Peptides vs retinol — which to choose and can you combine them?

In short

The table is indicative — skin reaction depends on the specific formula, concentration and individual tolerance.

How does retinol work?

Retinol is a form of vitamin A belonging to the retinoid family. In the skin it is gradually converted into retinoic acid — the active form that speeds up epidermal renewal, smooths texture, evens out skin tone and helps reduce blemishes.

The price of this effectiveness is a transition period called retinisation: in the first weeks the skin may be dry, flaky and sting. Retinol also makes the skin more sensitive to UV radiation, so a daily sunscreen is not an extra but a necessity.

How do peptides work?

Peptides are short chains of amino acids that act as signals for skin cells. Depending on the type, they can stimulate fibroblasts to produce collagen (e.g. Matrixyl), relax expression-muscle tension (e.g. Argireline), carry trace elements (copper peptides) or — as with marine peptides — support the regeneration of the skin barrier.

Peptides do not exfoliate the epidermis or make it sensitive to the sun, so they are well tolerated even by sensitive skin. They work more slowly than retinol, though — an ingredient for regular, long-term use rather than a quick effect.

When to choose peptides and when retinol?

How to combine peptides and retinol — 3 schemes

Peptides and retinol are not mutually exclusive — a well-composed routine often uses both. Peptides soothe and support the skin barrier, which helps the skin cope better with retinol. Here are three proven ways to combine them:

1. Peptides in the morning, retinol in the evening — the simplest scheme. In the morning a peptide serum, moisturiser and SPF; in the evening retinol followed by a cream.
2. Alternating — retinol every second (or third) evening, peptides on the other evenings. A good choice to start with and for sensitive skin.
3. One product with both ingredients — formulas combining retinol with peptides are designed so the ingredients work together. Convenient, but it still requires a gradual introduction and SPF.

With high retinol concentrations and simultaneous use of exfoliating acids it is safer to separate applications in time, so as not to overload the skin with too many active ingredients at once.

Sample routine with Larens peptides

If you already use a retinol from another brand, you can weave Larens peptides into your routine using the "peptides in the morning, retinol in the evening" scheme:

• Morning: Biopeptide Serum Spray → Hydro Balance Face Cream → Sunvera SPF50 Face Cream,
• Retinol evening: cleansing → your retinol → moisturiser,
• Retinol-free evening: cleansing → Biopeptide Serum Spray → moisturiser.

Bakuchiol — a compromise for sensitive skin

Bakuchiol is a plant-derived ingredient often called "plant retinol". It supports smoother skin and a more even tone, but unlike classic retinol it does not make the skin sensitive to the sun and is usually better tolerated. You will find bakuchiol combined with peptides in, for example, The One Man Face Cream. Read more about it and other ingredients on the Active ingredients page.

Most common mistakes

• Starting retinol too fast — daily use from day one increases the risk of irritation; it is better to start with 2–3 times a week,
• No SPF — with retinol this is the most common cause of discolouration and irritation,
• Too many actives at once — retinol, acids and vitamin C in one routine easily overload the skin,
• Expecting quick results from peptides — they need systematic use for several weeks or months,
• Introducing several new products at the same time — if the skin reacts, it is hard to tell which one caused it.
