Lancome Renergie C.R.X. Serum

The bottle keeps the three active ingredients—retinol, vitamin C, and peptides—separated until the moment you pump the product. This ensures the potency and stability of each ingredient, as they can sometimes degrade when mixed together in a single formula over time.

Because this serum contains retinol, it is potent. If you have sensitive skin, we recommend introducing it slowly—start by using it every other night to build tolerance before moving to daily application.

You can use this serum during either your morning or evening routine. If you choose to apply it in the morning, be sure to follow up with a broad-spectrum sunscreen, as retinol can increase your skin's sensitivity to the sun.

While this serum is designed to be effective, it is a treatment product rather than a heavy moisturizer. Depending on your skin type, you may want to layer a hydrating cream over it, especially if you have dry skin.

Yes, the combination of retinol and peptides is specifically formulated to help refine skin texture and improve the appearance of pores over time with consistent use.

It is generally best to avoid layering this serum with other strong acids or exfoliants to prevent irritation. If you want to use both, try alternating them on different nights or using one in the morning and one at night.
