Environ Youth EssentiA Intensive Serum 4 Plus is the final, highest level in Environ's premium Vitamin A Step-Up System — the level you maintain once your skin is fully acclimatised. It combines a very high concentration of Vitamins A, C and E with antioxidants and peptides to repair, protect and normalise the skin.
Together, these actives help combat the visible signs of ageing: softening the appearance of lines and wrinkles, improving loss of tone and firmness, and refining uneven skin tone for a smoother, more radiant, healthier-looking complexion.
Suitable for all skin types, and especially valuable for mature and photo-damaged skin ready for the highest level of active care.

Frequently Asked Questions
Frequently Asked Questions
Q. Should I use Serum 4 Plus if I'm new to Environ?
A. No — it's the highest level of the Youth EssentiA system. Start lower and step up so your skin builds tolerance to Vitamin A. Book a consultation to confirm your starting point.
Q. What moisturiser goes with Intensive Serum 4 Plus?
A. It's designed to be layered under Youth EssentiA Antioxidant Defence Crème Plus, which together form the complete high-strength routine.
Q. Does this serum contain sunscreen?
A. It contains a sunscreen to protect the active ingredients, but you should still apply a dedicated broad-spectrum SPF every morning.
Q. Why is it more expensive than other serums?
A. It carries the highest concentration of Vitamins A, C, E and peptides in the Youth EssentiA range, and a little is used at each application, so a 35ml bottle can last a couple of months.

Breakouts and fine lines at the same time?! The wonderful world of perimenopause.
The search for the perfect moisturiser can seem never ending amidst the overwhelming sea of beauty products. However, I can vouch for the quality and effectiveness of the Youth EssentiA range - my skin has found a lasting radiance and firmness. Devoted use (now Serum 4 plus) has lead to a reduction in fine lines and improved skin texture. Yes, the price tag is significant but for this 67 year old the Environ range is worth every penny!
I have used Youth EssentiA Intensive serums working up from 1 & now at 4plus for many many years and for the last couple of years combined this with defence creme plus. I am 61 years old and get amazing comments about my skin. Expensive but highly recommended. I also use the peptide eye gel.
At 56 years old, people say to me my skin looks good - I have been using Environ for the last 12 years or so, proof that this product works!
Been usingvthis for years with great results
Been using Environ for almost 20 years and at 60 my skin is better than ever. I would never use anything else.
