What is the best way to use this Serum: on its own or with gel-cream?

Hello Ludmila, Thank you for your question. Vitamin C and hyaluronic acid are a perfect combination as they create a more effective skin care routine when used together. Therefore, you can safely use them together as part of your morning and night routine. I personally apply vit c serum first (after cleansing and toning) to a damp skin and after a few seconds, before my serum dries out, I follow with the Hyaluronic Acid Gel-Cream. It is really important that hyaluronic acid products are applied to not completely dry skin. If applied to a very dry face, they can actually end up drawing moisture from the deeper levels of your skin, which may leave your complexion feeling tight and uncomfortable. It is also important to always listen to our skin needs, sometimes our skin is prone to dryness and needs extra love so especially in the evening routine, I sometimes apply extra layer or moisturiser to provide an extra barrier against moisture loss. We are currently working on new products that will be available soon and one of them is an amazing face cream called TSU:SEI Rose Hydro Cream which works magic at night. It is specifically adapted for sensitive skin prone to dryness, fatigue and fine lines. Even though its texture is richer, it is still fast absorbing and doesn’t leave a greasy film. Thanks to this, it is a great product for a day time routine as it has SPF20 that protects your skin against the damage caused by daily exposure to UVA and UVB rays. Kind regards The TSU:SEI team.

How long does this product take to work ? (mainly just to get a nice clear face glow) Also do you apply it night and day

Hello, Thank you for your question and interest in our product. To answer your question it all really depends on each individuals skin type and how well your skin reacts to the product. Regular application is key to seeing the benefits, you will feel that the skin is enriched almost after the first few days but as it is a natural product, it takes few weeks of regular application until your skin fully feels the benefit from it. We recommend application day and night to see maximum benefits, we also recommend to use in combination with our Hyaluronic acid gel-cream, applying our Pure Vit C serum first then the gel-cream after. Both these products used combined will give you that clear face glow you seek. Fast results are usually achieved by adding chemicals to products which will never appear on the TSU:SEI ingredients lists. I hope this answered your question, If you have any further questions please don’t hesitate to contact us. Kind regards The TSU:SEI team.

What form of Vitamin C is in the ingredient (e.g. asorbic acid) ?

Hi, It’s Magnesium Ascorbyl Phosphate (MAP), which is is a water-soluble, non-irritating, stable derivative of Vitamin C. MAP offers specific skin brightening benefits, more so than other derivatives of Vitamin C. Protects the skin from free radicals, stimulates collagen production, reduces hyperpigmentation, and maintains skin hydration. It is also important to note that MAP is a better choice than Ascorbic Acid for people with sensitive skin and those wishing to avoid any exfoliating effects since many Vitamin C formulas are highly acidic (and therefore produce exfoliating effects). Please let us know if you have any more questions. Kind regards TSU:SEI Team
