This BB cream is a combination of moisturiser, SPF and cover-up and will reduce redness, the appearance of spots and brighten the appearance of the skin.

Soothe redness and inflammation

Leave a flawless, natural-looking glow
Suitable for all skin types.

Non- comedogenic, lightweight, and breathable.
Directions:
Apply sparingly every morning. But make sure to spread it evenly across your face, like you would a moisturiser.
As we age our collagen production reduces, this can make our skin look dull, tired and wrinkles can start to form. It’s collagen that gives our skin a firm and youthful look. This collagen mask is infused with hydrolyzed collagen as well as various other anti-ageing ingredients (listed below). Using this mask will promote plump, firm and elastic skin.
WHAT IS COLLAGEN?
Collagen is the most abundant protein in the body making up to 25-35% of the whole bodies protein content. It is the fundamental component of connective tissues such as tendons, ligaments, skin and muscles. Collagen helps to give the skin structure as well as enabling skin cells to repair faster and regenerate.
BENEFITS OF COLLAGEN
Added hydrationIf you struggle with dry skin collagen, through using a collagen mask, can help add moisture. Even if you have a regular skin type, added hydration can be of benefit to keep your skin moisturised especially if you have had exposure to the sun or a lack of sleep.Skin rejuvenationA collagen mask is an excellent addition to a weekly skin regime to help keep your skin looking fresh and young. Collagen will help reduce fine lines, wrinkles and in some cases age spots.Reduction of natural collagen production with ageBy the time you reach 30, your skin will not produce collagen at the same rate as it did when you were younger. As you get older, this natural collagen production continues to decrease, so by using collagen-boosting products you keep your skin naturally looking younger.
HOME USE
When using this product at home, we always advise washing your face, preferably with a cleanser first, we recommend the Genosys Snow Cleanser which works excellently with this collagen mask. Following using the Snow Cleanser we recommend using a light exfoliator to remove any other dirt from the surface of the skin. This mask will also work well if you use a shorter needled dermaroller at home.

Its nice to meet you…
Hi, I’m Catherine — skin coach, facialist and founder of Catherine Costas Beauty.
With over 10 years’ experience in advanced skin treatments, I specialise in supporting women through hormonal breakouts, sensitivity, rosacea, dullness and skin barrier concerns — especially during perimenopause, menopause and stressful life seasons.
My approach is different because I don’t believe in quick fixes. I focus on skin barrier repair, long-term skin health, and the deeper internal triggers that can show up on the skin. I work with organic, non-toxic, hormone-conscious skincare designed to strengthen the skin — not strip it.
I’m also currently completing a Diploma in Health + Wellness Coaching, allowing me to support clients with the lifestyle factors that influence skin health too — including gut health, inflammation, stress and daily habits.
Whether you visit me in clinic or choose online coaching, you’ll receive a calm, supportive experience and a personalised plan to help your skin feel clear, strong and glowing again.
Based in St Albans, Hertfordshire, my private skin clinic offers a calm and personalised experience focused on skin health, confidence and long-term results.
