If you’ve been part of the esmi family for a while, you’ll know our devotion to Retinol and Vitamin C runs deep. These two heavy-hitters anchor many of our routines for good reason. The results can be transformative – think: luminous, smoother, firmer-looking skin - provided you use them correctly.

Vitamin C: Your morning glow-getter

Products: 

• Brightening 15% Vitamin C Serum

Vitamin C is the ultimate multi-tasker. As a potent antioxidant, it helps neutralise free radicals caused by pollution and UV exposure – both known to accelerate the visible signs of ageing. It also plays a vital role in collagen synthesis and helps inhibit excess melanin production, meaning dark spots appear less pronounced over time.

And while Vitamin C supports your skin against UV damage, it is not a substitute for sunscreen. Think of it as your SPF’s stylish best friend – strong alone, unstoppable together. The result? Skin that looks brighter, clearer and more luminous.

Retinol: The hero of your PM routine

Products: 

• Encapsulated Retinol 0.25% Level 1

• Encapsulated Retinol 0.50% Level 2

• Encapsulated Retinol 0.75% Level 3

• Encapsulated Retinol 1.0% Level 4

Derived from vitamin A, Retinol is renowned for accelerating cell turnover and stimulating collagen production. Translation: brighter-looking skin, softened fine lines and a fresher, more refined complexion.

It’s also a quiet achiever for breakout-prone skin, helping to decongest pores and lightly exfoliate. When it comes to premature ageing, Retinol is less trend and more gold standard.

If you’re new to Retinol, start low and slow. A peal sized amount every second night is plenty. Some mild adjustment (think slight dryness or flaking) can happen at first, but consistency – and patience – pays off.

Can you use Retinol and Vitamin C together?

Short answer: yes. Long answer: not at the same time.

Both ingredients are highly active, and layering them can overstimulate the skin, leading to irritation and a compromised barrier – which, ironically, makes skin more vulnerable to environmental stressors.

There’s also the science. Retinol and Vitamin C perform best at different pH levels. Apply them together and you risk destabilising both, reducing their potency and limiting results.

The smarter approach? Separate them by time of day.

How to make them work

Use Vitamin C in the morning to amplify brightness and antioxidant protection. Brightening 15% Vitamin C Serum delivers a potent concentration designed to visibly improve pigmentation, boost radiance and support collagen production – ideal for skin showing signs of dullness, sun damage or uneven tone.

Retinol belongs in your evening routine. Because it increases photosensitivity, it’s strictly an after-dark treatment. The Encapsulated Retinol range is formulated to deliver actives deeper into the skin with reduced irritation. Begin with Level 1 and only increase once your skin has comfortably adjusted.

And every single morning? Wear sunscreen – and make sure it’s SPF50+. It's non-negotiable, especially when using actives.

Retinol and Vitamin C may not share the same step, but when used strategically, they form one of skincare’s most powerful alliances. Glow by day, renew by night – and let consistency do the rest.
