A serum displayed at half price, an “exclusive” set that returns every month, a countdown that never stops: beauty offers are abundant online, but not all are created equal. Distinguishing a genuine discount from a mere marketing gimmick requires some precise reflexes, much more useful than waiting for the next flash sale.
Strikethrough pricing in cosmetics: what the law really requires
You may have noticed that a discounted product sometimes displays an oddly high “previous price”? Since May 28, 2022, the rule is clear. The reference price must be the lowest price applied in the 30 days prior, both in-store and online. This obligation stems from Article L112-1-1 of the Consumer Code, transposing the European Omnibus directive.
In practice, a retailer can no longer inflate a price two weeks before a promotional event to simulate a spectacular discount. The previous price displayed must correspond to a price actually applied during the reference period.
To verify, a simple method: take a dated screenshot of the price before the promotion. Some online tools also allow you to track the price evolution of a product over several weeks. If the “before discount” price was never applied, the promotion is misleading.
By exploring the good deals on Le Blog Beauté, you will find selections that mention the conditions of each offer, making this verification process easier.

False beauty promotions: three concrete warning signs
Inspections by the DGCCRF on strikethrough prices remain a current topic, and cosmetics are no exception. Certain mechanisms recur regularly.
The permanent countdown
A timer running on a product page creates a sense of urgency. When this same timer resets every day, the urgency is fictitious. A “last chance” offer repeated endlessly may constitute misleading commercial practices.
The endless private sale
Some retailers display “private sales” open to everyone, repeated week after week. The word “private” loses its meaning when any visitor can access it without conditions. The reliable signal: a start date, an end date, and a discount that actually disappears after the announced deadline.
The recommended price as a reference
A comparison price based on a competitor’s rate or on a “price recommended by the brand” does not constitute the legal previous price. Only the lowest price practiced by the seller themselves over 30 days counts. This distinction is often buried in the fine print.
- Check that the strikethrough price corresponds to the rate of the same seller, not that of another retailer.
- Ensure that the validity period of the offer is clearly displayed on the product page.
- Beware of “exclusive” promo codes shared on dozens of sites simultaneously.
Beauty shopping routine: optimizing your budget without sacrificing quality
Waiting for sales or Black Friday is not the only strategy. A few regular habits can help reduce your cosmetic bill without changing brands or skimping on the quality of products.
Travel sizes and miniatures are an underestimated lever. Before investing in a full bottle of serum or cream, testing the smaller version can prevent disappointing purchases. Several brands offer discovery kits whose content-to-price ratio is sometimes more advantageous than the standard size.
Multifunctional products also deserve your attention. A tinted balm that acts as a foundation, moisturizer, and sunscreen replaces three distinct products. The gain is not only financial: fewer bottles also mean less waste.

Compare INCI lists rather than brands
Two hyaluronic acid serums can have very different prices for an almost identical composition. The INCI list (International Nomenclature of Cosmetic Ingredients) must appear on every package. Reading the first five ingredients is often enough to determine whether a high-end product truly stands out from a more accessible alternative.
An active ingredient like retinol or niacinamide remains the same regardless of the brand that packages it. What varies is the concentration, formulation, and excipients. Comparing these elements takes a few minutes and can save you several dozen euros a year on a complete routine.
- Identify the position of the star active ingredient in the list: the higher it is, the higher its concentration.
- Spot irritating excipients (denatured alcohol at the top of the list, synthetic fragrances) that do not justify a high price.
- Consult detailed reviews that mention texture and skin tolerance, not just packaging.
Beauty offer calendar: periods worth noting
Not all promotional periods are equal in cosmetics. Winter and summer sales remain the times when discounts are legally regulated, with gradual reductions over several weeks.
Year-end gift sets often represent good value for money. Brands bundle several formats (care, fragrance, accessory) at a price lower than the sum of the products purchased separately. Checking that each product in the set meets a real need helps avoid accumulating unused bottles.
Outside of these key times, the launch of new products sometimes comes with discovery offers. These launch promotions are occasional and rarely repeated, making them generally reliable discounts.
The most cost-effective reflex remains to build your wishlist in advance and only purchase when the targeted product goes on sale. Buying a product you don’t need just because it’s discounted is never a saving.
