Ulta's 21 Days of Beauty event is back for spring 2021, offering a range of skincare products at discounted prices. The event, which is highly anticipated by beauty enthusiasts, will showcase both the best and worst products according to customer reviews.

Among the best products featured in the event is the Clinique Moisture Surge 72-Hour Auto-Replenishing Hydrator. This moisturizer is praised for its lightweight formula and long-lasting hydration. Another standout is the Mario Badescu Drying Lotion, which helps to treat and prevent acne overnight.

On the other hand, there are also products that failed to meet customers' expectations.

The Murad AHA/BHA Exfoliating Cleanser was criticized for its high price tag and lack of noticeable results. The Benefit Cosmetics Total Moisture Facial Cream also received negative reviews due to its heavy texture and greasiness.

In addition to these specific product reviews, the article also mentions the event's format and structure. Each day of the event will feature different products, with some items being offered at a 50% discount. Customers are advised to check the Ulta website regularly to stay updated on the daily offerings.

Overall, Ulta's 21 Days of Beauty Spring 2021 - Skincare Edition provides an opportunity for customers to discover and try new skincare products at discounted prices. While there are both highly recommended and underwhelming products, the event promises to offer a wide range of options to cater to different skincare needs.
