Key Ingredients and Their Benefits
LiftFirm
LiftFirm is a combination of cosmetic ingredients designed to provide an immediate smoothing and lifting effect. It helps improve the appearance of fine lines and wrinkles, leaving the skin looking firmer and more refined.
The formula includes Caesalpinia spinosa fruit extract and Kappaphycus alvarezii extract, which contribute to the product’s skin-smoothing and conditioning properties.
Q10 Peptide Complex
ISDIN highlights a Q10 peptide complex as part of Instant Flash’s energising and anti-fatigue approach. The ingredient list includes Pentapeptide-34 Trifluoroacetate, a peptide used in the formula to support its skin-conditioning benefits.
The manufacturer associates this complex with helping reduce the appearance of fatigue and promoting a firmer, more refreshed-looking complexion. The supplied ingredient list does not separately identify coenzyme Q10, so the complex is described here according to the product’s stated technology rather than as a confirmed standalone Q10 ingredient.
ContourBoost
ContourBoost is a combination of ingredients designed to help improve the visible appearance of ageing skin. It contributes to the product’s overall smoothing and firming cosmetic effect, helping the complexion look more refined and revitalised.
Hydrolyzed Hyaluronic Acid and Sodium Hyaluronate
These forms of hyaluronic acid help attract and retain moisture in the skin. By improving hydration, they can help soften the appearance of fine lines associated with dryness and leave the skin feeling smoother and more supple.
Glycerin and Propanediol
These moisturising ingredients help attract and maintain water in the skin, supporting immediate hydration and a comfortable, soft finish.
Biosaccharide Gum-1
Biosaccharide Gum-1 is a skin-conditioning ingredient that helps improve the feel of the formula on the skin and contributes to a smooth, comfortable finish.
Helichrysum Stoechas Extract
This botanical extract contributes to the formula’s skin-conditioning properties and complements the serum’s overall skincare approach.
Clinical and Consumer Results
According to manufacturer-reported cosmetic efficacy testing conducted in 2019, Instant Flash was evaluated in 30 participants under normal conditions of use. Participants applied the serum once daily, and the following results were reported within the first five minutes after application:
- 100% reported immediate hydration.
- 100% reported softer and smoother-feeling skin.
- 93% reported that the product reduced the appearance of fatigue and stress.
- 90% reported a lifting effect.
The manufacturer also references a 3D skin-mapping assessment using the Quantificare LifeViz Mini system to evaluate visible changes after application.
These results relate to a specific, small-scale manufacturer-reported assessment. They describe cosmetic effects observed or reported shortly after application and should not be interpreted as proof of permanent lifting or structural changes to the skin. Individual results may vary.
