In short: a skin care routine for sensitive skin works best when it is short, gentle and steady.
With Repêchage Hydra 4, that means a mild cleanser and a soothing tonic morning and night, Red-Out Serum on areas that look red, a light day cream, and a soothing mask two or three times a week, with a gentle broad-spectrum sunscreen every morning. Introduce one product at a time and patch test first. This guide sets out the routine and how to build it slowly.
What sensitive skin means
Sensitive skin is not a single type. It describes skin that reacts easily: it may sting with new products, flush or look red, feel tight or itchy, or react to heat, cold, sun or pollution. It can sit on top of any skin type, from dry to oily. Some redness and sensitivity comes from conditions such as rosacea or eczema, which need a dermatologist's advice alongside a gentle routine.

At night, after the serum, use a gentle moisturizer that suits you. If your skin is also dry, the fragrance-free Hydra Dew Pure Facial Moisturizer is made for dry, compromised skin.
What is in the Hydra 4 range
The collection is built on four seaweed extracts, with soothing botanicals such as chamomile, St. John's wort, green tea and olive. Red-Out Serum adds Laminaria digitata seaweed and silver, with rutin and quercetin, and is made for both day and night use. For a gentle cleanser focused on redness, there is also Red-Out Calming Cleanser.
How to introduce a new routine to sensitive skin
- Patch test. Apply a small amount on your inner arm or behind the ear for a day or two. Stop if you see redness, itching or swelling.
- One product at a time. Start with the cleanser, then add the next product every few days.
- Keep it simple. Avoid adding scrubs, strong acids or fragranced products while your skin settles.
- Watch and adjust. If anything stings, stop that product and go back to the steps your skin is comfortable with.
Start with the Hydra 4 Starter Kit
The Hydra 4 Starter Kit brings together the cleanser, soothing toner, Red-Out Serum, day cream and soothing clay mask in smaller sizes, which suits slow introduction. See the full range on the Hydra 4 page.

Everyday habits for sensitive skin
- Wash with lukewarm water, never hot, and pat skin dry with a soft towel.
- Avoid rubbing, rough cloths and scrubs.
- Protect your skin from sun, wind and heat; sudden temperature changes can trigger redness.
- Choose fragrance-free makeup and sunscreen where you can.
- Keep a note of what triggers a reaction, so you can avoid it.
If you enjoy a facial massage, keep it to light pressing on reactive days. Our guide to face massage at home explains when to skip it.
When to see a dermatologist
See a dermatologist if redness is constant, comes with visible small blood vessels, bumps or burning, if your skin flares often, or if you have patches of eczema or psoriasis. A gentle routine supports the skin, but these conditions need a medical plan.
