Beauty offers are multiplying online, but not all are created equal. Between seasonal promotions, end-of-line sales, and discounted launches, sorting through them relies on specific criteria: product composition, regulatory compliance, and compatibility with an existing routine. Understanding these criteria before comparing prices helps avoid unnecessary purchases and disappointments.
Regulatory compliance of cosmetics in France: what has changed
Since January 1, 2026, French law n° 2025-188 prohibits the manufacture and sale of cosmetics containing PFAS (per- and polyfluoroalkyl substances). These compounds, long used for their waterproofing and smoothing properties, were found in certain foundations, waterproof mascaras, and long-lasting creams.
This ban significantly alters the landscape of promotions. A discounted product with a formula dating from before 2026 may contain PFAS without the label clearly indicating it. Checking the INCI list before purchasing a skincare or makeup product on promotion protects both the skin and the wallet.
On the packaging side, the European Regulation (EU) 2025/40, which came into effect on February 11, 2025, and is applicable since August 12, 2026, regulates the conditions for a packaging to be classified as reusable. Multiple rotations, the possibility of emptying and refilling, health safety, and consumer information are part of the requirements.
A bottle labeled “refillable” that does not meet these criteria can no longer legally carry this mention. By browsing the offers provided by Ulta Beauté, one can filter products according to these new standards to ensure the compliance of selected references.
Discounted face care: active ingredients to prioritize according to skin type
Faced with a page of promotions featuring dozens of serums and creams, the natural reflex is to compare discount percentages. The useful reflex is to compare the active ingredients.
Dry and dehydrated skin
Hyaluronic acid remains the go-to active ingredient for hydration. Its ability to retain water in the superficial layers of the epidermis makes it a recurring component in low-priced serums. An effective hydrating serum combines several molecular weights of hyaluronic acid to act at different depths.
Shea butter and squalane complement this base well by reinforcing the skin barrier. A cream on promotion that combines these three ingredients meets the needs of dry skin without multiplying products.
Combination to oily skin
Niacinamide (vitamin B3) regulates sebum production and tightens visible pores. When combined with a gentle exfoliant like salicylic acid (BHA), it forms a duo suitable for blemish-prone skin.
Some brands like The Ordinary offer concentrated serums at reduced prices year-round. During promotional periods, checking the expiration date is the first step before adding to the cart: an opened serum loses effectiveness after six to twelve months depending on the formula.
Discounted makeup: spotting quality behind the crossed-out price
Makeup represents a significant portion of online beauty offers. Lipsticks, foundations, palettes: discounts often exceed half the original price at the end of a collection. Three points deserve systematic verification.
- The texture and pigmentation depend on the concentration of pigments and film-forming agents. A discounted lipstick that mainly contains cheap waxes and little pigment will not last on the lips, even at a bargain price.
- The limited color range on promotion sometimes pushes one to choose an unsuitable shade. It’s better to pass than to accumulate products that are never worn.
- Discounted organic and natural cosmetics must display a recognized label (Cosmos, Ecocert, Natrue). Without certification, the mention “natural” on packaging has no regulatory value.
A fluid foundation formulated without PFAS, compliant with the 2026 law, offers coverage comparable to older formulas. Brands have reformulated their ranges to maintain wear without these compounds, and consumer feedback confirms that the transition has occurred without a notable loss of performance.
Refillable cosmetics: a real lever for long-term savings
Refills are no longer a marketing argument reserved for luxury. They represent a concrete saving when regularly purchasing the same skincare or makeup products.
French consumers are already adopting refills in their daily routines, not just out of ecological conviction. The price of a refill is on average significantly lower than that of the complete product with its container. Over a year, for a face care product used morning and night, the cumulative savings justify the initial investment in a reusable bottle.
The European Regulation (EU) 2025/40 now requires that the refillable container withstand multiple filling cycles without degradation. This framework eliminates false refillables (fragile bottles designed for one or two refills). Before purchasing a container presented as refillable on promotion, checking that it carries the compliance mention to the regulation protects against unpleasant surprises.
Building a coherent beauty routine from promotions
Smart shopping does not mean buying everything that is discounted. An effective routine relies on four to five complementary products, not on a dozen overlapping treatments.
- A cleanser suitable for the skin type (cleansing oil for dry skin, foaming gel for combination skin) forms the base.
- A targeted serum (hydrating, anti-blemish, or antioxidant according to needs) provides the concentrated active ingredient.
- A protective moisturizing cream seals in hydration and strengthens the skin barrier.
- Daily sun protection, even in autumn, completes the skincare routine.
Promotions on complete ranges (cleanser, serum, cream from the same brand) allow testing a coherent routine at a lower cost. Compatibility between formulas in the same range reduces the risk of interaction between incompatible actives, such as the simultaneous use of retinol and exfoliating acids.
The French cosmetics market continues to evolve under the combined effect of new regulations and consumer expectations for transparency. Choosing a beauty offer by verifying regulatory compliance, the relevance of active ingredients, and the durability of packaging transforms a simple promotion into a truly useful purchase for both the skin and the budget.
