Full list of ingredients :
1. What are serums for?
Applying a serum before your day and night creams allows their effectiveness to be boosted. Caudalie serums are highly concentrated in active ingredients and can be used for daily use, morning and evening. Their lightweight textures absorb quickly into the skin, allowing the actives to penetrate effectively. For visible results and optimal skincare performance, a serum is an essential step.2. Is the Instant Firming Serum suitable for all skin types, including sensitive skin?
Yes, the Instant Firming Serum is suitable for all skin types, including sensitive skin. Its formula is tested under dermatological supervision and is non-comedogenic. Its anti-ageing active ingredient, vine resveratrol, is an alternative to retinol without its side effects.3. Is Instant Firming Serum suitable for use during pregnancy and breastfeeding?
Yes, the Instant Firming Serum is suitable for pregnant and breastfeeding women. Its anti-ageing active ingredient, vine resveratrol, is an alternative to retinol without its contraindications.4. Who is the Instant Firming Serum for?
The Instant Firming Serum is suitable for anyone looking for an anti-ageing serum that targets wrinkles, loss of firmness and lifts facial contours.5. What is a retinol alternative?
The Instant Firming Serum is a retinol alternative: it offers 3 times more firming action while being non-irritating. It is therefore suitable for sensitive skin or for those who do not tolerate retinol well.6. What are the active ingredients in the Instant Firming Serum and how do they work?
The Instant Firming Serum concentrates Caudalie's patented vine science (Caudalie x Harvard patent no. 1555116): vine resveratrol, derived from vine shoots and produced in France, stimulates collagen and elastin and activates sirtuins, the longevity proteins (sirtuin activation x128), alongside 2 hyaluronic acids. It is combined with Pro-Collagen Grape Multi-Peptides (500 peptides from grapeseed), making it the most active ingredient-concentrated product in the range.7. Is it true that the Instant Firming Serum is 3 times more firming than retinol?
Yes. Vine resveratrol, at the heart of the Instant Firming Serum, is the retinol alternative developed by Caudalie. Combined with Pro-Collagen Grape Multi-Peptides, it stimulates collagen production 3 times more than retinol, without its side effects. It can be used with sun exposure and is suitable for sensitive skin.8. How long does it take to see results from the Instant Firming Serum?
The Instant Firming Serum acts from the first application on skin firmness and facial contours. After 56 days of morning and evening use, the clinical study showed 10 years of firmness restored; 100% of volunteers noticed firmer, younger-looking and plumper skin.9. Can the Instant Firming Serum be applied in the morning before sun exposure?
Yes, the Instant Firming Serum can be used morning and evening and does not make the skin photosensitive: its anti-ageing active ingredient, vine resveratrol, does not have the side effects of retinol. Its formula is tested under dermatological supervision and is suitable for sensitive skin. As with any anti-ageing routine, apply sun protection in the morning.10. Where does the Instant Firming Serum fit into my routine?
Apply the Instant Firming Serum morning and evening to clean skin, on the face, neck and décolleté, before your cream. It is the first skincare step after cleansing and applying a lotion. In the morning, finish your routine with sun protection.

About the product: Instant Firming Retinol Serum
Nourishing serum for my usually sensitive skin
I really enjoyed this product - the smell is so delicate and the feel of the serum so nourishing to my menopausal skin. My skin is usually sensitive but this serum soothed it, helping it to look a bit fresher within a 2 week period. Will defo purchase the full size.

Love this serum!
Love how light-weight the serum is and it seems to be effective as a friend commented on how good like my face/skin was looking after about a month of using it.

About the product: Instant Firming Retinol Serum
Light, gentle, hydrating and protecting
I have been using this new serum formulation for around 6 weeks. It absorbs into my skin really well leaving no greasy residue and ready for moisturiser or SPF. Having used it across August - in an incredibly hot summer - I have noticed how hydrated my skin is, in comparison to other years. My skin feels soft and I haven't experienced any hyperpigmentation from the sun. I think the texture of my skin has improved but I am going to continue to use it before I can definitively say whether it is boosting collagen. However, I do think there has been some softening of lines around my mouth and chin/marionette lines.

About the product: Instant Firming Retinol Serum
It works!
When you have a husband who 'slaps creams on his face like butter on toast' and still gets great results, you get curious! So here I am, testing the serum in hopes of getting as 'pretty' as him - and it delivered. At 44, with wrinkles creeping in and my eyelids starting to feel heavy, I noticed a subtle but definite improvement around my eyes after just a week or so. I'm already planning to switch my day and night creams to the Caudalie line to see how well they complement the serum. Since my skin is quite sensitive and prone to reactions, I usually stick to what I know. But I was so pleasantly surprised - zero redness, zero irritation. Highly recommend it! My husband and I will definitely be buying one each.

About the product: Instant Firming Retinol Serum
Instant results
I’m currently 4 months post partum and recently started using this serum. I’m very happy with the radiance it gave within one week and the appearance of my large pores have seemed settled down. I’ll continue using it.

About the product: Instant Firming Retinol Serum
Excellent
I hadn’t tried the resveratol range before because I’ve always used the glycolic dark spot serum instead for my pigmentation but this serum really worked beautifully. My skin looked smooth and plump and really glowed. I’ll definitely be incorporating it into my skincare routine moving forward.
