Vitamin B3, B5 and Hyaluronic Acid Hydrating Serum

Starting with our Vitamin B3, B5 & Hyaluronic Acid Hydrating Serum packed with nourishing ingredients including 12% Niacinamide (Vitamin B3), to promote a healthy skin barrier to aid in the reduction of trans epidermal water loss, through stimulating the production of ceramides which make up a large portion of our skin barrier. While we want to promote the production of ceramides, we have also included them as an ingredient in the serum to immediately improve barrier function. As well as 1% Panthenol (Vitamin B5) and Glycerine that act as both humectants and emollients to lock in moisture to retain hydration levels within the skin leaving it soft and supple, noticeably reducing the appearance of fine lines and wrinkles. This nourishing serum with its 3 varying molecular weights of Hyaluronic Acids, another humectant which is widely used in skincare due to its ability to attract up to 1000x its molecular weight in water allows for immediate hydration as well as deeper and longer lasting effects as the smaller molecular weights as able to penetrate further into the dermis.

 Along with Sodium PCA which occurs in our skin as part of its natural moisturising factor acting as another humectant to attract and retain water to maintain hydration. Sodium PCA achieves superior hydration without causing a thick or occlusive product adding to the benefits or our much-loved hydrating serum. This combination of ingredients hydrates and plumps, visibly reducing the appearance of lines and wrinkles associated with ageing skin.

15% Vitamin C Lustrum Serum

Secondly, we have the 15% Vitamin C Lustrum Serum to follow the hydrating serum daily. The 15% of Vitamin C is optimal range for efficacy without irritation. We have included the Vitamin C in five potent forms which are L Ascorbic Acid, a pure form of Vitamin C, Ethyl Ascorbic Acid and Sodium Ascorbyl Phosphate, both known for their stability (Vitamin C is notoriously unstable), Ascorbyl Tetraisopalimitate, an oil-soluable form of Vitamin C that is able to penetrate deep within the skin for effective long-lasting results. The last form of Vitamin C is Terminalia Ferdinandiana, derived from Kakadu plum and is a low irritant form of Vitamin C. Vitamin C is known for its powerful antioxidant properties, providing superior protection against free radicals and environmental stressors. It also proven to promote collagen production within the skin whilst also protecting existing collagen from damage to combat the ageing process.

 Our serum also contains Ferulic Acid and Vitamin E, more antioxidants that aid in photoprotection of the skin, each of these actives enhances the antioxidant properties of the other creating visible improvements to skin brightness and minimising the degradation of collagen and elastin. Ferulic Acid also further aids in stabilising Vitamin C. Along with ingredients likes Arbutin that inhibits melanin production and Milk Thistle and Bearberry Leaf Extract, natural calming extracts that provide further antioxidant protection. The formulation also includes Uplevity Firming Peptide, which as its name suggests, helps to firm and plump the skin through collagen synthesis as well as assisting in collagen and elastin assembly, improving the quality of the extracellular matrix, creating a plump, youthful appearance. 

By limiting the damage of free radicals to the skin while also inhibiting melanin production, plumping and calming this serum gives visible antiaging results with firmer and brighter looking skin.

12% AHA BHA Exfoliating Serum

Exfoliating the skin with our 12% AHA BHA Exfoliating Serum 2-3 times per week will help to renew the skin by break down older, dull cells and promote newer, undamaged cells resulting in a brighter complexion. While also creating smoother looking, soft to touch skin as this leave on serum combines a range of Alpha Hydroxy Acid (AHA) and Beta Hydroxy Acid to completely revitalise the skin. These include 5% Lactic Acid (an AHA) derived from milk, which removes dead skin cells from the surface, promoting cell turnover, creating a brighter appearance and refined texture. With 2% Mandelic Acid (an AHA), derived from almonds which allow for further exfoliation and cell turnover while being gentle on the skin thanks to its large molecular size. Then we add 2% Glycolic Acid (an AHA) derived from sugar cane which has a smaller molecular size which can exfoliate deeper into the skin. We include Salicylic Acid (a BHA) derived from willow trees, that works by dissolving keratin within the pores to helping to minimise congestion and inflammation. This serum creates smooth, luminous skin while also reducing the damaging effects of breakouts and congestion that can increase the signs of aging such as hyperpigmentation and rough skin texture

0.25% Encapsulated Retinol

Our 0.25% Encapsulated Retinol Serum should be incorporated into your evening skin routine a couple of nights a week and then increased in frequency as tolerated. This serum is going to protect existing collagen while promoting further collagen synthesis. As the name suggests, our serum contains 0.25% Encapsulated Retinol. While some other serums boast a higher concentration of Retinol due to the stability created by encapsulating our retinol, this is better absorbed than unencapsulated retinol allowing it to reach deeper layers of the dermis to allow for incredible results all while minimising the risk of irritation. Retinol works by neutralising free radicals that can damage collagen and inhibits UV induction of what’s known as MMP which is a process that causes collagen degradation.

Retinol is also proven to stimulate fibroblasts to synthesise collagen to improve the strength of our skin, while also promoting cellular turnover and the removal of degraded elastin fibres which helps to improve skin elasticity. With 4% Niacinamide (Vitamin B3) which promotes the production of ceramides which creates a stronger skin barrier which shields our skin from cellular damage and moisture loss. 

Formulating with Aloe Vera Extract which is also demonstrated to increase collagen production while also calming, hydrating and soothing the skin, all which help reduce the signs of aging. Along with Ferulic Acid which is a powerful antioxidant that protects the skin against damaging free radicals to combat premature formation of lines and wrinkles.
