Peels & Exfoliation

What are chemical peels?

A chemical peel is a medical-aesthetic procedure that involves the controlled application of dermal acids to the skin to produce a chemical exfoliation of its superficial or intermediate layers. This process removes damaged, dead cells, stimulates cellular renewal and activates the synthesis of new collagen and elastin.

The result is skin with improved texture, a more even tone, reduced dark spots and greater radiance. The degree of renewal and the intensity of the outcome depend on the concentration and type of acid used, the depth of penetration and the number of layers applied. Dr. Jenny Ortega De La Rosa designs each peel protocol individually, according to the patient's phototype, primary concerns and the time of year.

Pre-treatment preparation required

Before a medium or deep peel it is essential to prepare the skin with retinol and/or depigmenting agents for 2–4 weeks. This preparation improves the uniformity of the result and reduces the risk of post-inflammatory hyperpigmentation, particularly in darker skin types.

How do chemical peels work?

To understand why a peel renews the skin it helps to look at what happens beneath the surface. The applied acid causes a controlled chemical exfoliation: it systematically breaks the bonds between the superficial cells of the epidermis (and even part of the dermis, depending on depth) and promotes their shedding. The skin responds to this stimulus by activating its own repair process.

That process has several complementary effects. First, cellular turnover renewal: by removing the damaged layers, the new cells that replace them migrate in a more organised manner, with better texture and a more even tone. Second, pigment redistribution: the acid helps disperse the melanin accumulations that form dark spots, so tone becomes progressively more uniform over successive sessions. Third, in deeper peels, the stimulus reaches the dermis and activates fibroblasts that produce new collagen and elastin, contributing to improved firmness and softer fine lines.

Depth = result and recovery

The deeper the acid penetrates, the greater the renewal potential — but also the longer the recovery and the more demanding the aftercare. Depth is not chosen for “intensity” alone; it is chosen for the indication: the concern being treated, the phototype and the recovery time each patient can manage. All of this is defined at the consultation.

It is important to understand that the result of a peel is progressive and, for many indications (such as melasma or texture), depends on a multi-session protocol combined with a good home maintenance routine. The skin’s response varies from person to person and is assessed at the consultation.

Mechanism of action by acid type

Different acids achieve exfoliation through distinct mechanisms. Alpha-hydroxy acids (AHAs) such as glycolic and mandelic acid work primarily by dissolving the intercellular cement between epidermal cells. Beta-hydroxy acids (BHAs) such as salicylic acid are lipophilic, allowing them to penetrate sebaceous follicles and act from within the pore. Trichloroacetic acid (TCA) acts by precipitating epidermal proteins, producing a more profound and visible renewal effect. Understanding these differences is what allows a well-trained practitioner to match the acid to the indication.

Types of chemical peels

Peels are classified by depth of action, which determines the type of acid used and the expected recovery time:

🌟
Superficial — AHA / BHA
Glycolic, mandelic, salicylic or lactic acid. For radiance, texture and pores. No visible peeling. No downtime.
🔶
Medium — TCA 20–35%
Trichloroacetic acid. For dark spots, sun damage, irregular texture and fine lines. Skin peeling for 5–7 days.
🔴
Deep — Jessner / TCA 50%
For severe sun damage, deep wrinkles and scars. Greater impact. Recovery 10–14 days.
Vitamin C peel
High-concentration ascorbic acid. Antioxidant, depigmenting and collagen-stimulating effect. Highly luminising.
🌿
Retinol peel
Medical-grade retinol for cellular renewal, texture and fine lines. Mild peeling for 2–4 days.
💎
Mandelic peel
Ideal for sensitive skin and darker phototypes. Gentle, progressive action with lower risk of hyperpigmentation.

Another useful way to understand peels is by the acid used, since each has a distinct profile. The table below summarises the most commonly used acids in orientative terms. This is not a self-prescribing guide: the acid, concentration and number of layers are determined by Dr. Jenny at the consultation, based on your skin.

AcidType / DepthTypical indicationsKey considerations
Glycolic (AHA) Widely usedSuperficialRadiance, texture, pores, dull skinSmall molecule, fast penetration; neutralised by time
Mandelic (AHA)SuperficialSensitive skin, darker phototypes, dark spots, acneGentler, more progressive action; lower irritation risk
Salicylic (BHA)SuperficialOily skin, acne, enlarged pores, blackheadsLipophilic: acts inside the pore; sebum-regulating effect
Lactic (AHA)SuperficialHydration, radiance, dry or sensitive skinAmong the gentlest; good tolerability
TCA (trichloroacetic)Medium (varies with %)Sun spots, irregular texture, fine lines, scarsPre-treatment preparation required; visible peeling for several days
Jessner solutionMediumSun damage, hyperpigmentation, acne; often combined with TCABlend of several acids; applied in controlled layers

Benefits of chemical peels

Chemical peels offer a broad range of skin benefits when correctly indicated and performed by a trained medical professional. The most consistent outcomes include:

Who is a candidate? (and when NOT)

A chemical peel is not a one-size-fits-all treatment: what makes it safe and effective is proper patient selection. As a general guide, you are a good candidate if you identify with any of the following profiles:

When a peel is not the best option. A chemical peel is postponed or ruled out — and an alternative is sought — in several situations: during pregnancy and breastfeeding; if you have taken isotretinoin in the past several months; in the presence of active herpes or active skin infections in the treatment area; if you have open wounds, dermatitis or eczema on the face; or if you will not be able to avoid sun exposure during the recovery period. For darker phototypes (IV–VI) deeper peels are indicated with caution and pre-treatment preparation given the risk of hyperpigmentation. And when the concern is a marked wrinkle or significant laxity, a peel alone will not resolve it — in those cases other options should be evaluated. The evaluation consultation exists precisely to distinguish these scenarios and avoid recommending a peel when it is not appropriate.

The procedure, step by step

A chemical peel session lasts between 30 and 45 minutes. The procedure varies according to the depth of the prescribed peel:

  1. 1
    Assessment and pre-treatment preparation Skin type, phototype and goals are evaluated. For medium or deep peels, a 2–4 week preparation protocol with retinol and/or depigmenting agents is prescribed to homogenise the skin's response.
  2. 2
    Cleansing and degreasing The face is thoroughly cleansed with a specific solution to remove all traces of oil or cosmetics that could interfere with the uniform penetration of the acid.
  3. 3
    Acid application The acid is applied evenly with a brush or gauze, layer by layer, while monitoring contact time and the skin's response (erythema, frosting). It is neutralised at the appropriate moment according to the acid type.
  4. 4
    Immediate aftercare A moisturiser and sunscreen are applied at the end of the session. A post-peel aftercare protocol is provided: intensive hydration, strict sun protection and avoidance of direct sun exposure during the peeling phase.
Sunscreen is non-negotiable

After any chemical peel, SPF 50+ sunscreen every day without exception is mandatory. Post-peel skin is more vulnerable to UV radiation and may develop hyperpigmentation if not adequately protected.

Aftercare and recovery

A significant part of the peel result depends on what happens after the session. Recovery varies considerably by depth: a superficial peel usually allows a return to normal routine the same day, while a medium or deep peel involves several days of peeling and more specific care. What to expect at each level is explained at the consultation before you begin.

Recovery recommendations

Warning signs — always contact the clinic

Complications are uncommon when a peel is correctly indicated and properly cared for. Even so, if you experience intense or persistent burning, blistering, signs of infection (growing redness, warmth, discharge or pus), or the appearance of new dark patches, contact the clinic. Recovery monitoring is included in the treatment and allows any concerns to be addressed promptly.

Chemical peels vs. other options

Chemical peels do not compete with other skin treatments — they often complement them within the same plan. Understanding what each technique does best helps set realistic expectations and make informed decisions. The following is an honest, orientative comparison:

OptionBest suited forRecovery
Chemical peelDark spots, uneven tone, texture, pores, radiance and fine linesNone to several days depending on depth
MicroneedlingTexture, acne scars and firmness through mechanical collagen stimulationBrief redness, 1–3 days
Botulinum ToxinDynamic expression lines (frown, forehead, crow’s feet)Virtually none
Hyaluronic acidVolume loss and deep creases; does not act on spots or textureMinimal
Facial cleansingDeep hygiene and comedone extraction; does not renew or depigmentNone

In practice, a comprehensive skin plan may combine a peel for tone and texture with other treatments for volume or expression lines. What is appropriate for your case — and in what sequence — is defined at the evaluation consultation.

Frequently asked questions about chemical peels

After a superficial peel you can apply makeup the following day. After a medium peel you need to wait 5–7 days until peeling is complete and the new skin has consolidated. After a deep peel, recovery without makeup is 10–14 days. SPF 50+ sunscreen is essential from the very first day after any peel.
Superficial peels produce a mild tingling or burning sensation that lasts a few minutes and subsides once the acid is neutralised. Medium peels may cause a more intense burning sensation that is relieved with fanning during application. Deep peels require local anaesthesia or sedation to ensure patient comfort.
Superficial peels can be performed at any time of year as long as adequate sunscreen is used consistently. Medium and deep peels are preferably recommended in autumn and winter, when sun exposure is lower and the risk of post-inflammatory hyperpigmentation is reduced. In summer, superficial maintenance peels are a suitable option.
It depends on the type and depth of the spots. For superficial sun-related spots, a medium peel can show progressive improvement, assessed at follow-up. For melasma, a protocol of several superficial peel sessions with continuous maintenance is usually required, as melasma tends to recur with sun exposure. The individual response varies from patient to patient and is evaluated at the consultation.
The difference lies in how deep the acid penetrates. A superficial peel works on the epidermis (radiance, texture, pores) and involves virtually no downtime. A medium peel reaches deeper and is used for dark spots, sun damage and fine lines, with several days of peeling. A deep peel targets inner skin layers for severe sun damage or scars, with longer recovery and specific aftercare. Depth is chosen based on the indication, skin phototype and each patient’s available recovery time.
The duration of results varies depending on the patient, the type of peel, the concern being treated and, above all, aftercare. Skin continues to age naturally, and for conditions such as melasma sun exposure promotes recurrence, which is why maintenance protocols are usually planned. Daily sun protection and a good home routine help sustain results. The specifics for your individual case are defined at the consultation.
Yes. With medium and deep peels, skin peeling is an expected part of the renewal process; with superficial peels there may be no visible flaking at all. The key is not to pick or rub the peeling skin — let it fall off on its own to minimise the risk of marks or post-inflammatory pigmentation. Intensive moisturising and sun protection support this stage.
Yes, but with careful selection. For darker phototypes (IV–VI), well-indicated superficial peels such as mandelic acid are preferred, and pre-treatment with depigmenting agents is recommended to reduce the risk of post-inflammatory hyperpigmentation. Deeper peels are used with caution in these skin types. A prior phototype assessment determines which protocol is safe in each case.
Yes. Peels address tone, dark spots and texture, and can be combined within a treatment plan alongside other modalities that target different concerns — such as botulinum toxin for expression lines or hyaluronic acid for volume. What to combine, in which order and at what intervals is defined at the consultation so that each technique contributes without overloading the skin.
Superficial peels generally require no special preparation. For medium and deep peels, however, it is recommended to prepare the skin for 2–4 weeks with retinol and/or depigmenting agents: this homogenises the skin’s response, improves uniformity of the result and reduces the risk of post-inflammatory pigmentation, especially in darker skin types. Preparation is prescribed at the consultation.
