Retinol

Vitamin A is the most studied anti-ageing active there is. It speeds cell turnover and stimulates collagen, which is why it works on established lines, rough texture and pigmentation — and why it belongs at night, introduced slowly.

Two or three nights a week, on dry skin, with a moisturiser after. Build up as your skin tolerates it. If you flake or sting, drop back and rebuild with ceramides. Gentler peptide formulas like Firming Elasticity Repair reach a similar goal with less irritation.

The Retinol Serum — fast-absorbing, for deep lines, texture, pores and age spots. It also comes in the Serum Bundle with vitamin C and hyaluronic acid.

Fine lines and wrinkles, rough texture, enlarged-looking pores and dark spots — it is the most versatile single anti-ageing active, used at night.

Yes — the simplest split is vitamin C in the morning and retinol at night, with gentle peptides useable either time. Introduce one active at a time.

Start at two or three nights a week and build towards nightly as tolerated. More frequent is not better if it leaves skin raw.

It can at first — some flaking or breakouts as turnover speeds up. Ease in slowly, buffer with a moisturiser, and it usually settles within a few weeks.

Used carefully, yes — low frequency, buffered with moisturiser, and paired with ceramides. If it is too much, gentle peptides are a lower-irritation route to firmer, smoother skin.

The eye area is delicate — keep a dedicated eye treatment such as PRIME Eye for there, and keep strong retinol off the lid.

Yes, without exception. Retinol increases sun sensitivity, and using it without daily SPF undoes the work.
