Skincare trends change quickly, but choosing an effective routine still starts with the same questions: what concern are you addressing, what evidence supports the ingredients, and can your skin tolerate consistent use? This guide explores seven relevant areas of skincare in 2026, from established retinoids and sun protection to newer approaches involving peptides, exosomes and skin changes after weight loss.

The categories below serve different purposes. Some are cosmetic skincare options; others involve prescription treatments requiring individual assessment. They are not seven steps that everyone needs to add to a routine.

1. GLP-1–related facial skin changes

Substantial weight loss can change facial contours and make skin laxity, dryness and fine lines more noticeable. These changes are often described as “Ozempic face” when they occur during treatment with weight-management medicines, but similar changes can accompany weight loss through other methods.

It is useful to distinguish changes in facial volume from changes in skin quality. A moisturising or firming skincare product may improve the appearance of dehydration, surface texture and fine lines without replacing lost facial fat. Understanding that distinction helps set realistic expectations and identify whether the main concern is skin dryness, visible laxity, reduced volume or a combination.

A supportive routine can focus on gentle cleansing, comfortable moisturisation, sun protection and carefully selected treatment products. If skin becomes more sensitive, adding several strong actives at once can make the routine harder to tolerate.

See our articles on GLP-1 facial volume loss and VOL.U.LIFT and skin changes after weight loss for more detail.

2. Advanced peptides

Peptides are short chains of amino acids used in skincare formulations targeting concerns such as the appearance of fine lines, firmness and skin texture. Different peptides have different properties, so “peptide serum” describes a broad category rather than one standard treatment.

When assessing a peptide product, the finished formulation matters. Evidence for an individual ingredient does not automatically establish the results of every product containing it. Concentration, stability, delivery and the other ingredients in the formula all influence how a product performs.

Peptide products can have a useful place in routines focused on visible skin quality, particularly when their moisturising texture makes them comfortable to use consistently. They should be selected for a specific role rather than added simply to increase the number of active ingredients in a routine.

See our complete guide to peptides in skincare for an explanation of the main categories and how to assess them.

3. Exosomes and related skincare technologies

Exosomes and related cell-signalling technologies are an emerging area of skincare research. Products marketed within this category can differ substantially in their source material, composition, manufacturing and supporting evidence.

The term “exosome” alone does not tell you whether a finished product has been clinically evaluated or whether findings from another formulation apply to it. Laboratory research, small clinical studies and evidence for a specific commercial product should be considered separately.

For anyone considering these products after a procedure, the treating clinician should advise on suitability and timing. A cosmetic product intended for intact skin should not be assumed suitable for use on broken skin, after microneedling or by injection.

See our science guide to exosomes for further background on this developing category.

4. Tretinoin

Tretinoin is a prescription topical retinoid used in clinical dermatology. It has an established research history in acne and photoageing, but suitability depends on the individual, the formulation and the reason for treatment.

Its role in a routine is a prescribing decision. Dryness, redness and irritation can affect tolerability, and using more frequently or choosing a higher strength does not automatically produce a better outcome. A clinician may adjust application frequency, supporting skincare and follow-up according to the response.

Tretinoin should not be treated as an automatic progression from cosmetic retinol. Some people can address their concerns with non-prescription skincare, while others need assessment for a skin condition or a different treatment approach. Topical retinoids should not be used during pregnancy or when planning pregnancy.

For educational information, see our beginner’s guide to starting tretinoin and our UK consultation and prescribing guide.

5. Retinol and retinal

Retinol and retinal, also called retinaldehyde, are cosmetic retinoids used for the appearance of fine lines, uneven tone and texture. Retinol is converted to retinal and then retinoic acid in the skin; retinal is one conversion step away from retinoic acid.

That biochemical difference does not make percentages directly interchangeable between products. The formulation, stability, frequency of application and individual tolerance all matter. A well-tolerated product used consistently may be more useful than a stronger product that repeatedly causes irritation.

Introduce a retinoid gradually, follow the product’s instructions and support the routine with moisturiser and daytime sun protection. Avoid combining several retinoid products unless specifically advised to do so.

Changes to EU rules for certain vitamin A ingredients have also prompted questions about product strengths and reformulation. These are restrictions on specified cosmetic ingredients, not a blanket ban on every retinoid. Their implications depend on the ingredient and the market in which the product is supplied.

See our guide to retinol and our article on EU retinol regulation for more detail.

6. Hyperpigmentation treatments and hydroquinone

Uneven pigmentation can have different causes, including melasma, sun exposure and inflammation following acne or irritation. Identifying the cause matters because a treatment appropriate for one presentation may not be appropriate for another.

Hydroquinone is used under medical supervision for selected pigmentation concerns, including melasma. Treatment choice, duration and monitoring require individual assessment. It should not be presented as the default option for everyone with dark marks or uneven skin tone.

Other ingredients used in pigmentation routines include azelaic acid, niacinamide, tranexamic acid and arbutin. Their roles differ, and suitability depends on the formulation, the type of pigmentation and skin tolerance. Non-prescription options may be appropriate in their own right, rather than merely as a substitute for prescription treatment.

Sun protection and avoiding unnecessary irritation remain important parts of pigmentation care. A changing, unusual or undiagnosed pigmented lesion should be assessed rather than treated as a routine cosmetic dark spot.

See our guide to skincare routines for hyperpigmentation and our guide to hydroquinone alternatives for further information.

7. Broad-spectrum sun protection

Sun protection is a foundation of skincare for visible ageing and uneven pigmentation. Choose a broad-spectrum sunscreen with SPF 30 or higher. SPF 50 is an option for those seeking a higher level of UVB protection, but SPF 30 is not automatically inadequate simply because someone uses an active skincare ingredient.

Apply sunscreen generously to exposed skin and reapply approximately every two hours when outdoors, and after swimming, sweating or towelling, following the product’s instructions. Shade, clothing and a hat provide additional protection.

The most useful sunscreen is one with appropriate protection that you will apply adequately and consistently. Texture, comfort and compatibility with the rest of the routine can therefore matter as much as choosing between high SPF numbers.

How to put these categories into a practical routine

Start with cleansing, moisturising and sun protection. Then identify the main concern you want to address and choose a targeted product or seek assessment where necessary. Introduce changes gradually so that you can recognise what helps and what causes irritation.

There is no requirement to combine peptides, exosomes, retinoids and pigmentation treatments. A focused routine with a clear purpose is easier to assess and maintain than one containing overlapping products.

Prescription treatment requires an individual medical assessment. A consultation may result in a different treatment recommendation or no prescription.

Frequently asked questions

What is the most important starting point for an anti-ageing skincare routine?

Consistent sun protection is a useful starting point, alongside a moisturiser suited to your skin. Targeted products can then be selected according to the concern, such as fine lines, uneven tone or dryness.

Does everyone need tretinoin?

No. Tretinoin is a prescription medicine whose suitability depends on clinical assessment. Cosmetic skincare may be sufficient for some concerns, while others require a different treatment or diagnosis.

What is Ozempic face, and can skincare help?

The term describes facial changes that may become noticeable after substantial weight loss, including reduced fullness and more visible laxity or lines. Skincare can address aspects of hydration and surface appearance, but it does not replace lost facial fat. See our article on GLP-1 facial volume loss.

Are exosome products essential?

No. They are an emerging category, and products vary considerably. Assess the evidence and directions for the specific formulation rather than assuming all products marketed as exosomes have equivalent effects. Our exosome science guide explores the category further.

Is retinal always better than retinol?

No single ingredient is the best choice for every person. Retinal and retinol differ in their conversion pathway, but the finished formulation and your ability to tolerate regular use are important. Percentages cannot be compared as though the two ingredients were identical.

Is there a blanket EU ban on retinol?

No. EU rules restrict specified vitamin A ingredients in cosmetics; they do not prohibit every retinoid. See our explanation of EU retinol regulation for the distinction.

Do prescription skincare users always need SPF 50?

Broad-spectrum SPF 30 or higher is the general recommendation. SPF 50 can provide additional UVB protection. Follow any specific advice from your clinician, apply enough product and use other sun-protection measures.

Should I add all seven categories to my routine?

No. These categories address different needs and include both cosmetic products and prescription treatments. Select products for a defined purpose, introduce them gradually and seek professional assessment for persistent or uncertain skin concerns.
