OSKIA Liquid Mask
OSKIA's Liquid Mask covered in pink liquid

"Nothing beats acids for rejuvenating the skin. Not all acids are made equal and not all suit everyone or every skin type. I don’t believe that mixing lots of different acids is the answer, so I’ve formulated a single-acid treatment using, in my view, the Queen of all acids - Lactic Acid. I have never felt my skin so soft, my pores so refined and my skin so glowing after using this product. Happy doesn’t even come close. No more good skin 'days', but months and years! Extracted from sugar beet, it’s the one acid that can be used regularly by all skin types, even those who might usually avoid acids. Not only does it resurface, but it also boosts skin hydration, which is ideal for sensitive skins. We use the maximum % of Lactic Acid recommended under EU guidelines and at the correct pH level to ensure Liquid Mask is not only a highly effective acid treatment that offers amazing results quickly but it’s also 100% safe and a pleasure to use".

Who is this product recommended for?

All skin types, even those who might usually avoid acids. For those with particularly sensitive skin, Liquid Mask can be applied and then rinsed off after 5-10 minutes.

Which ingredients will help to calm and condition my skin alongside the Lactic Acid in this prduct?

We have used patented Cactus Stem extract in this product to calm the skin and added Pro-Vitamin B5 and MSM too, to condition while preventing any irritation.

Should I use a moisturiser on top of this product when wearing it overnight?

You can follow this product with your usual night-time skincare routine, but our top tip to make the most out of this product is that you should ideally allow around 5-10 minutes before applying any other products to the skin after applying Liquid Mask; the longer the better. This is because when the Lactic Acid comes into contact with another product it is neutralised, so the longer you can leave the product before layering, the more efficient it will be and the more time it will have to work. It is also absolutely fine to apply Liquid Mask and leave it on its' own overnight, as the Hyaluronic Acid, Pro-Vitamin B5 and Cactus Stem extract already provide hydrating and conditioning benefits for the skin.

Is this product suitable for vegans?

Yes, this product is suitable for vegans.

Does this product contain parabens?

This product is FREE FROM any artificial chemicals, fragrances, preservative, colorants, petrochemicals, phthalates, DEA, TEA, sulphates or parabens.

Is this product gluten-free?

This product is free from gluten and all traces of gluten.

Can this product be used during pregnancy?

The entire OSKIA range is suitable to use during pregnancy apart from our Super-R, MSM Bio-Plus, Lactoferrin+ & Vitamin E Bath Oil. OSKIA is a natural skincare range and we use a very small quantity of organic essential oils in our products to give them a very light but lovely fragrance. As the organic essential oils are in very small quantities, they are perfectly safe to use during this very special time. For your peace of mind, if thinking of trying any of our supplements, please do consult your General Practitioner first.

Once I open this product how long can I use it for?

This product can be used for up to 9 months after initial use.
