Discover Environ Youth EssentiA sets, C-Quence serum twin sets and skincare trios to support your daily routine. Combining vitamins, antioxidants and peptides, the Youth EssentiA range helps improve the appearance of skin texture, firmness and radiance. Replenish your current favourites or explore a complementary combination, choosing the vitamin A level your skin is comfortable with. Unsure where to start?

Choose an Environ Youth EssentiA set for your routine

Environ Youth EssentiA is a vitamin A skincare range built around the Vitamin STEP-UP SYSTEM. Its C-Quence serums combine vitamins A, C and E with antioxidants and peptides to help skin look smoother, more even and firmer.

This collection brings together replenishment twin sets and skincare trios. Whether you already use C-Quence or are considering the range for the first time, start by identifying the products and serum levels that suit your existing routine.

Twin sets or skincare trios: which should you choose?

Twin sets are a practical choice when you already know a product suits your skin. Explore C-Quence serum twin sets alongside Youth EssentiA cleansing lotion, toner, eye gel and Defence Crème options. Check the individual product page for exact contents and sizes.

Skincare trios pair a selected C-Quence serum and Defence Crème option with an additional product. Choose from combinations featuring Avance Elixir, Intense C-Boost Mela-Even Cream, 3D Filler Crème or Retinol Serum. Read each set’s product guidance before adding a new active ingredient to your routine.

Choose your C-Quence level with confidence

C-Quence Serum 1 is the first step in the Youth EssentiA Vitamin STEP-UP SYSTEM. The sequence continues through Serums 2, 3 and 4 to the advanced Serum 4 Plus stage. Progress gradually, guided by your skin’s comfort and professional advice.

Defence Crème Plus is also an advanced step, so check its suitability before selecting it for a set.

For individual products, explore the complete Environ Youth EssentiA range. For help choosing a set or moving between levels, book a skincare consultation.

Frequently Asked Questions

Is Environ C-Quence the same as Youth EssentiA?

C-Quence is the serum in Environ’s Youth EssentiA range. Youth EssentiA also includes cleansing lotion, toner, eye gel and Defence Crème. A C-Quence serum twin set replenishes your serum, while a skincare trio combines products for different roles in your routine.

Which C-Quence serum level should I choose?

Choose according to your current vitamin A routine and your skin’s tolerance. C-Quence Serum 1 is the first level in the Youth EssentiA system; you can add higher levels progressively. If you are new to Environ, or returning after a break, ask Chelleon for advice before choosing your level.

When should I move up from C-Quence Serum 1?

Environ recommends using at least two bottles of C-Quence Serum 1 before progressing to Serum 2. Your skin should also be comfortable at the current level. Finishing two bottles doesn't mean you must move up immediately; seek advice if you are experiencing irritation or aren't sure whether to progress.

What is the difference between Defence Crème and Defence Crème Plus?

Antioxidant Defence Crème is the moisturising partner for C-Quence Serums 1–4. Defence Crème Plus contains vitamin A and represents the advanced stage of the Youth EssentiA system.

How do I apply C-Quence serum and Defence Crème?

After pre-cleansing, cleansing and toning, apply your recommended C-Quence serum, then Antioxidant Defence Crème. For C-Quence Serum 1, you can also mix the serum and crème in your palm before application. Use this routine morning and evening; follow your individual product instructions and any personalised advice. Use a separate broad-spectrum sunscreen during the day.

What is the difference between C-Quence and AVST?

C-Quence is part of the Environ Youth EssentiA range and uses a serum paired with a separate Defence Crème. AVST is part of the Skin EssentiA range and delivers its vitamin A step-up routine through moisturisers. Both ranges use progressive vitamin A levels, but the numbers don't map directly. Seek advice before switching ranges.

Can I use an additional retinol serum with C-Quence?

Environ positions its Focus Care Youth+ Retinol Serums as an additional step for skin already accustomed to higher vitamin A levels. A trio containing Retinol Serum should match your experience and tolerance. Ask Chelleon to confirm suitability and advise on how to introduce it before adding it to your C-Quence routine.

Talking Colostrum C

I have been taking Colostrum-C for a quite a few years now. Like with most supplements, one will never know what would have happened without it but for me, it has done what it says on the tin and lived up to my expectations.

Stepping Up!

Have worked up to this over the years and now cocktail it with AVST5. Skin looking youthful, even if I do say so myself! To be fair, others frequently comment as well.

I have found that the concealer is very easy to apply and is not sticky and thick to apply and gives a nice even finish
