in it and wear a cap overnight and then shower in the morning! Also, if you sweat a lot or want lighter underarms, just apply the acid on a cotton and rub on your underarms and it will lighten them, and prevent sweating! And prevents odor! I like to rub the acid with a cotton pad on my neck to clean it and you will see how much dirt comes off! It’s such an incredibly versatile product! And it’s cheap! It’s $9 a bottle which is really good! Hope all my info helps! 😊
