With 1% Caffeine, energy in every drop.
Caffeine helps stimulate the skinβs surface, supporting a more toned, refreshed and awake appearance. In this lightweight gel, it works synergistically with hydrating actives to reduce the look of puffiness and tiredness. The result: skin that feels energised, appears smoother and glows with renewed vitality.
Two forces. One refreshing balance.
Organic glycerin and alcohol provide a light, refreshing base that supports hydration and smooth application. Cellulose gum and algin form a natural gel matrix, helping to retain moisture and enhance the cooling feel on the skin. Subtle notes from natural essential oils complete this energising blend, leaving the skin fresh, soft and comfortably revitalised.
Good skin? happy customer!

Who says Yelf is only for women? The hyaluronic gel is my favourite after-shave product: it absorbs quickly and refreshes immediately. It does exactly what I want from modern skincare products. Plus, it looks stylish in my bathroom π

Aging Bye Bye has completely changed my routine. I have very fair and sensitive skin and have difficulty with many products. My skin now looks much healthier. And I think it's great that Yelf is vegan and cruelty-free... that's how they should all be!
How to use?
01.
Use morning and/or evening on freshly cleansed skin to awaken dull or tired areas and boost microcirculation.
02.
Smooth a thin layer over the face or focus on specific zones such as under the eyes or around the temples β alternatively, mix a small amount into your face or eye moisturizer for an energizing effect.
03.
Allow the lightweight gel to absorb completely as caffeine and botanical actives help to reduce puffiness, invigorate the skin and promote a refreshed, radiant appearance.
04.
For lasting hydration and a smooth finish, combine with Yelf. Aging Bye Bye Hyaluron Eye Cream and Yelf. Aging Bye Bye Hyaluron Eye Cream to seal in moisture and enhance the skinβs vitality throughout the day.
