Before making the investment in Dr. Sturm's Hyaluronic Serum or Augustinus Bader's face cream, see what beauty industry insiders actually think about these cult products.

For anyone in-the-know when it comes to <a href="https://www.lofficielusa.com/beauty/winter-skin-care-products-hydrating">skincare</a>, there are a select few products that have made it to cult status. First popularized by word-of-mouth testimonials from celebrities, aestheticians, makeup artists, and beauty editors, these prestige products&ndash;like Biologique Recherche&rsquo;s P50 Lotion and Dr. Barbara Sturm&rsquo;s Hyaluronic Serum&ndash;have now reached viral fame thanks to beauty influencers and social media. While these holy grail products are certainly buzz-worthy, they often come with exorbitant prices that make them beauty <a href="https://www.lofficielusa.com/fashion/handbag-resale-gucci-jackie-1961-purse">investments</a>. For those wondering whether they&rsquo;re actually worth it, L&rsquo;OFFICIEL consults several beauty industry insiders on the top five cult skincare products.

At the pinnacle of cult beauty products is the <a href="https://www.lofficielusa.com/beauty/biologique-recherche-p50-lotion" target="_blank">Biologique Recherche Lotion P50</a>. For decades, beauty editors and skincare junkies have sworn by the exfoliating liquid&#39;s skin-smoothing properties, despite its notoriously unsavory smell. Formulated to reduce dark spots, shrink pores, balance the skin&#39;s pH, and strengthen the epidermis, P50 is an anti-aging powerhouse. Skincare guru <a href="https://www.instagram.com/joannaczechofficial/?hl=en" target="_blank">Joanna Czech</a> has been using it for 25 years. &quot;[P50] is&nbsp;one of my must haves,&quot; she says. &quot;It controls the skin&rsquo;s pH and is a great micro-exfoliator.&quot; The celebrity aesthetician says it should be the first step after your nighttime cleansing. Co-founder of newly launched skincare brand Dieux <a href="https://www.instagram.com/charlotteparler/?hl=en">Charlotte Palermino</a>&nbsp;is also a fan, but warns against over-exfoliating and irritation. &quot;When you&#39;re using P50, don&#39;t use other exfoliators or resurfacing agents,&quot; she advises, adding, &quot;But on its own? Iconic for a reason.&quot;

Dubbed a <a href="https://www.thezoereport.com/p/augustinus-bader-the-rich-cream-might-be-265-but-derms-say-its-worth-every-penny-17023207" target="_blank">Miracle Cream</a>, this pricey and luxurious moisturizer has earned praise from a long list of beauty industry pros and celebrities, including <a href="https://www.lofficielusa.com/pop%20culture/david-beckham-boots-victoria-beckham-instagram" target="_blank">Victoria Beckham</a>&nbsp;and <a href="https://www.lofficielusa.com/film-tv/margot-robbie-confirms-harley-quinn-movie" target="_blank">Margot Robbie</a>. Czech says its worth the $265 price tag: &quot;The consistency is great and the repairing effects of the TFC8 Complex address every skin condition.&quot; The special complex she speaks of contains a mixture of nourishing vitamins, natural amino acids, and synthesized molecules, which help The Rich Cream stimulate stem cell production, and thus deliver glowing skin. <a href="https://www.instagram.com/storyofmailife/?hl=en">Mai Quynh</a>, makeup artist to <a href="https://www.lofficielusa.com/fashion/chloe-grace-moretz-is-all-grown-up" target="_blank">L&#39;OFFICIEL star Chlo&euml; Grace Moretz</a> and other starlets, vouches for the cream&#39;s holy grail status, sharing that the product &quot;evens out my skin tone and takes away any redness and dark spots, making it look younger and healthier.&quot; She also uses it on the job, as it is the perfect texture for day or night and &quot;works well under makeup.&quot;

La Mer&#39;s luxe skincare line has a&nbsp;<a href="https://www.vox.com/the-goods/2018/10/10/17957586/la-mer-creme-de-la-mer-chinese-lawsuit" target="_blank">polarizing reputation</a>&nbsp;thanks to its lofty prices&nbsp;and some questionable ingredients (a cosmetic chemist once determined that Cr&egrave;me de la Mer&#39;s ingredients cost only a little over $20). Like its favorite face cream, The Concentrate is made&nbsp;to soothe skin and aid in anti-aging. Seasoned makeup pro <a href="https://www.lofficielusa.com/beauty/gucci-westman-to-launch-clean-6-piece-beauty-collection-westman-atelier" target="_blank">Gucci Westman</a>&nbsp;doesn&#39;t buy it, though. &quot;This wouldn&#39;t personally be something I would put on my skin,&quot; she says. Because it contains potentially irritating ingredients like&nbsp;lime peel extract, limonene, and phenoxyethanol, the <a href="https://www.westman-atelier.com/" target="_blank">Westman Atelier</a> founder and celebrity MUA is wary of products that may agitate her rosacea.

Considered the&nbsp;cr&egrave;me de la cr&egrave;me, this&nbsp;<a href="https://www.lofficielusa.com/wellness/9-benefits-of-vitamin-c-you-did-not-know" target="_blank">Vitamin C</a> serum from no-nonsense, science-backed skincare brand Skinceuticals&nbsp;combines antioxidant ferulic acid with pure Vitamins C and E to protect skin against environmental factors like pollution and free radicals from <a href="https://www.lofficielusa.com/beauty/broad-spectrum-sunscreen-beauty-skincare-travel" target="_blank">UVA/UVB</a>. With consistent use, the serum treats fine lines, hyperpigmentation, and loss of firmness. Palermino vouches for the product&rsquo;s effectiveness and its top-notch ingredients. &ldquo;Trying to find a good dupe is like trying to cook a recipe with an ingredient list, it&#39;s hard and takes a lot of [research and development],&rdquo; she says. &ldquo;When Skinceutical&#39;s patent is up maybe then we&#39;ll see a good replica, &lsquo;till then, it&#39;s one of the best skincare products&nbsp;on the market for a reason.&rdquo;&nbsp;

One of the <a href="https://www.sephora.com/product/dr-barbara-sturm-hyaluronic-serum-P447212" target="_blank">best ingredients to save dry skin</a>,&nbsp;hyaluronic acid helps the skin retain moisture.
