We can’t stop raving about Cultiv, the ultra-desirable green beauty brand created by Laure-Anne de Tastes. Its star product? The HYDRA-BOOST serum, aka the ultimate weapon you need to face winter with your skin in top form. This brilliant booster complements your day or night cream, delivering what your skin silently craves. Its lightweight, ultra-absorbent texture sinks into the skin instantly, with visible effects from the very first application. After reviewing the most promising options, the verdict is clear: with its unbeatable quality-price ratio (€39), Cultiv's serum takes the crown!
Active Ingredients with Astonishing Efficacy
Cultiv has embraced a highly localized scientific approach by using by-products from French organic farming. Its ultimate discovery? Betaine, a miracle molecule found particularly in beets (organic and French, of course). Its role in the HYDRA-BOOST serum? To retain water in the superficial and deep layers of the skin, ensuring all-day hydration. But that’s not all: betaine stimulates the skin's natural mechanisms, improving its moisture balance over time. In short, the more you use it, the better your skin gets at staying hydrated—even if you skip a few days of serum.
The results speak for themselves: on a panel of 20 women, after 28 days of twice-daily application, skin hydration increased by 22%. These results were measured on bare skin at Day 0 and Day 28 (no cheating!) by an independent laboratory.
And because one hero ingredient isn’t enough to save your skin, this serum features a dream team of ultra-effective actives:
- Inulin, a precious prebiotic extracted from chicory, strengthens the skin’s hydrolipidic barrier to prevent dryness at the first sign of cold.
- Lutein and zeaxanthin, antioxidant chlorophyll pigments from spinach, expertly neutralize free radicals to protect your skin from premature aging.
- Ectoine, naturally found in vegetables, acts as a bodyguard against photo-aging and hyperpigmentation.
How to Use It for Flawless Skin
The perfect timing? Morning and evening, right before your favorite cream. Start with clean, slightly damp skin (pro tip: this boosts the absorption of active ingredients). One or two pumps are enough to cover your face and neck without wasting product. Its gel-cream texture is perfectly formulated to absorb quickly, leaving your skin soft, smooth, and hydrated without any greasy or sticky residue. To complete your routine, pair it with the Hydra Protect cream: a hydration and protection duo that optimizes your skincare results. With twice-daily use, expect the bottle to last around three months.
